Configuring Periodic TACACS+ Server Monitoring
You can monitor the availability of TACACS+ servers. These 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 Nexus 5000 Series switch sends out a test packet.You can configure
this option to test servers periodically, or you can run a one-time only test.
To protect network security, we recommend that you use a user name that is not the same as an existing

username in the TACACS+ database.
The test idle timer specifies the interval in which a TACACS+ server receives no requests before the Cisco
Nexus 5000 Series switch sends out a test packet.
