Configuring IPX Overview Internetwork packet exchange (IPX) is a network layer protocol of NetWare. Its position in NetWare is similar to IP in TCP/IP. IPX implements such functions as address filling, routing, and packet forwarding. IPX is a connectionless protocol. Though both data and the destination IPX address are included in an IPX packet, IPX does not confirm whether the packet is forwarded successfully.
advertisement to such clients. Because server information is dynamically updated by SAP, clients can always obtain latest server information. SAP defines three types of packets, service query, service response, and periodic updates. The following subsections describe how SAP operates: NetWare client initialization When a NetWare client is initializing, it needs to locate a server. To do so, the client broadcasts a get nearest server (GNS) request.
• A VLAN interface uses its own MAC address as the node address. You need not specify a node address when enabling IPX. • An interface can only have one network number. If the IPX network number of an interface is deleted, its IPX configuration and static routing information are also deleted. To configure basic IPX: Step Command Remark 1. Enter system view. system-view N/A 2. Enable IPX protocol. ipx enable [ node node ] Disabled by default. 3. Enter interface view.
configured. The two configurations have no direct relation, so changing one of the configurations will not affect the other. When the number of dynamic and static routes to the same destination reaches the upper limit, newly found dynamic routes will be discarded instead of being added to the routing table. If the newly configured maximum value is smaller than the previous one, the excessive routes will not be deleted until they get aged out or until they are deleted manually.
Step 5. Command Configure the maximum length of IPX RIP updates. Remark Optional. ipx rip mtu bytes The default is 432 bytes. Configuring IPX SAP With IPX enabled on an interface, the system will automatically use SAP to maintain and advertise dynamic service information. You can also configure the SAP related parameters or service information based on actual network requirements. Configuration prerequisite Configure basic IPX. Enabling IPX SAP Step Command Remark 1. Enter system view.
Step 4. Enter interface view. 5. Configure the maximum length of IPX RIP updates. Command Remark interface interface-type interface-number N/A Optional. ipx sap mtu bytes The default is 480 bytes—seven 64-byte service information items can be included in a SAP update. Configuring a response mode for IPX SAP GNS request GNS is a SAP message, broadcast by a SAP-enabled NetWare client. A NetWare server will respond to the request with a Give Nearest Server message.
The maximum queue length of the same service type items does not limit the amount of static service information but the amount of dynamic service information. If the newly configured queue length is less than the original length, the table items in the service information table will not be deleted; if the amount of service information for the same service type reaches the configured value, new service information items will not be added. To configure IPX service information: Step Command Remark 1.
The type 20 IPX packet is used in NetBIOS. You can either prohibit or permit the forwarding of type 20 broadcast packets based on the actual requirements. To configure IPX triggered updating feature: Step Command Remark 1. Enter system view. system-view N/A 2. Enter interface view. interface interface-type interface-number N/A 3. Enable the IPX triggered update feature. ipx update-change-only Disabled by default. 4. Enable the IPX split horizon feature.
Task Command Remark Display IPX packets statistics. display ipx statistics [ | { begin | exclude | include } regular-expression ] Available in any view. Display the active IPX routing information. display ipx routing-table [ network ] [ | { begin | exclude | include } regular-expression ] Available in any view. Display detailed IPX routing information (both active and inactive).
Figure 1 Network diagram Configuration procedure 1. Configure Router A: # Enable IPX. system-view [RouterA] ipx enable # Enable IPX on the interface Ethernet 1/2, with the network ID being 2. [RouterA] interface ethernet 1/2 [RouterA-Ethernet1/2] ipx network 2 # Set the packet encapsulation format on the Ethernet interface to Ethernet_II. [RouterA-Ethernet1/2] ipx encapsulation ethernet-2 [RouterA-Ethernet1/2] quit # Enable IPX on the interface Ethernet 1/1, with the network ID being 1000.
[RouterB] ipx service 4 server 2.0000-0c91-f61f 451 hop 2 # Configure a Server print service information item. [RouterB] ipx service 26B tree 2.0000-0c91-f61f 5 hop 2 RIP and SAP are automatically enabled when the ipx network command is issued on an IPX interface. Therefore, in this example, no routing protocol is configured. Troubleshooting IPX configuration Troubleshooting IPX forwarding failure IPX cannot go up on a PPP link • Confirm whether network IDs of both ends of the link are the same.
Troubleshooting IPX RIP No routes can be learned from a peer • Enable IPX RIP debugging using the debugging ipx rip packet verbose command. Check whether RIP packets can be received from the peer. If not, problems on the lower layer connection of the two devices might exist. • If a RIP packet with routing information is received from the peer, use the debugging ipx rip event command to see whether the received route is added to the routing table.
• Check whether the number of SAP service information items reaches the upper limit. The IPX implementation supports up to 10240 service information items and 2048 service types. • The MTU of SAP should be less that of the physical layer. No updates are received on an interface • Use the debugging ipx packet and debugging ipx sap packet verbose commands to check packet contents. All incoming and outgoing packets are displayed in debugging information.
• Use the display ipx routing-table command to verify the static route takes effect, and to check whether the next hop address is not specified or not correct on the non PPP interface. Routes received from a neighbor router cannot be found by using the display ipx routing-table verbose command • Use the display current-configuration command to check whether the maximum dynamic route number is configured on a per network ID basis, with the command ipx route max-reserve-path.
