Page 30: Connecting The Console Port (Rs-232 Dce)
xStack DGS-3400 Series Fast Ethernet Switch Connecting the Console Port (RS-232 DCE) The Switch provides an RS-232 serial port that enables a connection to a computer or terminal for monitoring and configuring the Switch. This port is a female DB-9 connector, implemented as a data terminal equipment (DTE) connection.
Page 31: Managing The Switch For The First Time
Upon the initial connection, there is no user name or password and therefore just press enter twice to access the command line interface. Figure 4- 1. Boot up display in console screen (DGS-3427) Managing the Switch for the First Time The Switch supports user-based security that can allow prevention of unauthorized users from accessing the Switch or changing its settings.

Page 33: Password Protection
xStack DGS-3400 Series Fast Ethernet Switch Password Protection The xStack DGS-3400 Series switches do not have a default user name and password. One of the first tasks when settings up the Switch is to create user accounts. Logging in using a predefined administrator-level user name will give the user privileged access to the Switch's management software.
Page 34 xStack DGS-3400 Series Fast Ethernet Switch SNMP Settings Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches and other network devices.
Page 35: Ip Address Assignment
xStack DGS-3400 Series Fast Ethernet Switch IP Address Assignment An IP Address must be assigned to each switch, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch's default IP address is 0.0.00 (i.e. no default IP address).
Page 36 xStack DGS-3400 Series Fast Ethernet Switch Figure 4- 5. Assigning the Switch an IP Address In the above example, the Switch was assigned an IP address of 10.34.27.100 with a subnet mask of 255.0.0.0.

Page 57: Tftp Services
xStack DGS-3400 Series Fast Ethernet Switch TFTP Services Trivial File Transfer Protocol (TFTP) services allow the Switch's firmware to be upgraded by transferring a new firmware file from a TFTP server to the Switch. A configuration file can also be loaded into the Switch from a TFTP server. Switch configuration settings can be saved to the TFTP server, and a history log can be uploaded from the Switch to the TFTP server.
Page 58: Multiple Image Services
xStack DGS-3400 Series Fast Ethernet Switch Multiple Image Services The Multiple Image Services folder allows users of the Switch to configure and view information regarding firmware located on the Switch. The Switch allows two firmware images to be stored in its memory and either can be configured to be the boot up firmware for the Switch.
Page 59: Ping Test
xStack DGS-3400 Series Fast Ethernet Switch Ping Test Ping is a small program that sends ICMP Echo packets to the IP address you specify. The destination node then responds to or "echoes" the packets sent from the Switch. This is very useful to verify connectivity between the Switch and other nodes on the network.
Page 60 xStack DGS-3400 Series Fast Ethernet Switch IP packets may also be limited by the Switch by configuring only certain IP addresses to be accepted. This method can be accomplished through the CPU Interface Filtering mechanism explained in the previous section. Once the user configures these acceptable IP addresses, other packets containing different IP addresses will be dropped by the Switch, thus limiting the bandwidth of IP packets.

xStack DGS-3400 Series Fast Ethernet Switch Section 7 Layer 2 Features VLANs Trunking IGMP Snooping Spanning Tree Forwarding and Filtering The following section will aid the user in configuring security functions for the Switch. The Switch includes various functions for VLAN, Trunking, IGMP Snooping, Spanning Tree, and Forwarding, all discussed in detail in the following section.
Page 92: Notes About Vlans On The Dgs-3400 Series
xStack DGS-3400 Series Fast Ethernet Switch A VLAN is a collection of end nodes grouped by logic instead of physical location. End nodes that frequently communicate with each other are assigned to the same VLAN, regardless of where they are physically on the network. Logically, a VLAN can be equated to a broadcast domain, because broadcast packets are forwarded to only members of the VLAN on which the broadcast was initiated.
Page 93: 802.1Q Vlan Tags
xStack DGS-3400 Series Fast Ethernet Switch Figure 7- 1. IEEE 802.1Q Packet Forwarding 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the EtherType field. When a packet's EtherType field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
Page 94: Port Vlan Id
xStack DGS-3400 Series Fast Ethernet Switch The EtherType and VLAN ID are inserted after the MAC source address, but before the original EtherType/Length or Logical Link Control. Because the packet is now a bit longer than it was originally, the Cyclic Redundancy Check (CRC) must be recalculated.

Ports with untagging enabled will strip the 802.1Q tag from all packets that flow into and out of those ports. If the packet doesn't have an 802.1Q VLAN tag, the port will not alter the packet.
Page 96: Port-Based Vlans
xStack DGS-3400 Series Fast Ethernet Switch Port-based VLANs Port-based VLANs limit traffic that flows into and out of switch ports. Thus, all devices connected to a port are members of the VLAN(s) the port belongs to, whether there is a single computer directly connected to a switch, or an entire department.

Page 101: Trunking
xStack DGS-3400 Series Fast Ethernet Switch Trunking Understanding Port Trunk Groups Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline. DGS- 3400 Series supports up to 32 port trunk groups with 2 to 8 ports in each group. A potential bit rate of 8000 Mbps can be achieved.
Page 102: Link Aggregation
xStack DGS-3400 Series Fast Ethernet Switch Load balancing is automatically applied to the ports in the aggregated group, and a link failure within the group causes the network traffic to be directed to the remaining links in the group. The Spanning Tree Protocol will treat a link aggregation group as a single link, on the switch level. On the port level, the STP will use the port parameters of the Master Port in the calculation of port cost and in determining the state of the link aggregation group.
Page 103 xStack DGS-3400 Series Fast Ethernet Switch Figure 7- 11. Link Aggregation Settings window - Modify The user-changeable parameters are as follows: Parameter Description Group ID Select an ID number for the group, between 1 and 32.

Page 123: Qos
xStack DGS-3400 Series Fast Ethernet Switch The xStack DGS-3400 switch series supports 802.1p priority queuing Quality of Service. The following section discusses the implementation of QoS (Quality of Service) and benefits of using 802.1p priority queuing. The Advantages of QoS QoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving bandwidth for important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over Internet Protocol), web browsing applications, file server applications or video conferencing.
Page 124: Understanding Qos
xStack DGS-3400 Series Fast Ethernet Switch Understanding QoS The DGS-3400 Series supports 802.1p priority queuing. The Switch has 8 priority queues. These priority queues are numbered from 7 (Class 6) — the highest priority queue — to 0 (Class 0) — the lowest priority queue. The eight priority tags specified in IEEE 802.1p (p0 to p7) are mapped to the Switch’s priority queues as follows: •...
