Configuring the RADIUS Vendor ID
The vendor-specific attribute (VSA) identifies the device to the RADIUS server using the Vendor ID
(as registered with the Internet Assigned Numbers Authority or IANA). The device's default vendor
ID is 5003 which can be changed, as described in the following procedure. For an example of using
the Vendor ID, see
Setting Up a Third-Party RADIUS Server . The procedure is applicable to both
RADIUS-based user authentication and RADIUS-based accounting.
The Vendor ID must be the same as the Vendor ID set on the third-party RADIUS
server. See the example for setting up a third-party RADIUS server in Setting Up a
Third-Party RADIUS Server .
➢
To configure the RADIUS Vendor ID:
1. Open the Authentication Server page ( Setup menu > Administration tab > Web & CLI folder
> Authentication Server ).
2. Under the RADIUS group, in the 'RADIUS VSA Vendor ID' field, enter the same vendor ID
number as set on the third-party RADIUS server.
3. Click Apply .
RADIUS-based Management User Authentication
You can enhance security for your device by implementing Remote Authentication Dial-In User
Service (RADIUS - RFC 2865) for authenticating multiple management user accounts of the
device’s embedded Web and Telnet (CLI) servers. Thus, RADIUS also prevents unauthorized
access to your device.
When RADIUS authentication is not used, the user's login username and password are locally
authenticated by the device using the Local Users table (see
Configuring Management User
Accounts ). However, you can configure the device to use the Local Users table as a fallback
mechanism if the RADIUS server does not respond.
If you enable RADIUS- based user login authentication, when users with Security
Administrator privilege level log in to the device’s CLI, they are automatically given
access to the CLI privileged mode (“#”). For all other user privilege levels, the user
needs to run the
enable command and then enter the password to access the CLI
privileged mode.
