Troubleshooting IPX forwarding
Symptom 1: A destination address cannot be pinged.
Solutions:
Check whether the destination address is correct.
■
Use the display ipx interface command to check whether the network number
■
and IPX frame encapsulation format configured on the interface of the switch
are consistent with those configured on the connected interface.
Use the display ipx routing-table command to check whether the destination
■
network is reachable.
Use the debugging ipx packet command to enable debugging for IPX packets.
■
Check whether IPX packets are correctly received, transmitted, forwarded, and
dropped.
Symptom 2: Packets are dropped.
Solutions:
If the IPX packet debugging information shows that a packet is dropped
■
because "Packet size is greater than interface MTU!", perform the following
