Page 55: Sflow
The PowerConnect 8024 and 8024F switches support sFlow version 5. For information about configuring managing sFlow settings, see "Monitoring Switch Traffic"...
Page 56: Stacking Features
"Managing a Switch Stack" on page 125. High Port Count You can stack PowerConnect 8024/8024F switches up to six switches high, supporting up to 132 front-panel ports when two ports on each unit are configured as stacking ports. The stack can contain any combination of Power Connect 8024 and PowerConnect 8024F switches as long as all switches are running the same firmware version.
Page 57: Master Failover With Transparent Transition
Master Failover with Transparent Transition Standby The stacking feature supports a or backup unit that assumes the Master unit role if the Master unit in the stack fails. As soon as a Master failure is detected in the stack, the Standby unit initializes the control plane and enables all other stack units with the current configuration.
Page 58: Password-Protected Management Access
Password-Protected Management Access Access to the Web, CLI, and SNMP management interfaces is password protected, and there are no default users on the system. For information about configuring local user accounts, see "Controlling Management Access" on page 159. Strong Password Enforcement The Strong Password feature enforces a baseline password strength for all locally administered users.
Page 59: Ssh/Ssl
SSH/SSL The switch supports Secure Shell (SSH) for secure, remote connections to the CLI and Secure Sockets Layer (SSL) to increase security when accessing the Web-based management interface. For information about configuring SSH and SSL settings, see "Controlling Management Access" on page 159. Inbound Telnet Control You can configure the switch to prevent new Telnet sessions from being established with the switch.
Page 60: Dot1X Authentication (Ieee 802.1X)
Dot1x Authentication (IEEE 802.1X) Dot1x authentication enables the authentication of system users through a local internal server or an external server. Only authenticated and approved system users can transmit and receive data. Supplicants are authenticated using the Extensible Authentication Protocol (EAP). Also supported are PEAP , EAP-TTL, EAP-TTLS, and EAP-TLS.
Page 61: Access Control Lists (Acl)
Access Control Lists (ACL) Access Control Lists (ACLs) ensure that only authorized users have access to specific resources while blocking off any unwarranted attempts to reach network resources. ACLs are used to provide traffic flow control, restrict contents of routing updates, decide which types of traffic are forwarded or blocked, and above all provide security for the network.
Page 62: Dhcp Snooping
DHCP Snooping DHCP Snooping is a security feature that monitors DHCP messages between a DHCP client and DHCP server. It filters harmful DHCP messages and builds a bindings database of (MAC address, IP address, VLAN ID, port) tuples that are specified as authorized. DHCP snooping can be enabled globally and on specific VLANs.
Page 63: Switching Features
For information about how to configure the AFS CLI Reference Guide feature, see the available at support.dell.com/manuals. Jumbo Frames Support Jumbo frames enable transporting data in fewer frames to ensure less overhead, lower processing time, and fewer interrupts.
Page 64: Vlan-Aware Mac-Based Switching
PAUSE frame indicating that the transmitter should cease transmission of frames for a specified period. When flow control is enabled, the PowerConnect 8024 and 8024F switches will observe received PAUSE frames or jamming signals, and will issue them when congested.
Page 65: Port Mirroring
Port Mirroring Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from up to four source ports to a monitoring port. The switch also supports flow-based mirroring, which allows you to copy certain types of traffic to a single destination port. This provides flexibility— instead of mirroring all ingress or egress traffic on a port the switch can mirror a subset of that traffic.
Page 66: Priority-Based Flow Control (Pfc)
Priority-based Flow Control (PFC) The Priority-based Flow Control feature allows the user to pause or inhibit transmission of individual priorities within a single physical link. By configuring PFC to pause a congested priority (priorities) independently, protocols that are highly loss sensitive can share the same link with traffic that has different loss tolerances.
Page 67: Cisco Protocol Filtering
VLAN tag or a combination of the ingress port and packet contents. Packets sharing common attributes can be groups in the same VLAN. The PowerConnect 8024 and 8024F switches are in full compliance with IEEE 802.1Q VLAN tagging. Port-Based VLANs Port-based VLANs classify incoming packets to VLANs based on their ingress port.
Page 68: Ip Subnet-Based Vlan
IP Subnet-based VLAN This feature allows incoming untagged packets to be assigned to a VLAN and traffic class based on the source IP address of the packet. MAC-based VLAN This feature allows incoming untagged packets to be assigned to a VLAN and traffic class based on the source MAC address of the packet.
Page 69: Guest Vlan
Guest VLAN The Guest VLAN feature allows a switch to provide a distinguished service to unauthenticated users. This feature provides a mechanism to allow visitors and contractors to have network access to reach external network with no ability to browse information on the internal LAN. For information about configuring the Guest VLAN see "Configuring 802.1X and Port-Based Security"...
Page 70: Spanning Tree Protocol Features
Spanning Tree Protocol Features For information about configuring Spanning Tree Protocol features, see "Configuring the Spanning Tree Protocol" on page 615. Spanning Tree Protocol (STP) Spanning Tree Protocol (IEEE 802.1D) is a standard requirement of Layer 2 switches that allows bridges to automatically prevent and resolve L2 forwarding loops.
Page 71: Bridge Protocol Data Unit (Bpdu) Guard
Bridge Protocol Data Unit (BPDU) Guard Spanning Tree BPDU Guard is used to disable the port in case a new device tries to enter the already existing topology of STP. Thus devices, which were originally not a part of STP, are not allowed to influence the STP topology. BPDU Filtering When spanning tree is disabled on a port, the BPDU Filtering feature allows BPDU packets received on that port to be dropped.
Page 72: Routing Features
For information about managing the ARP table, see "Configuring IP Routing" on page 875. VLAN Routing PowerConnect 8024 and 8024F switches support VLAN routing. You can also configure the software to allow traffic on a VLAN to be treated as if the VLAN were a router port.
Page 73: Bootp/Dhcp Relay Agent
BOOTP/DHCP Relay Agent The switch BootP/DHCP Relay Agent feature relays BootP and DHCP messages between DHCP clients and DHCP servers that are located in different IP subnets. For information about configuring the BootP/DHCP Relay agent, see "Configuring L2 and L3 Relay Features" on page 899. IP Helper and UDP Relay The IP Helper and UDP Relay features provide the ability to relay various protocols to servers on a different subnet.
Page 74: Virtual Router Redundancy Protocol (Vrrp)
For information about configuring VRRP settings, see "Configuring VRRP" on page 1011. Tunnel and Loopback Interfaces PowerConnect 8024 and 8024F switches support the creation, deletion, and management of tunnel and loopback interfaces. Tunnel interfaces facilitate the transition of IPv4 networks to IPv6 networks. A loopback interface is always expected to be up, so you can configure a stable IP address that other network devices use to contact or identify the switch.
Page 75: Ipv6 Routes
IPv6 Routes Because IPv4 and IPv6 can coexist on a network, the router on such a network needs to forward both traffic types. Given this coexistence, each switch maintains a separate routing table for IPv6 routes. The switch can forward IPv4 and IPv6 traffic over the same set of interfaces.
Page 76: Quality Of Service (Qos) Features
The QoS Differentiated Services (DiffServ) feature allows traffic to be classified into streams and given certain QoS treatment in accordance with defined per-hop behaviors. PowerConnect 8024 and 8024F switches support both IPv4 and IPv6 packet classification. For information about configuring DiffServ, see "Configuring Differentiated Services"...
Page 77: Internet Small Computer System Interface (Iscsi) Optimization
Internet Small Computer System Interface (iSCSI) Optimization The iSCSI Optimization feature helps network administrators track iSCSI traffic between iSCSI initiator and target systems. This is accomplished by monitoring, or snooping traffic to detect packets used by iSCSI stations in establishing iSCSI sessions and connections. Data from these exchanges may optionally be used to create classification rules to assign the traffic between the stations to a configured traffic class.
Page 78: Igmp Snooping Querier
IGMP Snooping Querier When Protocol Independent Multicast (PIM) and IGMP are enabled in a network with IP multicast routing, the IP multicast router acts as the IGMP querier. However, if it is desirable to keep the multicast network Layer 2 switched only, the IGMP Snooping Querier can perform the query functions of a Layer 3 multicast router.
Page 79: Layer 3 Multicast Features
The Internet Group Management Protocol (IGMP) is used by IPv4 systems (hosts and routers) to report their IP multicast group memberships to any neighboring multicast routers. PowerConnect 8024 and 8024F switches perform the “multicast router part” of the IGMP protocol, which means it collects the membership information needed by the active multicast router.
Page 80: Protocol Independent Multicast-Sparse Mode
Protocol Independent Multicast—Sparse Mode Protocol Independent Multicast-Sparse Mode (PIM-SM) is used to efficiently route multicast traffic to multicast groups that may span wide area networks, and where bandwidth is a constraint. PIM-SM uses shared trees by default and implements source-based trees for efficiency. This data threshold rate is used to toggle between trees.

