If a remote authentication server is used, you must specify the

message exchange parameters for the remote authentication protocol.

Both local and remote logon authentication control management access

via the console port, web browser, or Telnet.

RADIUS and TACACS+ logon authentication assign a specific privilege

level for each user name/password pair. The user name, password, and

privilege level must be configured on the authentication server. The

encryption methods used for the authentication process must also be

configured or negotiated between the authentication server and logon

client. This switch can pass authentication messages between the

server and client that have been encrypted using MD5 (Message-Digest

5), TLS (Transport Layer Security), or TTLS (Tunneled Transport Layer

Security).
