<p class="MsoNormal">What about putting your own FreeRadius server in front of the vendor one, and pop together some quick functions to re-map the circuit ID into the username before passing the query on to the vendor FreeRadius? :)<o:p></o:p></p>

back end to look up the static IP address information based on circuit-ID (AVC). Initially we used a Mikrotik router, but with a change in RADIUS server we need the DHCP server to use the circuit-ID as the AAA username, and the Mikrotik only uses the MAC address.
I found that the DHCP server in our Cisco ASR could send the circuit-ID as the AAA username, but it has a “feature” where AAA-based DHCP sessions have a maximum life (defined by Cisco AVPair session-duration, which has to exist and can’t be zero) after which
the DHCP lease is forced to be released and has to be renewed from scratch. This causes a brief outage to the service while they have no IP address, and causes some of our clients to failover to an alternate connection. After a chat with Cisco, I was told
that it was by design and would not be changed or allowed to be overridden.</span><o:p></o:p></p>
