RIP timer mismatch You can change RIP timer values on servers running NetWare 4.x or later.
Mismatches between routers and servers can cause connectivity problems.
Step 1 Use the show ipx interfaces privileged exec command on the router to
view the state of IPX interfaces. Look for output similar to the following:
C4500#show ipx interface
[...]
Updates each 60 seconds, aging multiples RIP: 3 SAP: 3
[...]
Compare the timer value configured on the router with that configured on
Novell servers.
Step 2 The timer values configured on servers and routers should be the same
across the entire IPX network.
Reconfigure the router or the servers to bring the timer values into
conformance. On the router, use the ipx update-time interface
configuration command to change the RIP timer interval.
For information on changing the timer value configured on Novell servers,
consult your server documentation.
SAP updates are sent
incrementally rather than
periodically
In IPX Enhanced IGRP environments, problems can occur when interfaces are
configured to send incremental (not periodic) SAP updates on segments that have
attached Novell servers. (Incremental SAP updates are sent only when there is a
change in the SAP table.)
Step 1 Use the show running-config privileged exec command to view the router
configuration. Check to see whether there are ipx sap-incremental eigrp
interface configuration command entries enabled on interfaces with
attached Novell clients or servers.
Step 2 If the incremental command is present and the interface in question has
attached Novell clients or servers, you must disable the ipx
sap-incremental eigrp command by using the no version of the command.
This command should be configured on an interface only if all the nodes
attached to that interface are Enhanced IGRP peers.
Novell servers not processing
SAP updates as quickly as
router is generating them
Step 1 Use the show interfaces privileged exec command to check for output
drops.
Step 2 If there are excessive drops, use the show ipx servers exec command on
the router. Compare the output of this command with the output of the
display servers system console command on Novell servers.
Step 3 If the display servers output for a Novell server shows only a partial
listing of the SAP entries shown by the router, the Novell servers might be
unable to process SAP updates as quickly as the router is generating them.
Step 4 Use the ipx output-sap-delay interface configuration command to
configure the delay between packets in a multipacket SAP update. Novell
specifies a delay of 55 ms.
