Troubleshooting IPX SAP
Symptom 1
Unable to add a static service information item to SIT
Solution
Use
display ipx service-table inactive
to see whether the item is inactive. If so, it indicates that no active
route to the destination server exists.
Use
display ipx service-table
to see whether the service information items reach the upper limit. IPX
supports up to 10240 service information items, 2048 service types and 5120 static service items.
Symptom 2
No active service information item in SIT.
Solution
Use
display ipx service-table inactive
to check whether the service information item is inactive. If so, it
indicates that no active route to the destination server exists.
Use
display ipx interface
to verify that the interface is UP and SAP is enabled.
Use
display ipx routing-table
to verify that the active route to the server has a hop number less than 16.
Another possible reason is that no sufficient memory is available to add the service information item to
the SIT. Remove some static service information items.
Symptom 3
No new dynamic service information items in SIT.
Solution
Use
debugging ipx packet
and
debugging ipx sap packet verbose
to check whether relevant packets
are received. If no packet is received, problems in lower layer network connection may exist.
If IPX is disabled, use
ipx enable
in system view to enable IPX.
Use
display ipx interface
to make sure that IPX is configured on relevant interfaces.
If SAP is disabled, use
undo ipx sap disable
to enable SAP.
Check whether the number of SAP service information items reaches the upper limit. The IPX
implementation supports up to 10240 service information items and 2048 service types.
The MTU of SAP should be less that of the physical layer.
Symptom 4
No updates are received on an interface.
Solution
Use
debugging ipx packet
and
debugging ipx sap packet verbose
to check packet contents. All
incoming and outgoing packets are displayed in debugging information. If no related packets are
displayed, problems in lower layer network connection may exist.
Use
display ipx interface
to make sure SAP is enabled on the interface.
Make sure the active route to the server has a hop number less than 16.
Use
display current-configuration
to check whether the updating interval is too long.
