External Query to Cisco Access Registrar

[pavlosd]

Hi all.

We are currently implementing a video solution.

There are some rewuirements from Video server's site that it should be able to Query the Radius server for a Username to IP address mapping (provided that the IP address assignment is done dynamically). For example, Video server asks Radius, Who is user 192.168.99.2? I am not quite sure if such an interface exists on CAR or how it could be done. Any ideas?

Regards.

Hi all,

I have some additional info that might help. To be more specific. The requirement has to do with 3GPP standards. A AAA client has a user and a password.

During an Access-Request packet, the client sends a packet in the format Access-Request[User-Name, User-Pass, Framed-IP-Address], where Username and Password are the Video servers Credentials and Framed-IP-Address is the IP address of an active user.

The Radius Responese back with an Accept-Accept[Calling-Station-Id].

Any ideas?

This functionality may be provided in the Identity Caching feature:
