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:
Click Security > RADIUS Client.
Enter the RADIUS Accounting option. The following options are available:
•
Port Based Access Control (802.1X, MAC Based, Web Authentication)—Specifies
that the RADIUS server is used for 802.1x port accounting.
•
Management Access—Specifies that the RADIUS server is used for user login
accounting.
•
Both Port Based Access Control and Management Access—Specifies that the
RADIUS server is used for both user login accounting and 802.1x port accounting.
•
None—Specifies that the RADIUS server is not used for accounting.
Enter the default RADIUS parameters if required. 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 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 server. A key string is used to encrypt communications by using MD5.
The key can be entered in Encrypted or Plaintext form. If you do not have an encrypted
key string (from another device), enter the key string in plaintext mode and click Apply.
The encrypted key string is generated and displayed.
This overrides the default key string if one has been defined.
•
Source IPv4 Interface—Select the device IPv4 source interface to be used in messages
for communication with the RADIUS server.
•
Source IPv6 Interface—Select the device IPv6 source interface to be used in messages
for communication with the RADIUS server.
