Troubleshooting Ipx Routing Management - HP A-MSR Series Configuration Manual

Symptom 5
No updates sent out from an interface.
Solution
Use debugging ipx packet and debugging ipx sap packet verbose to check packet contents. If such

update packets are displayed in debugging information, possibly the SAP MTU is larger than the
interface MTU. Hence, the packets are discarded by the lower layer.
Use display ipx interface to check whether the interface is enabled with triggered update. If so, the

interface does not periodically broadcast update packets.
 If no SAP packets are sent out the interface, check whether all service information is learned from the
interface. If so, split horizon may be the reason that no service information is sent out the interface.
Symptom 6
SAP does not respond to GNS requests.
Solution
 Use debugging ipx sap packet to check whether GNS request packets are received.
 Make sure SAP is enabled on the receiving interface.
 Use display ipx interface to check whether the interface is disabled from responding to GNS requests.
If so, use undo ipx sap gns-disable-reply to enable the interface.
Use display ipx service-table to check whether the requested service information is available in the SIT

table. If not, SAP does not respond.
If the requested service information is available, check whether the service information is learned from

the interface that received the GNS requests. In that case, SAP also does not respond to the GNS
requests.
Symptom 7
SAP does not respond to GNS requests in the round-robin mode.
Solution
Use display current-configuration to make sure round-robin is configured.

If round-robin is configured, verify whether multiple equivalent service information items exist for the

service type of the requests. The equivalent service information items must have the same RIP ticks, RIP
hops, SAP hops and SAP preference.

Troubleshooting IPX routing management

Symptom 1
No dynamic routing protocols are configured on the device. The physical status and link layer protocol are
both UP on an interface, but IPX packets cannot be forwarded properly.
Solution
Use display ipx routing-table protocol static to check whether a correct static route is configured.

Use display ipx routing-table to verify the static route takes effect, and to check whether the next hop

address is not specified or not correct on the non PPP interface.
