86 CHAPTER 4: NETWORK PROTOCOL OPERATION
■ The switch receives the GNS packets with the debugging ipx packet sap
command.
■ SAP is enabled on the VLAN interface where the GNS requests are received.
■ The VLAN interface is enabled to respond to GNS requests with the display ipx
interface command. If GNS reply is disabled, execute the undo ipx sap
gns-disable-reply command to enable it.
■ The requested service information is available in the service information table
with the display ipx service table command.
■ The service information is learnt from the interface where the request is
received.
7 SAP does not respond to a GNS request with the server information picked out
through round robin polling.
Verify that:
■ The round robin polling is enabled with the display current-configuration
command.
■ Multiple equivalent service entries are available for the service request. The
service entries are considered equivalent only when they have the same RIP
ticks , RIP hop count, SAP hop count and SAP preference.
Troubleshooting IPX Routing Management
1 The current switch receives the routing information from a neighbor device, but
the route cannot be found on the current switch using the display ipx
routing-table verbose command.
Do the following:
■ Use the display current-configuration command to view the maximum dynamic
route limit for each destination network number; it can be the one configured
using the ipx route max-reserve-path command. The default setting is 4.
■ Use the display ipx routing-table verbose command to check that the
number of the existing dynamic routes to the destination network is under the
limit.
■ If the number of dynamic route entries with the destination network number is
beyond the limit, use the ipx route max-reserve-path command to set a
higher limit to accommodate new dynamic route information.
