Maximum Retry
Count
At times the NXC may not be able to use the primary RADIUS accounting server. Specify
the number of times the NXC should reattempt to use the primary RADIUS server before
attempting to use the secondary RADIUS server. This also sets how many times the NXC
will attempt to use the secondary RADIUS server.
For example, you set this field to 3. If the NXC does not get a response from the primary
RADIUS server, it tries again up to three times. If there is no response, the NXC tries the
secondary RADIUS server up to three times.
If there is also no response from the secondary RADIUS server, the NXC stops attempting
to authenticate the subscriber. The subscriber will see a message that says the RADIUS
server was not found.

the RADIUS server.
