Explanation:
TACACS+ utilizes TCP port 49. It consists of three separate protocols, which can be implemented
on separate servers.[1]
TACACS+ offers multiprotocol support, such as IP and AppleTalk. Normal operation fully encrypts
the body of the packet for more secure communications. It is a Cisco proprietary enhancement to
the original TACACS protocol.http://en.wikipedia.org/wiki/TACACS%2B
