ExtremeWare provides two methods to authenticate users who login to the switch:
• Radius client
• TACACS+
RADIUS C
LIENT
Remote Authentication Dial In User Service (RADIUS, RFC 2138) is a mechanism for
authenticating and centrally administrating access to network nodes. The ExtremeWare
RADIUS client implementation allows authentication for Telnet, Vista, or console access
to the switch.
You cannot configure RADUIS and TACACS+ at the same time.
You can define a primary and secondary RADIUS server for the switch to contact.
When a user attempts to login using Telnet, http, or the console, the request is relayed
to the primary RADIUS server, and then to the secondary RADIUS server, if the
primary does not respond. If the RADIUS client is enabled, but access to the RADIUS
primary and secondary server fails, the switch uses its local database for authentication.