Table 7-1. Basic Network Information...
Page 106: Why Is Basic Network Information Needed
Why Is Basic Network Information Needed? PowerConnect 8024 and 8024F switches are layer 2/3 managed switches. To manage the switch remotely by using a Web browser or Telnet client, the switch must have an IP address, subnet mask, and default gateway. You must also configure a username and password to be able to log into the switch from a remote host.
Page 107: How Is Basic Network Information Configured
You must use a console-port connection to perform the initial switch configuration. When you boot the switch for the first time and the configuration file is empty, the Dell Easy Setup Wizard starts. The Dell Easy Setup Wizard is a CLI-based tool to help you perform the initial switch configuration.
Page 108 Dell recommends that you use the OOB port for remote management. The following list highlights some advantages of using OOB management instead of in-band management: •...
Page 109: Default Network Information
notification, the switch will reduce the MSS. However, many firewalls block ICMP Destination Unreachable messages, which causes the destination to request the packet again until the connection times out. In order to resolve this issue, you can reduce the MSS setting to a more appropriate value on the local host or alternatively, you can set the MTU on the PowerConnect management port to a smaller value.
Page 110: Configuring Basic Network Information (Web)

Page 128 NOTE: The terms "Master" and "Manager/Management Unit" are often used interchangeably through out this chapter. In most cases, a switch that is added to an existing stack will become a stack member, and not the Management Unit. When you add a switch to the stack, one of the following scenarios takes place regarding the management status of the new switch: •...
Page 129: Adding A Switch To The Stack
Adding a Switch to the Stack When adding a new member to a stack, make sure that only the stack cables, and no network cables, are connected before powering up the new unit. Make sure the links are not already connected to any ports of that unit. This is important because if STP is enabled and any links are UP, the STP re- convergence will take place as soon as the link is detected.
Page 130: How Is The Firmware Updated On The Stack
When a unit in the stack fails, the Master unit removes the failed unit from the stack. No changes or configuration are applied to the other stack members; however, the dynamic protocols will try to reconverge as the topology could change because of the failed unit. When there are no connected ports on the failed unit, the stack will be intact without any changes.
Page 131: What Is Nonstop Forwarding
The running-config synchronization also occurs: • when you save the running configuration to the startup configuration on the Master unit. • when the backup unit changes. What is Nonstop Forwarding? Networking devices are often described in terms of three semi-independent functions called the forwarding plane, the control plane, and the management plane.
Page 132 back-off mechanism to reduce the load on the switch. The show nsf command output includes information about when the next running-config synchronization will occur. Initiating a Failover The NSF feature allows you to initiate a failover, which causes the former Management Unit to reboot (cold start), and the new master to perform a warm restart.

Page 134: Switch Stack Mac Addressing And Stack Design Considerations
Switch Stack MAC Addressing and Stack Design Considerations The switch stack uses the MAC addresses assigned to the master unit. NOTE: Each switch is assigned three consecutive MAC addresses. The switch uses the MAC addresses for the service port, network port, and routing interfaces.
Page 135: Why Is Stacking Needed
If your switch stack performs VLAN routing, another way to take advantage of NSF is to configure multiple "best paths" to the same destination on different stack members. If a unit fails, the forwarding plane removes Equal Cost Multipath (ECMP) next hops on the failed unit from all unicast forwarding table entries.

Page 152: Nsf In The Data Center
NSF in the Data Center Figure 8-12 illustrates a data center scenario, where the stack of two PowerConnect switches acts as an access switch. The access switch is connected to two aggregation switches, AS1 and AS2. The stack has a link from two different units to each aggregation switch, with each pair of links grouped together in a LAG.
Page 153: Nsf And Voip
NSF and VoIP Figure 8-13 shows how NSF maintains existing voice calls during a Management Unit failure. Assume the top unit is the Management Unit. When the Management Unit fails, the call from phone A is immediately disconnected. The call from phone B continues. On the uplink, the forwarding plane removes the failed LAG member and continues using the remaining LAG member.
Page 154: Nsf And Dhcp Snooping
NSF and DHCP Snooping Figure 8-14 illustrates an L2 access switch running DHCP snooping. DHCP trusted snooping only accepts DHCP server messages on ports configured as ports. DHCP snooping listens to DHCP messages to build a bindings database that lists the IP address the DHCP server has assigned to each host. IP Source Guard (IPSG) uses the bindings database to filter data traffic in hardware based on source IP address and source MAC address.
Page 155: Nsf And The Storage Access Network
If a host is in the middle of an exchange with the DHCP server when the failover occurs, the exchange is interrupted while the control plane restarts. When DHCP snooping is enabled, the hardware traps all DHCP packets to the CPU. The control plane drops these packets during the restart. The DHCP client and server retransmit their DHCP messages until the control plane has resumed operation and messages get through.
Page 156 Figure 8-15. NSF and a Storage Area Network Disc Array (iSCSI Targets) Servers (iSCSI Initiators) 10.1.1.2 10.1.1.3 10.1.1.1 10.1.1.10 10.1.1.11 When the Management Unit fails, session A drops. The initiator at 10.1.1.10 detects a link down on its primary NIC and attempts to reestablish the session on its backup NIC to a different IP address on the disk array.
Page 157: Nsf And Routed Access
NSF and Routed Access Figure 8-16 shows a stack of three units serving as an access router for a set of hosts. Two LAGs connect the stack to two aggregation routers. Each LAG is a member of a VLAN routing interface. The stack has OSPF and PIM adjacencies with each of the aggregation routers.
Page 158 JOIN messages upstream. The control plane updates the driver with checkpointed unicast routes. The forwarding plane reconciles L3 hardware tables. The OSPF graceful restart finishes, and the control plane deletes any stale unicast routes not relearned at this point. The forwarding plane reconciles L3 multicast hardware tables.
Page 159: Controlling Management Access
PowerConnect 8024 and 8024F switches include several additional features to increase management security and help prevent unauthorized access to the switch configuration interfaces (CLI, Web-based, and SNMP).
Page 160 Table 9-1. Management Security Features Management Security Description Feature Management Access Contains rules to apply to one or more in-band ports, LAGs, Control List (ACL) or VLANs to limit management access by method (for example, Telnet or HTTP) and/or source IP address. NOTE: Management ACLs cannot be applied to the OOB port.
Page 161: What Are The Recommendations For Management Security
What Are the Recommendations for Management Security? Selecting the authentication policy for a network is very important. In large deployments, many administrators prefer to use a RADIUS or TACACS+ server because it allows the authentication policy to be applied system wide with little administrative effort.
Page 162: How Does Tacacs+ Control Management Access
• Console—Authenticates access through the console port (CLI only). • Telnet—Authenticates users accessing the CLI by using a Telnet or SSH client. • Secure HTTP—Authenticates users accessing OpenManage Switch Administrator by using an HTTPS connection. • HTTP—Authenticates users accessing OpenManage Switch Administrator by using an HTTP connection.
Page 163 Figure 9-1. Basic TACACS+ Topology Backup TACACS+ Server PowerConnect Switch Primary TACACS+ Server Management Network Management Host You can configure the TACACS+ server list with one or more hosts defined via their network IP address. You can also assign each a priority to determine the order in which the TACACS+ client will contact them.

How Does RADIUS Control Management Access? Many networks use a RADIUS server to maintain a centralized user database that contains per-user authentication information. RADIUS servers provide a centralized authentication method for: • Telnet Access • Web Access • Console to Switch Access •...
Page 165 Figure 9-2. RADIUS Topology Backup RADIUS Server PowerConnect Switch Primary RADIUS Server Management Network Management Host The server can authenticate the user itself or make use of a back-end device to ascertain authenticity. In either case a response may or may not be forthcoming to the client.
Page 166: What Are Radius Server Groups
NAS, from which privileged commands can be executed. What are RADIUS Server Groups? The RADIUS client on each PowerConnect 8024/8024F switch supports multiple, named RADIUS servers. When one or more configured authentication servers that share the same RADIUS server name, they form a group.
Page 167 When multiple RADIUS servers are configured with different names, the servers are in different groups. The primary/secondary designation and priority applies to RADIUS servers only within the same group. Within a named group, the switch always attempts to contact the primary RADIUS server first.
Page 168: What Other Features Use Authentication
What Other Features Use Authentication? In addition to controlling access to the management interface, the switch can use RADIUS, IAS, or the local user database to provide port-based access control. Port-based access control specifies whether devices that are connected to the switch ports are allowed access to the network. The IEEE 802.1X feature (also known as Dot1X) and Captive Portal feature use RADIUS or the local user database to control network access.

The commands in this example configure primary and secondary RADIUS servers that the switch will use to authenticate access. The RADIUS servers belong to the same named server group (Dell-RADIUS) and use the same RADIUS secret (test1234). A third RADIUS server is configured as an accounting server, and RADIUS accounting is globally enabled.

Configuring an Authentication Profile The commands in this example create a new authenticating profile that uses the RADIUS server configured in the previous example to authenticate users who attempt to access the switch management interface by using SSH or Telnet. If the RADIUS authentication is unsuccessful, the switch uses the local user database to attempt to authenticate the users.

