Configuring RADIUS Parameters
Remote Authorization Dial-In User Service (RADIUS) servers provide a centralized
802.1X or MAC-based network access control. The switch is a RADIUS client that
can use a RADIUS server to provide centralized security.
For the RADIUS server to grant access to the web-based switch configuration
utility, the RADIUS server must return cisco-avpair = shell:priv-lvl=15.
To set the RADIUS server parameters:
STEP 1 Click Security > RADIUS. The RADIUS page displays.
STEP 2 Enter the default RADIUS parameters. Values entered in the Default Parameters
are applied to all servers. If a value is not entered for a specific server (in the Add
RADIUS Server page) the switch uses the values in these fields.
IP Version—Displays the supported IP version: IPv6 and/or IPv4 subnet.
Retries—Enter the number of transmitted requests that are sent to the
RADIUS server before a failure is considered to have occurred.
Timeout for Reply—Enter the number of seconds that the switch waits for
an answer from the RADIUS server before retrying the query, or switching to
the next server.
Dead Time—Enter the number of minutes that elapse before a non-
responsive RADIUS server is bypassed for service requests. If the value is 0,
the server is not bypassed.
Key String—Enter the default key string used for authenticating and
encrypting between the switch and the RADIUS server. This key must match
the key configured on the RADIUS server. A key string is used to encrypt
communications by using MD5. A key configured for an individual RADIUS
server has precedence over the default key that is used if there is no key
provided for an individual server.
STEP 3 Click Apply. The RADIUS settings for the switch are updated in the Running
Configuration file.
