6. Create a change in the route (for example, shut down a server). Again examine statistics ( ipx
trigrip stats) to verify the change is propagated to other side.
7. If statistics do not reflect change, try the following:
a. Verify triggered RIP/SAP has successfully started for peers. Issue the dr console
command and look for the “starting” message in the log.
b. Generate a triggered RIP/SAP update request to the devices in question. Issue the
following console command for each device:
ipx trigreq
c. Verify that the statistics are incremented properly. Issue the following console commands:
ipx trigrip stats
ipx trigsap stats
d. If routes/services are not propagated on either side, contact Customer Support.
8. Check routing table statistics. Issue the command:
ipx route stats
If the routing table on the CyberSWITCH is full, you will need to adjust your configuration.
Note the following:
The number of entries in the routing table is a configurable entity. This parameter may be
between the values of 20 and 3072, and should be based on system need and system memory
constraints. We recommend this value be at least 10% more than what you predict to be needed
(more than 10% with larger network topologies). To predict need, use the following formula:
1 + (2 x # configured IPX network interfaces) + (# configured static routes) + (# RIP routes)
a. Determine number of needed entries in routing table:
•
Issue the IPX route stats command to determine number of configured static routes and
RIP routes;
• from Manage Mode, issue ipxnetif command to determine number of network
interfaces;
• plug this data into previously-described formula.
b. Run CFGEDIT. From Options, select IPX Routing.
c. Select IPX RIP Table maximum number...
d. Increase the size of the table based upon your calculations.
9. Check the service table statistics. Issue the command:
ipx service stats
10. If the service table on the CyberSWITCH is full, you will need to adjust your configuration.
Note the following:
The number of entries in the service table is a configurable entity. This parameter may be
between the values of 20 and 3072, and should be based on system need and system memory
