Item Description
Max Number of
Retransmits The maximum number of times the RADIUS client on the device will
retransmit a request packet to a configured RADIUS server after a
response is not received. If multiple RADIUS servers are configured,
the max retransmit value will be exhausted on the first server before
the next server is attempted. A retransmit will not occur until the config-
ured timeout value on that server has passed without a response from
the RADIUS server. Therefore, the maximum delay in receiving a
response from the RADIUS server equals the sum of (retransmit -
timeout) for all configured servers. If the RADIUS request was gener-
ated by a user login attempt, all user interfaces will be blocked until the
RADIUS application returns a response.
Timeout Duration The number of seconds the RADIUS client waits for a response from
the RADIUS server. Consideration to maximum delay time should be
given when configuring RADIUS timeout and RADIUS max retransmit
values.
Accounting Mode Specifies whether the RADIUS accounting mode on the device is
enabled or disabled.
NAS-IP Address The network access server (NAS) IP address for the RADIUS server.
To specify an address, click button and enter the IP address of the
NAS in the available field. The address should be unique to the NAS
within the scope of the RADIUS server. The NAS IP address is used
only in Access-Request packets. To reset the NAS IP address to the
default value, click button and confirm the action.