Page 228 The password lockout feature disables local access to the switch for a given user name if the user fails to supply the correct password within the configured number of attempts. Failed attempts to log on do not need to close together in time; consecutive login failures separated by extensive time periods can still cause a user to be locked out.
Page 229 4 View information about the authentication profiles. By default, Console (serial) access uses the defaultList authentication.

Page 232: Why Is System Information Needed
Why Is System Information Needed? The information the switch provides can help you troubleshoot issues that might be affecting system performance. The cable diagnostics test help you troubleshoot problems with the physical connections to the switch. Auditing access to the switch and the activities an administrator performed while managing the switch can help provide security and accountability.
Page 233: What Are The Severity Levels
What Are the Severity Levels? For each local or remote log file, you can specify the severity of the messages to log. Each severity level is identified by a name and a number. Table 10-1 provides information about the severity levels. Table 10-1.
Page 234: What Is The Log Message Format
The first part of the log message up to the first left bracket is fixed by the Syslog standard (RFC 3164). The second part up to the two percent signs is standardized for all Dell PowerConnect logs. The variable text of the log message follows. The log message is limited to 96 bytes.
Page 235: What Factors Should Be Considered When Configuring Logging
Message — Contains the text of the log message. What Factors Should Be Considered When Configuring Logging? Dell recommends that network administrators deploy a syslog server in their network and configure all switches to log messages to the syslog server.

SNMP Configuration Examples SNMP Overview Simple Network Management Protocol (SNMP) provides a method for managing network devices. The PowerConnect 8024 and 8024F switches support SNMP version 1, SNMP version 2, and SNMP version 3. What Is SNMP? SNMP is a standard protocol that enables remote monitoring and management of a device through communication between an SNMP manager and an SNMP agent on the remote device.
Page 300: What Are Snmp Traps
The SNMP agent maintains a list of variables that are used to manage the switch. The variables are defined in the MIB. The MIB presents the variables controlled by the agent. The SNMP agent defines the MIB specification format, as well as the format used to access the information over the network. Access rights to the SNMP agent are controlled by access strings.

Page 364: Monitoring And Completing The Dhcp Auto Configuration Process
Monitoring and Completing the DHCP Auto Configuration Process When the switch boots and triggers an Auto Configuration, a message displays on the console screen to indicate that the process is starting. After the process completes, the Auto Configuration process writes a log message. When Auto Configuration has successfully completed, you can execute a show running-config command to validate the contents of configuration.
Page 365: What Are The Dependencies For Dhcp Auto Configuration
What Are the Dependencies for DHCP Auto Configuration? The Auto Configuration process from TFTP servers depends upon the following network services: • A DHCP server must be configured on the network with appropriate services. • An image file and a text file containing the image file name for the switch must be available from a TFTP server if DHCP image download is desired.
Page 366: Default Auto Configuration Values

You can specify up to eight different sFlow receivers to which the switch sends sFlow datagrams. Figure 15-1. sFlow Architecture sFlow Receiver PowerConnect Switches (sFlow Agents) sFlow Datagrams The advantages of using sFlow are: •...
Page 373 sFlow Sampling The sFlow Agent in the PowerConnect software uses two forms of sampling: • Statistical packet-based sampling of switched or routed Packet Flows • Time-based sampling of counters Packet Flow Sampling and Counter Sampling are performed by sFlow Instances associated with individual Data Sources within an sFlow Agent. Both types of samples are combined in sFlow datagrams.
Page 374: What Is Rmon
What is RMON? Like sFlow, RMON is a technology that enables the collection and analysis of a variety of data about network traffic. PowerConnect 8024/8024F switch software includes an RMON probe (also known as an RMON agent) that collect information and analyze packets. The data that is collected is defined in the RMON MIB, RFC 2819.
Page 375: What Is Port Mirroring
A port monitoring session includes one or more source ports that mirror traffic to a single destination port. The PowerConnect 8024 and 8024F switches support a single port monitoring session. LAGs (port channels) cannot be used as the source or destination ports.
Page 376: Why Is Traffic Monitoring Needed
The packet that is copied to the destination port is in the same format as the original packet on the wire. This means that if the mirror is copying a received packet, the copied packet is VLAN tagged or untagged as it was received on the source port.

Page 463: Configuring Port Characteristics
A port is a physical interface. Cables physically connect ports on devices such as PCs or servers to ports on the switch to provide access to the network. The type of physical ports available on your PowerConnect 8024/8024F switch depends on the model.
Page 464: What Is Link Dependency
Table 18-1. Port Characteristics (Continued) Feature Description Speed Specifies the transmission rate for frames. Duplex mode Specifies whether the interface supports transmission between the switch and the connected client in one direction at a time (half) or both directions simultaneously (both). Maximum frame size Indicates the maximum frame size that can be handled by the port.
Page 465 Link Action The link action specifies the action that the group members will take when the dependent port is down. The group members can transition to the same state as the dependant port, or they can transition to the opposite state. In other words, if the link action is down and the dependent port goes down, the members ports will go down as well.
Page 466: What Interface Types Are Supported
Type — For physical switch ports, the type is 10-Gibabit Ethernet (tengigabitethernet or te) for 10,000 Mbps Ethernet ports. • Stack member number— The PowerConnect 8024 and 8024F switches are standalone, non-stacking switches, so the member number is always 1. •...
Page 467 For example, to enter Interface Configuration mode for 10-Gigabit Ethernet port 10, use the following command: console(config)#interface tengigabitEthernet 1/0/10 NOTE: When you enter Interface Configuration mode, the command prompt changes and identifies the interface. In the previous example, the command prompt becomes console(config-if-Te1/0/10)# For many features, you can configure a range of interfaces.

Page 481: Configuring 802.1X And Port-Based
Configuring 802.1X and Port-Based Security This chapter describes how to configure port-based security features including IEEE 802.1X authentication and port security. Port-based security can also be accomplished by using Access Control Lists (ACLs). For information about configuring ACLs, see "Configuring Access Control Lists" on page 523.
Page 482: What Is Ieee 802.1X
Authenticator Authentication Server As shown in Figure 19-1, the PowerConnect 8024/8024F switch is the authenticator and enforces the supplicant (a PC) that is attached to an 802.1X-controlled port to be authenticated by an authentication server (a Configuring 802.1X and Port-Based Security...

