Defaults
The following defaults are relevant to this feature:
•
No default RADIUS server is defined by default.
•
If you configure a RADIUS server, the accounting feature is disabled by default.
To user a RADIUS server:
1. Open an account for the device on the RADIUS server.
2. Configure that server along with the other parameters in the RADIUS and ADD RADIUS
Server pages.
Note
—If more than one RADIUS server has been configured, the device uses the
configured priorities of the available RADIUS servers to select the RADIUS server to be
used by the device.
To set the RADIUS server parameters:
1. Click
Security > RADIUS
.
2. Enter the default RADIUS parameters if required. If a value is not entered for a specific
server (in the Add RADIUS Server page) the device uses the values in these fields.
•
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 device 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 device and the RADIUS server. This key must match the key
configured on the RADIUS serve. A key string is used to encrypt communications
by using MD5. This overrides the default key string if one has been defined.
3. Click Apply. The RADIUS default settings for the device are updated in the Running
Configuration file.
4. To add a RADIUS server, click Add.
5. Enter the values in the fields for each RADIUS server. To use the default values entered in
the RADIUS page, select Use Default.
•
Add Server—Select whether to specify the RADIUS server by IP address or name.
•
IP Version—Select the version of the IP address of the RADIUS server.
