Table8-12 Novell IPX: Intermittent Connectivity (continued)
Possible Problem
Solution
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.)
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.
1.
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.
2.
Novell servers not
processing SAP updates as
quickly as the router is
generating them.
1.
Use the
show interfaces
privileged exec
command to check for output drops.
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.
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
incapable of processing SAP updates as quickly as
the router is generating them.
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.
