RIP and SAP are automatically enabled when the ipx network command is issued on an IPX interface.
Therefore, in this example, no routing protocol is configured.
Troubleshooting IPX configuration
Troubleshooting IPX forwarding failure
IPX cannot go up on a PPP link
• 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.
Failed to ping a destination address
• Confirm whether the destination address is correct.
• Use the display ipx interface command to check the interface configuration. The network ID and IPX
frame encapsulation format on the directly connected interfaces must be the same.
• Use the display ipx routing-table command to display routing information. Check whether a route
to the destination network is available.
• Enable IPX packet debugging using the debugging ipx packet command. According to the detailed
information displayed about IPX packets received, transmitted, forwarded, and discarded, you can
locate the error.
Packets are discarded
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 the display interface command to check the
interface MTU and use the display ipx interface command 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.
SAP packets cannot be received
Use the display ipx interface command to check the receiving interface configuration. If SAP is disabled
on this interface, SAP packets from this interface will be discarded.
IPX type 20 packets cannot be transmitted to any other network segment
• Use the display ipx interface command to check whether the forwarding for IPX type 20 packets is
enabled on the receive/send interfaces. If it is not enabled, IPX type 20 packets cannot be
forwarded.
• Enable IPX packet debugging using the debugging ipx packet command. If the debugging
information displays that the type 20 packet is discarded and the prompt is Transport Control field
of IPX type-20 packet >= 8!, it indicates the IPX type 20 packet can only be forwarded 8 times. If
the upper limit is reached, the IPX type 20 packet will not be forwarded further.
