IPX RIP: SAP Updates Not Propagated by Router
Possible Problem
Solution
SAP timer
mismatch has
occurred.
1.
Use the
show running-config
privileged exec command to
view the router configuration. Look for
ipx sap-interval
interface configuration command entries.
Example:
In the following example, SAP updates are sent (and expected)
on serial interface 0 every 5 minutes:
interface serial 0
ipx sap-interval 5
2.
On LAN interfaces, it is recommended that you use the
default SAP interval of 1 minute because the interval on
servers cannot be changed. To restore the default value, use
the
no ipx sap-interval
command. The following is the
syntax for the
ipx sap-interval
command:
ipx sap-interval
minutes
no ipx sap-interval
Syntax description:
minutes
—Interval, in minutes, between SAP updates sent by the
communication server. The default value is 1 minute. If minutes
is 0, periodic updates are never sent.
On serial interfaces, make sure that whatever interval you
configure is the same on both sides of the serial link. Use the
ipx
sap-interval
interface configuration command to change the
SAP interval.
SAP filters have
been
misconfigured.
1.
Use the
show access-lists
privileged exec command on
suspect routers to see whether there are Novell IPX access
lists configured. Use the
show running-config
privileged
exec command to see whether there are SAP filters that use
any of the configured access lists. At the end of this chapter
is a list of Novell SAPs that includes the SAP description
and hex and decimal values.
2.
If SAP filters are configured, disable them by removing
ipx
input-sap-filter
and
ipx output-sap-filter
interface
configuration commands as appropriate (using the
no
version of the command).
3.
Use the
debug ipx sap activity
privileged exec command to
see whether SAP traffic is forwarded normally. The
debug
command output shows the server name, network number,
and MAC address of SAP packets.