RADIUS server). The result of the authentication process determines whether the supplicant is authorized to access services on that controlled port. For a list of RADIUS attributes that the switch supports, see Table 9-2 in "Controlling Management Access" on page 159 What are the 802.1X Port States? The 802.1X port state determines whether to allow or prevent network traffic on the port.
Page 484 NOTE: By default, all ports are in VLAN Access mode. A port that uses MAC- based authentication should be configured to be in General mode. When multiple hosts (for example, a PC, a printer, and a phone in the same office) are connected to the switch on the same port, each of the connected hosts authenticates separately with the RADIUS server.
Page 485: What Is The Role Of 802.1X In Vlan Assignment
What is the Role of 802.1X in VLAN Assignment? PowerConnect 8024 and 8024F switches allow a port to be placed into a particular VLAN based on the result of the authentication or type of 802.1X authentication a client uses when it accesses the switch. The authentication server can provide information to the switch about which VLAN to assign the supplicant.
Page 486 Dynamic VLAN Creation If RADIUS-assigned VLANs are enabled though the Authorization Network RADIUS configuration option, the RADIUS server is expected to include the VLAN ID in the 802.1X tunnel attributes of its response message to the switch. If dynamic VLAN creation is enabled on the switch and the RADIUS- assigned VLAN does not exist, then the assigned VLAN is dynamically created.
Page 487: What Is Monitor Mode
Guest VLAN mode can be configured on a per-port basis. If a client does not attempt authentication on a port, and the port is configured for the guest VLAN, the client is assigned to the guest VLAN configured on that port. The port is assigned a guest VLAN ID and is moved to the authorized status.

Page 515: Controlling Authentication-Based Vlan Assignment
Controlling Authentication-Based VLAN Assignment The network in this example uses three VLANs to control access to network resources. When a client connects to the network, it is assigned to a particular VLAN based on one of the following events: • It attempts to contact the 802.1X server and is authenticated.
Page 516 To configure the switch: 1 Create the VLANs and configure the VLAN names. console(config)#vlan 100 console(config-vlan100)#name Authorized console(config-vlan100)#exit console(config)#vlan 200 console(config-vlan200)#name Unauthorized console(config-vlan200)#exit console(config)#vlan 300 console(config-vlan300)#name Guest console(config-vlan300)#exit 2 Configure information about the external RADIUS server the switch uses to authenticate clients. The RADIUS server IP address is 10.10.10.10, and the shared secret is qwerty123.
Page 517 8 Enable periodic reauthentication of the client on the ports and set the number of seconds to wait between reauthentication attempts to 300 seconds. Reauthentication is enabled to increase security. If the client information is removed from the RADIUS server after it has been authenticated, the client will be denied access when it attempts to reauthenticate.
Page 518: Allowing Dynamic Vlan Creation Of Radius-Assigned Vlans
Allowing Dynamic VLAN Creation of RADIUS-Assigned VLANs The network in this example uses a RADIUS server to provide VLAN assignments to host that connect to the switch. In this example, the VLANs are not configured on the switch. Instead, the switch is configured to allow the dynamic creation of VLANs when a RADIUS-assigned VLAN does not already exist on the switch.
Page 519 5 Allow the switch to dynamically create VLANs when a RADIUS-assigned VLAN does not exist on the switch. console(config)#dot1x dynamic-vlan enable 6 Enter interface configuration mode for the downlink ports. console(config)#interface range te1/0/1-23 7 Set the downlink ports to the access mode because each downlink port connects to a single host that belongs to a single VLAN.

Page 523: Configuring Access Control Lists
Layer 3 switch, such as a PowerConnect 8024/8024F switch. The PowerConnect 8024 and 8024F switches support ACL configuration in both the ingress and egress direction. Egress ACLs provide the capability to implement security rules on the egress flows (traffic leaving a port) rather than the ingress flows (traffic entering a port).
Page 524: What Are Mac Acls
NOTE: Every ACL is terminated by an implicit deny all rule, which covers any packet not matching a preceding explicit rule. You can set up ACLs to control traffic at Layer 2, Layer 3, or Layer 4. MAC ACLs operate on Layer 2. IP ACLs operate on Layers 3 and 4. PowerConnect 8024 and 8024F switches support both IPv4 and IPv6 ACLs.
Page 525: What Are Ip Acls
What Are IP ACLs? IP ACLs classify for Layers 3 and 4 on IPv4 or IPv6 traffic. Each ACL is a set of up to ten rules applied to inbound traffic. Each rule specifies whether the contents of a given field should be used to permit or deny access to the network, and may apply to one or more of the following fields within a packet: •...

• The PowerConnect 8024 and 8024F switches support a limited number of counter resources, so it may not be possible to log every ACL rule. You can define an ACL with any number of logging rules, but the number of rules that are actually logged cannot be determined until the ACL is applied to an interface.
Page 528: How Are Acls Configured
NOTE: Although the maximum number of ACLs is 100, and the maximum number of rules per ACL is 127, the system cannot support 100 ACLs that each have 127 rules. The maximum number of ACLs and rules supported depends on the resources consumed by other processes and configured features running on the switch.

Page 560: Switchport Modes
VLANs, you can segregate traffic based on the EtherType value in the frame. Switchport Modes You can configure each port on a PowerConnect 8024/8024F switch to be in one of the following modes: • Access — Access ports are intended to connect end-stations to the system, especially when the end-stations are incapable of generating VLAN tags.
Page 561: Vlan Tagging
VLAN Tagging PowerConnect 8024 and 8024F switches support IEEE 802.1Q tagging. Ethernet frames on a tagged VLAN have a 4-byte VLAN tag in the header. VLAN tagging is required when a VLAN spans multiple switches, which is why trunk ports transmit and receive only tagged frames.
Page 562: Gvrp
Double-VLAN Tagging For trunk ports, which are ports that connect one switch to another switch, the PowerConnect 8024 and 8024F switches support double-VLAN tagging. This feature allows service providers to create Virtual Metropolitan Area Networks (VMANs). With double-VLAN tagging, service providers can pass VLAN traffic from one customer domain to another through a metro core in a simple and cost-effective manner.

