[c-nsp] Cisco 7206 and Adtran SM2 blade ADSL

[Denny Reiter]

Anybody here ever terminated ADSL from an Adtran TA3000 using an SM2 
blade on a Cisco 7206 and used DHCP?  I can get DHCP to work using pass 
through, but then I get no circuit id information as far as what port 
the customer is on, etc.  If I enable DCHP authentication on the SM2, I 
get nothing.  Adtran insists it should "just work" and points the finger 
at the Cisco, but doesn't have any ideas as to why it would be blocked.  
I'm messing around with ip dhcp relay options but nothing so far has 
been successful.

Thanks,
