Page 35: Notes On Stacking Switches
D-Link DES-3326S Layer 3 Switch Notes on Stacking Switches By default, the Switch configuration settings allow it to operate as a standalone device, or in a stacked group. It is not necessary to change any settings for the Switch to function in either capacity. However, it is recommended that a Master Switch be manually designated for a stacked group when it is first set up.
Page 36: Configuring A Switch Group For Stacking
D-Link DES-3326S Layer 3 Switch Configuring a Switch Group for Stacking In order to set up a stack of DES-3326S Switches it is only necessary to designate a single Switch as Master if all the Switches are using the default auto setting for the stacking mode configuration. Stacking mode may also be disabled for standalone operation, however it is not necessary to disable stacking to use the Switch as a standalone device.
Page 37 D-Link DES-3326S Layer 3 Switch Figure 2 - 9. config stacking mode enable master The remaining slave units in the stack can be set to the default configuration to automatically recognize the presence of the Master. The stack order will likewise be determined automatically according to the physical stacking connection.
Page 38: Notes On Standalone Operation
D-Link DES-3326S Layer 3 Switch Notes on Standalone Operation The DES-3326S operates as a standalone Switch using the default configuration settings when it is not connected to another Switch through a stacking port. It may also be configured to disable stacking for the Switch, in which case, if a stacking module is installed, the stacking port should not be used.

D-Link DES-3326S Layer 3 Switch Chapter 18 VLAN IP I S AND NTERFACES VLANs can function somewhat differently in a Layer 3 Switch, that is when the VLANs are Layer 3-based, than if they are strictly based on Layer 2 information. Since IP Switching among VLANs may be unfamiliar to users who are otherwise well acquainted with conventional VLANs used in standard Ethernet Switches, some explanation of VLANs used in Layer 3 Switching is presented below.
Page 144 D-Link DES-3326S Layer 3 Switch VLAN can be equated to a broadcast domain, because broadcast packets are forwarded only to members of the VLAN on which the broadcast was initiated. IEEE 802.1Q VLANs Some relevant terms: Tagging - The act of putting 802.1Q VLAN information into the header of a packet.
Page 145 D-Link DES-3326S Layer 3 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.
Page 146: Ingress Filtering
D-Link DES-3326S Layer 3 Switch Switch will drop the packet. Because of the existence of the PVID for untagged packets and the VID for tagged packets, tag- aware and tag-unaware network devices can coexist on the same network. A Switch port can have only one PVID, but can have as many VIDs as the Switch has memory in its VLAN table to store them.

Page 167: Introduction To Ospf
D-Link DES-3326S Layer 3 Switch Chapter 22 Introduction to OSPF The Open Shortest Path First (OSPF) routing protocol that uses a link-state algorithm to determine routes to network destinations. A “link” is an interface on a router and the “state” is a description of that interface and its relationship to neighboring routers.
Page 168 D-Link DES-3326S Layer 3 Switch OSPF Cost Each OSPF interface has an associated cost (also called “metric”) that is representative of the overhead required to send packets over that interface. This cost is inversely proportional to the bandwidth of the interface (i.e. a higher bandwidth interface has a lower cost).
Page 169 D-Link DES-3326S Layer 3 Switch Router A 128.213.0.0 Router B Router C 192.213.11.0 Router D 222.211.10.0 Figure 23- 2. Constructing a Shortest Path Tree The diagram above shows the network from the viewpoint of Router A. Router A can reach 192.213.11.0 through Router B with a cost of 10+5=15.
Page 170 D-Link DES-3326S Layer 3 Switch Areas and Border Routers OSPF link-state updates are forwarded to other routers by flooding to all routers on the network. OSPF uses the concept of areas to define where on the network routers that need to receive particular link-state updates are located. This helps ensure that routing updates are not flooded throughout the entire network and to reduce the amount of bandwidth consumed by updating the various router’s routing tables.
Page 171 D-Link DES-3326S Layer 3 Switch OSPF Authentication OSPF packets can be authenticated as coming from trusted routers by the use of predefined passwords. The default for routers is to use not authentication. There are two other authentication methods − simple password authentication (key) and Message Digest authentication (MD- Message Digest Authentication (MD-5) MD-5 authentication is a cryptographic method.
Page 172 D-Link DES-3326S Layer 3 Switch Neighbors Routers that are connected to the same area or segment become neighbors in that area. Neighbors are elected via the Hello protocol. IP multicast is used to send out Hello packets to other routers on the segment. Routers become neighbors when they see themselves listed in a Hello packet sent by another router on the same segment.

