Page 27: Before You Connect To The Network
D-Link DES-3326SR Layer 3 Switch Before You Connect to the Network Before you connect to the network, you must install the Switch on a flat surface or in a rack, set up a terminal emulation program, plug in the power cord, and then set up a password and IP address.
Page 28: Password Protection
Password Protection The DES-3326SR does not have a default user name and password. One of the first tasks when settings up the Switch is to create user accounts. If you log in using a predefined administrator-level user name you have privileged access to the Switch’s management software.
Page 29: Ip Address Assignment
D-Link DES-3326SR Layer 3 Switch IP Address Assignment Each Switch must be assigned its own IP Address, 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 10.90.90.90.
Page 30: Snmp Settings
The DES-3326SR supports the SNMP versions 1, 2c, and 3. You can specify which version of the SNMP you want to use to monitor and control the Switch. The three versions of SNMP vary in the level of security provided between the management station and the network device.
Page 31: Installing The Switch Without The Rack
D-Link DES-3326SR Layer 3 Switch allowed to view read-only information or receive traps using SNMP v.1 while assigning a higher level of security to another group, granting read/write privileges using SNMP v.3. Using SNMP v.3 individual users or groups of SNMP managers can be allowed to perform or be restricted from performing specific SNMP management functions.

The Web-based Management agent of the Master Switch can configure and manage all of the Switches in a Switch stack −...
Page 34: Notes On Stacking Switches
Auto: This is the default stacking mode setting for the DES-3326SR. In auto stacking mode the Switch is eligible for stacking or it can operate as a standalone device. If a DES-3326SR Switch stack is connected and all units are configured to operate in auto stacking mode, the master-slave relationships is determined automatically.
Page 35: Configuring A Switch Group For Stacking
Configuring a Switch Group for Stacking In order to set up a stack of DES-3326SR 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 36: Notes On Standalone Operation
Notes on Standalone Operation The DES-3326SR 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.
Page 37 D-Link DES-3326SR Layer 3 Switch To Disable Stacking If you prefer to disable stacking for a standalone Switch, use the CLI command config stacking mode disable. Once stacking mode has been disabled on a Switch, do not use the stacking ports (if there are any installed).
Page 38: Connecting Devices To The Switch
STACK NO. The Master Switch in the stack will display STACK NO. 1. The remaining slaves display the STACK NO. 2 to 13 according to the position in the logical stack order. Figure 2 - 11. DES-3326SR Stacking Module Front Panel Connecting Devices to the Switch These connections can be accomplished at any port in either straight-through cable or a crossover cable because the switch supports Auto-MDIX function.
Page 39: Installing A Redundant Power Supply

D-Link DES-3326SR 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 167: Ospf Cost
D-Link DES-3326SR 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-3326SR 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.
Page 170: Ospf Authentication
D-Link DES-3326SR 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-5).
Page 171: Designated Router Election
D-Link DES-3326SR 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.

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 187 D-Link DES-3326SR 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 188: Ospf Interface Configuration
D-Link DES-3326SR 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.

Page 191: Area Aggregation Configuration
D-Link DES-3326SR 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 192: Ospf Host Route Settings
D-Link DES-3326SR 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 193: Route Redistribution Settings
This information is then exchanged among the various routers according to the individual routers current routing protocol. The DES-3326SR can redistribute routing information between the OSPF and RIP routing protocols to all routers on the network that are running OSPF or RIP. Routing information entered into the Static Routing Table on the local DES-3326SRs Switch is also redistributed.
Page 194 D-Link DES-3326SR Layer 3 Switch To edit an existing Route Redistribution entry on the switch, select the entry from the Route Redistribution screen and click on the Edit button: Figure 24- 18.

