Configuring Periodic TACACS+ Server Monitoring on Individual Servers
You can monitor the availability of individual TACACS+ servers. The configuration parameters include the
username and password to use for the server and an idle timer. The idle timer specifies the interval in which
a TACACS+ server receives no requests before the Cisco NX-OS device sends out a test packet. You can
configure this option to test servers periodically, or you can run a one-time only test.
Test parameters that are configured for individual servers take precedence over global test parameters.
Note
To protect network security, we recommend that you use a username that is not the same as an existing
username in the TACACS+ database.
Note
The default idle timer value is 0 minutes. When the idle time interval is 0 minutes, periodic TACACS+ server
monitoring is not performed.
