RADIUS Authentication Features in Alteon OS

Alteon OS supports the following RADIUS authentication features:

„Supports RADIUS client on the switch, based on the protocol definitions in RFC 2138 and RFC 2866.

„Allows RADIUS secret password up to 32 bytes and less than 16 octets.

„Supports secondary authentication server so that when the primary authentication server is unreachable, the switch can send client authentication requests to the secondary authen- tication server. Use the /cfg/sys/radius/cur command to show the currently active RADIUS authentication server.

„Supports user-configurable RADIUS server retry and time-out values:

†Time-out value = 1-10 seconds

†Retries = 1-3

The switch will time out if it does not receive a response from the RADIUS server in 1-3 retries. The switch will also automatically retry connecting to the RADIUS server before it declares the server down.

„Supports user-configurable RADIUS application port.

The default is 1645/UDP-based on RFC 2138. Port 1812 is also supported.

„Allows network administrator to define privileges for one or more specific users to access the switch at the RADIUS user database.

„SecurID is supported if the RADIUS server can do an ACE/Server client proxy. The pass- word is the PIN number, plus the token code of the SecurID card.