Page 178 D-Link DES-3326S Layer 3 Switch The Link-State Acknowledgment Packet Link-State Acknowledgment packets are OSPF packet type 5. To make the folding of link-state advertisements reliable, flooded advertisements are explicitly acknowledged. This acknowledgment is accomplished through the sending and receiving of Link-State Acknowledgment packets. Multiple link-state advertisements can be acknowledged in a single Link-State Acknowledgment packet.
Page 179 D-Link DES-3326S Layer 3 Switch recent. This is accomplished by examining the link state age, link state sequence number and link state checksum fields that are also contained in the link state advertisement header. The format of the Link State Advertisement Header is shown below:...
Page 180 D-Link DES-3326S Layer 3 Switch Router Links Advertisements Router links advertisements are type 1 link state advertisements. Each router in an area originates a routers links advertisement. The advertisement describes the state and cost of the router’s links to the area. All of the router’s links to the area must be described in a single router links advertisement.
Page 181 D-Link DES-3326S Layer 3 Switch Field Description A quick classification of the router link. One of the following: Type Description Point-to-point connection to another router. Type Connection to a transit network. Connection to a stub network. Virtual link. Identifies the object that this router link connects to.
Page 182 D-Link DES-3326S Layer 3 Switch Network Links Advertisements Network links advertisements are Type 2 link state advertisements. A network links advertisement is originated for each transit network in the area. A transit network is a multi-access network that has more than one attached router. The network links advertisement is originated by the network’s Designated router.

Page 184 D-Link DES-3326S Layer 3 Switch Autonomous Systems External Link Advertisements Autonomous Systems (AS) link advertisements are Type 5 link state advertisements. These advertisements are originated by AS boundary routers. A separate advertisement is made for each destination known to the router, that is external to the AS.

Page 186: Md5 Key Table Configuration
D-Link DES-3326S Layer 3 Switch MD5 Key Table Configuration MD5 authentication is used to identify trusted routers sending OSPF packets. By default no authentication is used for OSPF so it is not necessary to configure any MD5 keys to use OSPF. MD5 authentication can be set up at any time, before or after you have configured OSPF settings.
Page 187: Configure Ospf Settings
D-Link DES-3326S Layer 3 Switch Configure OSPF Settings All the links for OSPF configuration menus are contained within a subdirectory of the Layer 3 IP Networking subdirectory (located in the Configuration folder). The OSPF tables used to monitor OSPF information can be accessed using the links located in the OSPF subdirectory located in the Layer 3 subdirectory of the Monitoring folder.
Page 188 D-Link DES-3326S Layer 3 Switch To set up an OSPF Area configuration click the OSPF Area Settings link to open the following dialog box: Figure 24- 5. OSPF Area Setting The first OSPF Area Setting screen displays a summary of all of the OSPF areas defined on the switch. OSPF areas can be added, edited, or deleted from this screen.
Page 189: Ospf Interface Configuration
D-Link DES-3326S Layer 3 Switch OSPF Interface Configuration To set up OSPF interfaces, click the OSPF Interface Settings link to view OSPF settings for existing IP interfaces. If there are no IP interfaces configured (besides the default System interface), only the System interface settings will appear listed.

Virtual Interface Configuration − Add Configure the following parameters if you are adding or changing an OSPF Virtual Interface: Parameter Description Allows the entry of an OSPF Area ID − previously defined on the Switch − that allows a Transit Area ID remote area to communicate with the backbone (area 0).
Page 192: Area Aggregation Configuration
D-Link DES-3326S Layer 3 Switch Area Aggregation Configuration Area Aggregation allows all of the routing information that may be contained within an area to be aggregated into a summary LSDB advertisement of just the network address and subnet mask. This allows for a reduction in the volume of LSDB advertisement traffic as well as a reduction in the memory overhead in the Switch used to maintain routing tables.
Page 193: Ospf Host Route Settings
D-Link DES-3326S Layer 3 Switch OSPF Host Route Settings OSPF host routes work in a way analogous to RIP, only this is used to share OSPF information with other OSPF routers. This is used to work around problems that might prevent OSPF information sharing between routers.
Page 194: Route Redistribution Settings
D-Link DES-3326S Layer 3 Switch Route Redistribution Settings Route redistribution allows routers on the network − that are running different routing protocols − to exchange routing information. This is accomplished by comparing the routes stored in the various router’s routing tables and assigning appropriate metrics.

