Troubleshooting RADIUS Server Load Balancing
After configuring the RADIUS Server Load Balancing feature, you can monitor the idle timer, dead timer,
and load balancing server selection or verify the server status by using a manual test command.
SUMMARY STEPS
1. Use the debug aaa test command to determine when an idle timer or dead timer has expired, when test
packets are sent, the status of the server, or to verify the server state.
2.
Use the debug aaa sg-server selection command to determine the server that is selected for load balancing.
3. Use the
test aaa group
command to manually verify the RADIUS load-balanced server status.
DETAILED STEPS
Step 1
Use the debug aaa test command to determine when an idle timer or dead timer has expired, when test packets are sent,
the status of the server, or to verify the server state.
