Tacacs+ primary and Secondary configuration commands

karindia_26 · ‎05-28-2008

Hi

currently we have configured tacacs+ server for controlling access for all routers and switches.we are going to add few more devices into our server in US office before adding this we need to ensure about the redundancy ,high availability of server.Currently we have only one server configured with user and group name sure we will

replicate the same in another server that will be acted like backup when primary Tacacs fails.

Please help me the commands and configuration we need to configure in all devices to contact our new secondary tacacs server when primary fails.

Thanks

On IOS device you just need to add one more tacacs server. First on the list would be primary and if there is no response from primary tacacs , it will fwd request to next listed tacacs server.

This is how you add tacacs on IOS device

Router(config)#tacacs-server host x.x.x.x key cisco

Router(config)#tacacs-server host y.y.y.y key cisco
