To set the RADIUS server parameters:
STEP 1
STEP 2
• 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.
If the Auto option is selected, the system takes the source IP address from the IP address
