Configuring Local/Remote Logon
Authentication
Use the Authentication Settings menu to restrict management access based
on specified user names and passwords. You can manually configure access
rights on the switch, or you can use a remote access authentication server
based on RADIUS or TACACS+ protocols.
Remote Authentication
Dial-in User Service
(RADIUS) and Terminal
Access Controller Access
Control System Plus
(TACACS+) are logon
authentication protocols
that use software running
on a central server to
control access to RADIUS-aware or TACACS- aware devices on the
network. An authentication server contains a database of multiple user
name/password pairs with associated privilege levels for each user that
requires management access to the switch.
RADIUS uses UDP while TACACS+ uses TCP. UDP only offers best
effort delivery, while TCP offers a connection-oriented transport. Also,
note that RADIUS encrypts only the password in the access-request
packet from the client to the server, while TACACS+ encrypts the entire
body of the packet.
