C H A P T E R 16 IPX Routing
299
To increase route stability, you can increase the hold multiplier
(default is 3 for 180 seconds). To modify these parameters use CLI
commands:
configure ipxrip <vlan name> update-interval <time>
hold-multiplier <number>
configure ipxsap <vlan name> update-interval <time>
hold-multiplier <number>
Tagged VLANs and IPX
IPX routing is not supported on tagged VLANs.
IPX and Round-Robin Load Sharing
Due to packet sequencing problems, we do not recommend that IPX
load sharing run with the round-robin load-sharing algorithm.
IPX Performance Testing Using Traffic
Generators
When using traffic generation equipment to test the wire-speed
capability of IPX routing, entries that are allowed to age out with the
ports remaining active cannot be re-learned on that port and will not
be forwarded at wire-speed.
Restarting the port or clearing the FDB will not address this issue.
In a “real-world” IPX environment, clients and servers generally do
not lose communication with the directly attached switch for the
FDB entries to age out.
IPX and Bi-Directional Rate Shaping
Bi-directional rate shaping is not supported for use with IPX traffic.