Page 203: Internet Protocols
D-Link DES-3326S Layer 3 Switch Internet Protocols This is a brief introduction to the suite of Internet Protocols frequently referred to as TCP/IP. It is intended to give the reader a reasonable understanding of the available facilities and some familiarity with terminology. It is not intended to be a complete description.
Page 204 D-Link DES-3326S Layer 3 Switch Figure B- 2. The Protocol Stack Between two protocol stacks, members of the same layer are known as peers and communicate by well-known (open and published) protocols. Within a protocol stack, adjacent layers communicate by an internal interface. This interface is usually not publicly documented and is frequently proprietary.
Page 205: Packet Headers
D-Link DES-3326S Layer 3 Switch Layer 4 This layer, known as the transport layer, establishes the communication path between user applications and the network infrastructure and defines the method of communicating. TCP and UDP are well-known protocols in the transport layer.
Page 206 D-Link DES-3326S Layer 3 Switch The TCP header contains at least 20 octets. The source and destination TCP port numbers are the most important fields. These specify the connection between two TCP protocols on two network devices. The header also contains a sequence number that is used to ensure the packets are received in the correct order. The packets are not numbered, but rather the octets the packets contain are.
Page 207 D-Link DES-3326S Layer 3 Switch The flags and fragment offset are used to keep track of packets that must be divided among several smaller packets to cross networks for which they are too large. The Time-to-Live (TTL) is the number of gateways the packet is allowed to cross between the source and destination. This number is decremented by one when the packet crosses a gateway and when the TTL reaches zero, the packet is dropped.
Page 208 D-Link DES-3326S Layer 3 Switch TCP and UDP Well-Known Ports Application protocols run ‘on top of’ TCP/IP. When an application wants to send data or a message, it gives the data to TCP. Because TCP and IP take care of the networking details, the application can look at the network connection as a simple data stream.
Page 209: The Domain Name System
D-Link DES-3326S Layer 3 Switch The UDP header is shorter than a TCP header. UDP also uses a checksum to verify that data is received uncorrupted. The Internet Control Message Protocol (ICMP) is also a simplified protocol used for error messages and messages used by TCP/IP.
Page 210: Dhcp Servers
D-Link DES-3326S Layer 3 Switch DHCP Servers The Dynamic Host Configuration Protocol (DHCP) is used to dynamically assign a TCP/IP network configuration to network devices and computers on the network. It also ensures that IP address conflicts do not occur.
Page 211: Ip Routing, Multicasting, Multicast Routing And Routing Protocols
D-Link DES-3326S Layer 3 Switch Appendix C IP Routing, Multicasting, Multicast Routing and Routing Protocols IP handles the task of determining how packets will get from their source to their destination. This process is referred to as routing. For IP to work, the local system must be attached to a network. It is safe to assume that any system on this network can send packets to any other system, but when packets must cross other networks to reach a destination on a remote network, these packets must be handled by gateways (also called routers).
Page 212: Arp
D-Link DES-3326S Layer 3 Switch The Address Resolution Protocol (ARP) determines the MAC address and IP address correspondence for a network device. A local computer will maintain an ARP cache which is a table of MAC addresses and the corresponding IP addresses.
Page 213: Multicasting
D-Link DES-3326S Layer 3 Switch Multicasting Multicasting is a group of protocols and tools that enable a single source point to send packets to groups of multiple destination points with persistent connections that last for some amount of time. The main advantage to multicasting is a decrease in the network load compared to broadcasting.
Page 214: Internet Group Management Protocol (Igmp)
D-Link DES-3326S Layer 3 Switch Internet Group Management Protocol (IGMP) End users that want to receive multicast packets must be able to inform nearby routers that they want to become a multicast group member of the group these packets are being sent to.
Page 215: Multicast Routing Algorithms
D-Link DES-3326S Layer 3 Switch Multicast Routing Algorithms An algorithm is not a program. An algorithm is a statement of how a problem can be solved. A program is written to implement an algorithm. Multicast packets are delivered by constructing multicast trees where the multicast router is the trunk, the branches are the various subnetworks that may be present, and the leaves are end recipients of the multicast packets.
Page 216: Multicast Routing Protocols
D-Link DES-3326S Layer 3 Switch if the packet was received on the shortest path back from the router to the source. If the packet was received on the shortest path back to the source, the packet is forwarded on all links except the link on which the packet was received. If the packet was not received on the shortest link back to the source, the packet is dropped.
Page 217: Routing Protocols
D-Link DES-3326S Layer 3 Switch two multicast routers on a network have the same distance back to a multicast source, the router with the lowest IP address is elected. DVMRP also supports tunnel interfaces, where two multicast routers are connected through a router that cannot process multicast packets.
Page 218 D-Link DES-3326S Layer 3 Switch The COMMAND field specifies an operation according the following table: RIP Command Codes Command Meaning Request for partial or full routing information Response containing network- distance pairs from sender’s routing table Turn on trace mode (obsolete) Turn off trace mode (obsolete) Reserved for Sun Microsystem’s...
Page 219 D-Link DES-3326S Layer 3 Switch Routers running RIP version 1 must send different update messages for each IP interface to which it is connected. Interfaces that use the same subnet mask as the router’s network can contain subnetted routes, other interfaces cannot. The router will then advertise only a single route to the network.
