Thanks a bundle for that, I was about to whack my head against the screen

Yeah, never mind that we are talking to proxy servers upstream which in
turn may talk to other proxy servers (nobody knows) which ultimately talk
to the NAS (BRAS) in question. 
I have seen those quickly recycled Acct-Session-Id's only with one
location it seems, other people with twice the connects never had their
IDs re-used in the same sample period. So my bet is that this particular
NAS will also happily ignore the Class attribute. ^o^

But nevertheless, a very useful configuration snippet that would do well
in a future sample configuration. 

Thanks again for the quick and comprehensive response,
