Troubleshooting IPX Layer 3 Routing
Step 3 From the Catalyst 8540-1, use the show ipx servers command to verify the connection to the server in
Novell network 8511, in the example network shown in Figure 11-21.
C8540CSR-1# show ipx servers
Codes: S - Static, P - Periodic, E - EIGRP, N - NLSP, H - Holddown, + = detail
1 Total IPX Servers
Table ordering is based on routing and server info
Type Name Net Address Port Route Hops Itf
P 4 S_8510 8511.0000.0000.0001:0451 5/03 3 Gi11/0/1
Step 4 Confirm that the network (Net) number 8511 appears in the Periodic (indicated with a “P”) row of the
connection list.
Note SAP entries reside in route processor Memory, not on the CAM tables.
Checking the IPX CEF Adjacencies
Follow these steps to check the IPX CEF adjacencies in the IPX Layer 3 connection shown in
Figure 11-22.
Figure 11-22 Checking the IPX CEF Adjacency
Step 1 Use the show ipx ipx-prefix command with the destination network number (8512), netmask, and
interface parameters to display the status of the CAM table on the egress interface.

IPX Prefix Entries in CAM, Interface GigabitEthernet11/0/1
-----------------------------------------------------------------
Codes: C - Connected network, R - Remote network
V - valid entry, N - Network entry
L - load balancing enabled, D - default network
E - EIGRP enabled, I - Internal network
B - BVI network, M - My Mac Address
VC - VCI
GigabitEthernet11/0/1 net 8512 cptr 101D nhop1 101B nhop2 0 encap1 8 encap2 0 flags 9
Step 2 Confirm the following:
• net (network number) appears correctly.
• nhop (next hop) number is correct.
