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 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.
Note
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
Nexus 5000 Series switch sends out a test packet.
The default idle timer value is 0 minutes. When the idle time interval is 0 minutes, periodic TACACS+
