AAA accounting

I configured IAS(RADIUS) on IIS4.0(option pack) & cisco AS2511RJ as NAS.I put radius only as the authentication method & every thing works perfectly except AAA accounting.AAA accounting does not create any logs on the NTserver.(I checked all the basic checks).

Also I am not sure about the entries on the vsa info.(vendor specific attribute).[note that I am using IIS4.0].

Pls help.

Re: AAA accounting

Just turning radius on in the cisco does not turn accounting on, or authorisation on. So you need to make sure that the NAS config is built on "AAA new- model", and has the line "AAA accounting network start-stop radius". Please check the format of that last command, I'm re-calling from memory (eek).
