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.
RFC 1634, Novell IPX Over Various WAN Media (IPXWAN) Hardware compatibility with IPX IPX is not available on the following routers: • MSR 2600. • MSR 30-11. • MSR 30-11E. • MSR 30-11F. • MSR3600-51F. Configuring basic IPX Follow these guidelines when you configure basic IPX:...
• The node address specified with the ipx enable [ node node ] command is the global node address, used by all interfaces but the Ethernet interfaces on the router. If no node address is specified, the router specifies the MAC of the first Ethernet interface as the global node address. If no Ethernet interfaces are available, the router generates the global node address randomly according to the system clock.
Configuring IPX route number limitation In IPX, the maximum number of static and dynamic routes to the same destination address permitted in the routing table can be configured. The number of equivalent routes for load balancing can also be configured. The two configurations have no direct relation, so changing one of the configurations will not affect the other.

Configuring IPX SAP With IPX enabled on an interface, the system will automatically use SAP to maintain and advertise dynamic service information.

Configuring a response mode for IPX SAP GNS request GNS is a SAP message, broadcast by a SAP-enabled NetWare client.

• Enable IPX packet debugging using the debugging ipx packet command. According to the detailed information displayed about IPX packets received, transmitted, forwarded, and discarded, you can locate the error. Packets are discarded If IPX packet debugging information displays that a packet is discarded, and the information displayed is Packet size is greater than interface MTU!, it indicates that the output packet size is greater than the maximum packet size that the interface can transmit.

• Use the display ipx service-table command to check whether the requested service information is available in the SIT table. If not, SAP will not respond. • If the requested service information is available, check whether the service information is learned from the interface that received the GNS requests.
