Troubleshooting IPX

1 A destination address cannot be pinged.
2 Packets are discarded.
3 The switch cannot receive SAP packets on a VLAN interface.

Set the IPX packet encapsulation format to Ethernet_SNAP on VLAN interface 2.

Assign the network number 1001 to VLAN interface 1 to enable IPX on the
interface.

Troubleshooting IPX Forwarding
Do the following:
Check that the destination address is correct.
■
Execute the display ipx interface command; check that the network number
■
and IPX frame encapsulation format configured on the interface on the switch
are consistent with those configured on the connected interface.
Execute the display ipx routing-table command; check that the destination
■
network is reachable.
Debug IPX packets with the debugging ipx packet command; check that IPX
■
packets are correctly received, transmitted, forwarded.
If the IPX packet debugging information shows that a packet is discarded because
"Packet size is greater than interface MTU!", do the following:
View the MTU setting on the VLAN interface with the display interface
■
command and the RIP/SAP packet size with the display ipx interface command.
Check that the RIP/SAP packet size is smaller than the MTU setting on the
VLAN interface.
Do the following:
