snap
—
For Ethernet interfaces:
Use Novell Ethernet
Snap encapsulation. This encapsulation consists of a
standard 802.3 MAC header followed by an 802.2 SNAP
LLC header.
For Token Ring and FDDI interfaces:
This
encapsulation consists of a standard 802.5 or FDDI
MAC header followed by an 802.2 SNAP LLC header.

—(Optional) Indicates an additional network
configured after the first (primary) network.

RIP timer
mismatch
You can change RIP timer values changed on servers running
NetWare 4.x or later. Mismatches between routers and servers
can cause connectivity problems.
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.
2.
The timer values configured on servers and routers should be
the same across the whole 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.
Router not
propagating RIP
updates
1.
Use the
debug ipx routing
activity privileged exec
command on the router. Look for routing updates sent by the
router out each interface.
2.
If you do not see RIP updates being sent out the interfaces,
try disabling RIP routing using the no
ipx routing
global
configuration command and then re-enabling it using the
ipx
routing
command.
Use the
show running-config
command to verify that the rest of
the IPX configuration is still correct.
If disabling and re-enabling IPX does not work, try
restarting the router.
