TACACS+ server
TACACS+ is a remote authentication protocol that provides access control for routers, network access servers, and other networked computing devices using one or more centralized servers. TACACS+ allows a client to accept a user name and password and send a query to a TACACS+ authentication server. The server host determines whether to accept or deny the request and sends a response back that allows or denies the user access to the network.
TACACS+ offers fully encrypted packet bodies and supports both IP and AppleTalk protocols. TACACS+ uses TCP port 49, which is seen as more reliable than RADIUS’s UDP protocol.
To configure TACACS+ authentication using the GUI:
- Go to System > Authentication > TACACS and select Add Server.
