configure tacacs timeout

configure tacacs timeout seconds


Configures the timeout interval for TACAS+ authentication requests.

Syntax Description

seconds Specifies the number of seconds for authentication requests. Range is 3 to 120 seconds.


The default is 3 seconds.

Usage Guidelines

Use this command to configure the timeout interval for TACACS+ authentication requests.

To detect and recover from a TACACS+ server failure when the timeout has expired, the switch makes one authentication attempt before trying the next designated TACACS+ server or reverting to the local database for authentication. In the event that the switch still has IP connectivity to the TACACS+ server, but a TCP session cannot be established, (such as a failed TACACS+ daemon on the server), failover happens immediately regardless of the configured timeout value.

For example, if the timeout value is set for 3 seconds (the default value), it will take 3 seconds to fail over from the primary TACACS+ server to the secondary TACACS+ server. If both the primary and the secondary servers fail or are unavailable, it takes approximately 6 seconds to revert to the local database for authentication.


The following command configures the timeout interval for TACACS+ authentication to 10 seconds:

configure tacacs timeout 10
