Troubleshooting IPX configuration

IPX forwarding failure

Symptom 1
IPX cannot go up on a PPP link.
Solution
Confirm whether network IDs of both ends of the link are the same. Reconfigure them if they are

different.
Confirm whether node IDs of both ends of the link are different. Reconfigure them if they are the same.

Symptom 2
Failed to ping a destination address.
Solution
 Confirm whether the destination address is correct.
Use display ipx interface to check the interface configuration. The network ID and IPX frame

encapsulation format on the directly connected interfaces must be the same.
Use display ipx routing-table to display routing information. Check whether a route to the destination

network is available.
 Enable IPX packet debugging using debugging ipx packet. Use the detailed information displayed
about IPX packets received, transmitted, forwarded, and discarded, to locate the error.
Symptom 3
Packets are discarded.
Solution
If IPX packet debugging information displays that a packet is discarded, and the information displayed

is Packet size is greater than interface MTU!, it indicates that the output packet size is greater than the
maximum packet size that the interface can transmit. Use display interface to check the interface MTU
and use display ipx interface to check the RIP and SAP packet size. If RIP or SAP packet size is greater
than interface MTU, RIP or SAP packet cannot be sent out this interface.
Symptom 4
SAP packets cannot be received.
Solution
 Use display ipx interface to check the receiving interface configuration. If SAP is disabled on this
interface, SAP packets from this interface are discarded.