Page 564 Identifying Voice Traffic Some VoIP phones contain full support for IEEE 802.1X. When these phones are connected to a port that uses 802.1X port-based authentication, these phones authenticate and receive their VLAN information from LLDP-MED. However, if a VoIP phone has limited support for 802.1X authentication it might try to authenticate and fail.
Page 565: Additional Vlan Features
The Voice VLAN component interacts with LLDP-MED for applying VLAN ID, priority, and tag information to the VoIP phone traffic.

Page 566: Default Vlan Behavior
Default VLAN Behavior One VLAN exists on the PowerConnect 8024 and 8024F switches by default. The VLAN ID is 1, and all ports are included in the VLAN as access ports, which are untagged. This means when a device connects to any port on the switch, the port forwards the packets without inserting a VLAN tag.

STP uses the spanning-tree algorithm to provide a single path between end stations on a network. PowerConnect 8024 and 8024F switches support Classic STP , Multiple STP , and Rapid STP. What Are Classic STP, Multiple STP, and Rapid STP? Classic STP provides a single path between end stations, avoiding and eliminating loops.

recognize full-duplex connectivity and ports which are connected to end stations, resulting in rapid transitioning of the port to the Forwarding state and the suppression of Topology Change Notifications. MSTP is compatible to both RSTP and STP . It behaves appropriately to STP and RSTP bridges.
Page 617: How Does Mstp Operate In The Network
How Does MSTP Operate in the Network? In the following diagram of a small 802.1d bridged network, STP is necessary to create an environment with full connectivity and without loops. Figure 22-1. Small Bridged Network Switch A Port 1 Port 2 VLAN 10 VLAN 20 Port 1...
Page 618 Figure 22-2 shows the logical single STP network topology. Figure 22-2. Single STP Topology Switch A Port 1 Port 2 VLAN 10 VLAN 20 Port 1 Port 1 Switch B Switch C VLAN 10 VLAN 20 VLAN 20 For VLAN 10 this single STP topology is fine and presents no limitations or inefficiencies.
Page 619 The logical representation of the MSTP environment for these three switches is shown in Figure 22-3. Figure 22-3. Logical MSTP Environment MSTI 1 Regional Root & CIST Regional Root Switch A MSTI 1 Port 1 Port 2 VLAN 10 Port 1 Port 1 Switch B Switch C...
Page 620 In order for MSTP to correctly establish the different MSTIs as above, some additional changes are required. For example, the configuration would have to be the same on each and every bridge. That means that Switch B would have to add VLAN 10 to its list of supported VLANs (shown in Figure 22-3 with a *).
Page 621: What Are The Optional Stp Features
What are the Optional STP Features? The PowerConnect 8024 and 8024F switches support the following optional STP features: • BPDU flooding • PortFast • BPDU filtering • Root guard • Loop guard • BPDU protection BPDU Flooding The BPDU flooding feature determines the behavior of the switch when it receives a BPDU on a port that is disabled for spanning tree.
Page 622 Root Guard Enabling root guard on a port ensures that the port does not become a root port or a blocked port. When a switch is elected as the root bridge, all ports are designated ports unless two or more ports of the root bridge are connected together.
Page 623 BPDU Protection When the switch is used as an access layer device, most ports function as edge ports that connect to a device such as a desktop computer or file server. The port has a single, direct connection and is configured as an edge port to implement the fast transition to a forwarding state.

Page 675: Configuring Port-Based Traffic
Configuring Port-Based Traffic Control This chapter describes how to configure features that provide traffic control through filtering the type of traffic or limiting the speed or amount of traffic on a per-port basis. The features this section describes includes flow control, storm control, protected ports, and Link Local Protocol Filtering (LLPF), which is also known as Cisco Protocol Filtering.
Page 676: What Is Flow Control
Transmissions are temporarily halted to prevent buffer overflows. Enabling the flow control feature allows PowerConnect 8024 and 8024F switches to process pause frames received from connected devices. PowerConnect switches do not transmit pause frames.
Page 677: What Are Protected Ports
configured limit is 10%, this is converted to ~25000 PPS, and this PPS limit is set in the hardware. You get the approximate desired output when 512 bytes packets are used. What are Protected Ports? The switch supports up to three separate groups of protected ports. Traffic can flow between protected ports belonging to different groups, but not within the same group.
Page 678: Default Port-Based Traffic Control Values
Access Control Lists (ACLs) and LLPF can exist on the same interface. However, the ACL rules override the LLPF rules when there is a conflict. Similarly, DiffServ and LLPF can both be enabled on an interface, but DiffServ rules override LLPF rules when there is a conflict. If Industry Standard Discovery Protocol (ISDP) is enabled on an interface, and the LLPF feature on an interface is enabled and configured to drop ISDP PDUs, the ISDP configuration overrides the LLPF configuration, and the...

Page 691: Configuring L2 Multicast Features
IP multicast traffic by keeping track of multicast group membership. What Are the Multicast Bridging Features? The PowerConnect 8024 and 8024F switches support bridge multicast filtering and bridge multicast forwarding. For Ethernet multicast traffic, the switch uses a database called the Layer 2 Multicast Forwarding Database (MFDB) to make forwarding decisions for packets that arrive with a multicast destination MAC address.
Page 692: What Is Ip Multicast Traffic
discarded, depending on the switch configuration. If a match is found, then the packet is forwarded only to the ports that are members of that multicast group. You can create multicast bridging groups and specify the ports and LAGs that are members of each group.
Page 693: What Is Igmp Snooping
What Is IGMP Snooping? IGMP Snooping is a layer 2 feature that allows the switch to dynamically add or remove ports from IP multicast groups by listening to IGMP join and leave requests. By "snooping" the IGMP packets transmitted between hosts and routers, the IGMP Snooping feature enables the switch to forward IP multicast traffic more intelligently and help conserve bandwidth.
Page 694: What Is Multicast Vlan Registration
MLD is a protocol used by IPv6 multicast routers to discover the presence of multicast listeners (nodes wishing to receive IPv6 multicast packets) on its directly-attached links and to discover which multicast packets are of interest to neighboring nodes. MLD is derived from IGMP; MLD version 1 (MLDv1) is equivalent to IGMPv2, and MLD version 2 (MLDv2) is equivalent to IGMPv3.
Page 695: When Are L3 Multicast Features Required
If MVR is enabled, IP Multicast should be disabled. Multicast routing and MVR cannot coexist on a switch.

