Example: Monitoring Idle Timer
The following example shows idle timer and related server state for load balancing enabled for a named
RADIUS server group. The current configuration of the RADIUS command output and debug command
output are also displayed.
The following sample output shows the relevant RADIUS configuration:
Device# show running-config | include radius
aaa group server radius server-group1
radius-server host 192.0.2.238 auth-port 2095 acct-port 2096 test username junk1 idle-time
1 key cisco
radius-server host 192.0.2.238 auth-port 2015 acct-port 2016 test username junk1 idle-time
1 key cisco
radius-server load-balance method least-outstanding batch-size 5
The lines in the current configuration of the preceding RADIUS command output are defined as follows:
• The aaa group server radius command shows the configuration of a server group.
• The radius-server host command defines the IP address of the RADIUS server host with authorization
and accounting ports specified and the authentication and encryption key identified.
• The radius-server load-balance command enables load balancing for the RADIUS server with the
batch size specified.
The show debug sample output below shows test requests being sent to servers. The response to the test
request sent to the server is received, the server is removed from quarantine as appropriate, the server is marked
alive, and then the idle timer is reset.