D-Link DES-3326SR Layer 3 Switch Appendix B Network Addressing and Protocols This appendix provides background information pertaining to Layer 3 IP networking including IP addressing, network protocols and the composition of packet headers. IP Addressing and Subnetting This section gives basic information needed to configure your Layer 3 Switch for IP routing. The information includes how IP addresses are broken down and how subnetting works.
Page 198: Address Classes
D-Link DES-3326SR Layer 3 Switch The dots are included to make the numbers easier to read. Eight binary bits are called a ‘byte’ or an ‘octet’. An octet can represent any decimal value between ‘0’ (00000000) and ‘255’ (11111111). IP addresses, represented in decimal form, are four numbers whose value is between ‘0’ to ‘255’. The...
Page 199: Subnet Masking
D-Link DES-3326SR Layer 3 Switch For example, the IP address 10.42.73.210 is a Class A address, so the Network part of the address (called the Network Address) is the first octet (10.x.x.x). The node part of the address is the last three octets (x.42.73.210).
Page 200 D-Link DES-3326SR Layer 3 Switch Multiplying the number of subnets times the number of nodes gives 12,582,900 possible nodes. Note that this is less than the 16,777,214 possible nodes that an unsubnetted class A network would have. Subnetting reduces the number of possible nodes for a given network, but increases the segmentation of the network.

Page 202: Internet Protocols
D-Link DES-3326SR 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 203 D-Link DES-3326SR 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 204: Packet Headers
D-Link DES-3326SR 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 205 D-Link DES-3326SR Layer 3 Switch TCP must know how large a packet the network can process. To do this, the TCP protocols at each end of a connection state how large a packet they can handle and the smaller of the two is selected.
Page 206 D-Link DES-3326SR 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 207: Udp And Icmp
D-Link DES-3326SR 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 208: The Domain Name System
The Domain Name System (DNS) is used to map names to IP addresses throughout the Internet and has been adapted for use within intranets. For two DNS servers to communicate across different subnets, the DNS Relay of the DES-3326SR must be used. The DNS servers are identified by IP addresses.
Page 209: Dhcp Servers
Address Resolution Protocol (ARP) request that contains its new IP address. For two DHCP servers to communicate across different subnets, the BOOTP/DHCP Relay of the DES-3326SR must be used. The DHCP servers are identified by IP addresses.
Page 210: Ip Routing, Multicasting, Multicast Routing And Routing Protocols
D-Link DES-3326SR 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 211: Arp
D-Link DES-3326SR 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 212: Multicasting
D-Link DES-3326SR 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 213: Internet Group Management Protocol (Igmp)
D-Link DES-3326SR 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 214: Multicast Routing Algorithms
D-Link DES-3326SR Layer 3 Switch The router with the lowest IP address is elected as the querier. The explicit group leave message is added to decrease latency, and routers can ask for membership reports from a particular multicast group ID.
Page 215: Multicast Routing Protocols
D-Link DES-3326SR Layer 3 Switch Reverse Path Broadcasting (RPB) The Reverse Path Broadcasting (RPB) algorithm is an enhancement of the multicast spanning tree algorithm. RPB constructs a spanning tree for each multicast source. When the router receives a multicast packet, it then checks to determine if the packet was received on the shortest path back from the router to the source.
Page 216: Routing Protocols
D-Link DES-3326SR Layer 3 Switch shortest path back to the multicast source, or that have no active multicast group members. A ‘graft’ message is added that allows a previously pruned branch of the multicast delivery tree to be reactivated. This allows for lower latency when a leaf router adds a new member to a multicast membership group.
Page 217: Rip Version 1 Message Format
D-Link DES-3326SR Layer 3 Switch RIP Version 1 Message Format There are two types of RIP messages: routing information messages and information requests. The same format is used by both types. The COMMAND field specifies an operation according the following table:...
Page 218: Rip 1 Route Interpretation
D-Link DES-3326SR Layer 3 Switch The distances, measured in router hops are entered in the Distance to Source Network, and Distance to Destination Network fields. RIP 1 Route Interpretation RIP was designed to be used with classed address schemes, and does not include an explicit subnet mask. An extension to version 1 does allow routers to exchange subnetted addresses, but only if the subnet mask used by the network is the same as the subnet mask used by the address.
