Managing SteelHeads : Configuring TACACS+ access
  
Configuring TACACS+ access
You set up TACACS+ server authentication in the Administration > Security: TACACS+ page.
TACACS+ is an authentication protocol that allows a remote access server to forward a login password for a user to an authentication server to determine whether access is allowed to a given system.
Enabling this feature is optional.
You can prioritize local, RADIUS, and TACACS+ authentication methods for the system and set the authorization policy and default user for RADIUS and TACACS+ authorization systems in the Administration > Security: General Settings page.
For details about configuring RADIUS and TACACS+ servers to accept login requests from the SteelHead, see the SteelHead Deployment Guide.