Page 743: L2 Multicast Configuration Examples
L2 Multicast Configuration Examples This section contains the following examples: • Configuring IGMP Snooping • Configuring MVR Configuring IGMP Snooping This example configures IGMP snooping on the switch to limit multicast traffic and to allow L2 multicast forwarding on a single VLAN. The IP- multicast traffic in VLAN 100 needs to be Layer 2 switched only, so the IGMP snooping querier is enabled on the switch to perform the IGMP snooping functions on the VLAN, if necessary.
Page 744 To configure the switch: 1 Enable IGMP snooping globally. console(config)#ip igmp snooping 2 Enable the IGMP snooping querier on the switch. If there are no other IGMP snooping queriers, this switch will become the IGMP snooping querier for the local network. If an external querier is discovered, this switch will not be a querier.

After performing the configuration in this example, Host A sends a join message for multicast group 225.1.1.1. Host B sends a join message for group 225.1.1.2. Because IGMP snooping is enabled on the switch and on VLAN 100, the switch listens to the messages and dynamically adds Ports 1 and 2 to the multicast address table.

Page 752: What Is Dhcp Snooping
What Is DHCP Snooping? Dynamic Host Configuration Protocol (DHCP) Snooping is a security feature that monitors DHCP messages between a DHCP client and DHCP server to accomplish the following tasks: • Filter harmful DHCP messages • Build a bindings database with entries that consist of the following information: •...
Page 753: How Is The Dhcp Snooping Bindings Database Populated
How Is the DHCP Snooping Bindings Database Populated? The DHCP snooping application uses DHCP messages to build and maintain the binding’s database. DHCP snooping creates a tentative binding from DHCP DISCOVER and REQUEST messages. Tentative bindings tie a client to a port (the port where the DHCP client message was received). Tentative bindings are completed when DHCP snooping learns the client’s IP address from a DHCP ACK message on a trusted port.
Page 754 DHCP Snooping and VLANs DHCP snooping forwards valid DHCP client messages received on non- routing VLANs. The message is forwarded on all trusted interfaces in the VLAN. DHCP snooping can be configured on switching VLANs and routing VLANs. When a DHCP packet is received on a routing VLAN, the DHCP snooping application applies its filtering rules and updates the bindings database.
Page 755: What Is Ip Source Guard
What Is IP Source Guard? IPSG is a security feature that filters IP packets based on source ID. This feature helps protect the network from attacks that use IP address spoofing to compromise or overwhelm the network. The source ID may be either the source IP address or a {source IP address, source MAC address} pair.
Page 756: What Is Dynamic Arp Inspection
What is Dynamic ARP Inspection? Dynamic ARP Inspection (DAI) is a security feature that rejects invalid and malicious ARP packets. DAI prevents a class of man-in-the-middle attacks where an unfriendly station intercepts traffic for other stations by poisoning the ARP caches of its unsuspecting neighbors. The malicious attacker sends ARP requests or responses mapping another station’s IP address to its own MAC address.
Page 757: Why Is Traffic Snooping And Inspection Necessary
Why Is Traffic Snooping and Inspection Necessary? DHCP Snooping, IPSG, and DAI are security features that can help protect the switch and the network against various types of accidental or malicious attacks. It might be a good idea to enable these features on ports that provide network access to hosts that are in physically unsecured locations or if network users connect nonstandard hosts to the network.

Page 789: Configuring Link Aggregation
8 interfaces per dynamic LAG. For example, 72 LAGs may be assigned 2 interfaces each, or 18 LAGs may be assigned 8 interfaces each. Each PowerConnect 8024/8024F switch supports a maximum of 7 static or dynamic LAGs. Each LAG can consist of up to eight 10 Gbps ports. When eight 10 Gbps ports are configured as a LAG, the maximum bandwidth for the single, logical interface is 80 Gbps.
Page 790: Why Are Link Aggregation Groups Necessary
IEEE 802.3ad standard, which is known as Link Aggregation Control Protocol (LACP). Static configuration is used when connecting a PowerConnect 8024/8024F switch to an external Gigabit Ethernet switch that does not support LACP . One advantage of LACP is that the protocol enables the switch to confirm that the external switch is also configured for link aggregation.
Page 791: What Is Lag Hashing
LACP PDUs. What is LAG Hashing? PowerConnect 8024 and 8024F switches support configuration of hashing algorithms for each LAG interface. The hashing algorithm is used to distribute traffic load among the physical ports of the LAG while preserving the per-flow packet order.
Page 792: How Do Lags Interact With Other Features
How Do LAGs Interact with Other Features? From a system perspective, a LAG is treated just as a physical port, with the same configuration parameters for administrative enable/disable, spanning tree port priority, path cost as may be for any other physical port. VLAN When members are added to a LAG, they are removed from all existing VLAN membership.

