CONFIGURATION
Usage Information
The authentication key must match the key configured on the TACACS+ server. You cannot enter spaces in the key. The show running-configuration output displays both unencrypted and encrypted keys in encrypted format. Configure the global timeout allowed for authentication requests on TACACS+ servers using the tacacs-server timeout command. By default, OS10 times out an authentication attempt on a TACACS+ server after five seconds.

Supported on the MX9116n and MX5108n switches in Full Switch mode starting in release 10.4.0E(R3S). Also supported in SmartFabric mode starting in release 10.5.0.1.

The no version of this command removes a TACACS+ server configuration.
Example 
OS10(config)# tacacs-server host 1.5.6.4 key secret1
Supported Releases
10.4.0E(R2) or later
