TACACS+ uses which port?

Explanation:
TacACS+ uses TCP port 49. This protocol runs over TCP to ensure reliable delivery of AAA messages, and port 49 is the standard assigned for it. The other ports map to different services—Telnet uses 23, the RPC portmapper uses 111, and 513 is the login daemon—so they aren’t used by TacACS+.
