COMMAND USAGE
â—† 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.
â—† 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).