Page 807: Configuring Data Center Features
• Data Center Bridging Configuration Examples Data Center Technology Overview The PowerConnect 8024/8024F switches support Data Center Bridging (DCB) features to increase the reliability of Ethernet-based networks in the data center. The Ethernet enhancements that DCB provides are well suited for Fibre Channel over Ethernet (FCoE) environments and iSCSI applications.
Page 808: What Is Priority-Based Flow Control
Table 28-1. Data Center Features (Continued) Feature Description DCBX Allows DCB devices to exchange configuration information, using type-length-value (TLV) information elements over LLDP, with directly connected peers. Supports the ETS configuration and Application Priority TLVs, which are accepted from auto-upstream devices and propagated to auto-downstream devices.
Page 809 PFC Operation and Behavior PFC uses a new control packet defined in IEEE 802.1Qbb and therefore is not compatible with IEEE 802.3 Annex 31B flow control. An interface that is configured for PFC will be automatically disabled for flow control. When PFC is disabled on an interface, the flow control configuration for the interface becomes active.
Page 810: What Is The Data Center Bridging Exchange Protocol
What Is the Data Center Bridging Exchange Protocol? The Data Center Bridging Exchange Protocol (DCBX) is used by DCB devices to exchange configuration information with directly connected peers. DCBX uses type-length-value (TLV) information elements over LLDP to exchange information, so LLDP must be enabled on the port to enable the information exchange.
Page 811 Interoperability with IEEE DCBX To be interoperable with legacy industry implementations of DCBX protocol, The PowerConnect 8024/8024F switches use a hybrid model to support both the IEEE version of DCBX (IEEE 802.1Qaz) and legacy DCBX versions. The PowerConnect 8024/8024F switch automatically detects if a peer is operating with either of the two CEE DCBX versions or the IEEE standard DCBX version.
Page 812 The default operating mode for each port is manual. A port that is set to manual mode sets the willing bit for DCBX client TLVs to false. Manually- configured ports never internally propagate or accept internal or external configuration from other ports, in other words, a manual configuration discards any automatic configuration.
Page 813 local configuration and utilize the internally propagated information. Auto- downstream ports propagate PFC, ETS, and application priority information received from the configuration source. In the Configuration Source role, the port has been manually selected to be the configuration source. Configuration received over this port is propagated to the other auto-configuration ports, however, no automatic election of a new configuration source port is allowed.
Page 814: What Is Enhanced Transmission Selection
Enhanced Transmission Selection (ETS) enables the sharing and redistribution of network bandwidth between various protocols. To support ETS, PowerConnect 8024/8024F switches accept the ETS traffic class group and bandwidth information Application Priority TLV from auto-upstream devices and propagate it to auto-downstream devices. In addition, if iSCSI CoS is enabled, an additional entry in the Application Priority TLV is added.

NOTE: The PowerConnect 8024/8024F FIP Snooping Bridge feature supports the configuration of the perimeter port role and FCF-facing port roles and is intended for use only at the edge of the switched network.
Page 816 FCF facing interface. Dell recommends that FCF-facing ports be placed into auto-upstream mode in order to receive DCBX information and propagate it to the Converged Network Adaptors (CNAs) on the downstream ports. Interfaces enabled for PFC should be configured in trunk or general mode and must be PFC operationally enabled before FCoE traffic can pass over the port.

What Information Is in the MAC Address Table? Each entry in the address table, whether it is static or dynamic, includes the MAC address, the VLAN ID associated with the MAC address, and the interface on which the address was learned or configured. Each port can maintain multiple MAC addresses, and a MAC address can be associated with multiple VLANs.

Page 835: Configuring Routing Interfaces
VLANs divide a single physical network (broadcast domain) into separate logical networks. To forward traffic across VLAN boundaries, a layer 3 device, such as router, is required. PowerConnect 8024 and 8024F switches can act as layer 3 devices when you configure VLAN routing interfaces. VLAN routing interfaces make it possible to transmit traffic between VLANs while still containing broadcast traffic within VLAN boundaries.
Page 836: What Are Loopback Interfaces
For each VLAN routing interface you can assign a static IP address, or you can allow a network DHCP server to assign a dynamic IP address. When a port is enabled for bridging (L2 switching) rather than routing, which is the default, all normal bridge processing is performed for an inbound packet, which is then associated with a VLAN.
Page 837: What Are Tunnel Interfaces
The packet is in an incompatible addressing space. • The packet is encrypted. PowerConnect 8024 and 8024F switches support tunnels to encapsulate IPv6 traffic in IPv4 tunnels to provide functionality to facilitate the transition of IPv4 networks to IPv6 networks.
Page 838: Why Are Routing Interfaces Needed
Why Are Routing Interfaces Needed? The routing interfaces this chapter describes have very different applications and uses, as this section describes. If you use the switch as a layer 2 device that handles switching only, routing interface configuration is not required. When the switch is used as a layer 2 device, it typically connects to an external layer 3 device that handles the routing functions.
Page 839 Loopback Interfaces When packets are sent to the loopback IP address, the network should be able to deliver the packets as long as any physical interface on the switch is up. There are many cases where you need to send traffic to a switch, such as in switch management.
Page 840: Default Routing Interface Values
Default Routing Interface Values By default, no routing interfaces are configured. When you create a VLAN, no IP address is configured, and DHCP is disabled. After you configure an IP address, routing is automatically enabled on the interface, and the interface has the default configuration shown in Table 30-1.

Page 923: Configuring Ospf And Ospfv3
Configuring OSPF and OSPFv3 This chapter describes how to configure Open Shortest Path First (OSPF) and OSPFv3. OSPF is a dynamic routing protocol for IPv4 networks, and OSPFv3 is used to route traffic in IPv6 networks. The protocols are configured separately within the software, but their functionality is largely similar for IPv4 and IPv6 networks.
Page 924: Ospf Overview
OSPF Overview OSPF is an Interior Gateway Protocol (IGP) that performs dynamic routing within a network. PowerConnect 8024 and 8024F switches support two dynamic routing protocols: OSPF and Routing Information Protocol (RIP). Unlike RIP , OSPF is a link-state protocol. Larger networks typically use the OSPF protocol instead of RIP.
Page 925: What Are Ospf Routers And Lsas
What Are OSPF Routers and LSAs? When a PowerConnect switch is configured to use OSPF for dynamic routing, it is considered to be an OSPF router. OSPF routers keep track of the state of the various links they send data to. Routers exchange OSPF link state advertisements (LSAs) with other routers.
Page 926: Default Ospf Values
Default OSPF Values OSPF is globally enabled by default. To make it operational on the router, you must configure a router ID and enable OSPF on at least one interface. Table 34-1 shows the global default values for OSPF and OSPFv3. Table 34-1.
Page 927 Table 34-2 shows the per-interface default values for OSPF and OSPFv3. Table 34-2.
