Hi all,
I have a 2921 series router w 15.1M series IOS. The platform has HWIC-2SHDSL module installed, which is used for point-to-point G.SHDSL connectivity. When I apply a service-policy on atm pvc, after 10 to 20 minutes I lose IP connectivity on ATM interface and tunnel interface also goes to down state. If I remove the service policy on ATM PVC IP connectivty returns back.
Interestingly I use exactly the same config on 2821 platform (w. WIC-1SHDSL installed) and I do not live such an issue on that platform.
I tried to carry the Qos config on to Tunnel interface with shaping enabled and "no qos-preclassify" command issued, but the result is the same.
What may be the cause of that issue?

Hello Selman,
I would suggest to open a Service Request for this issue with TAC.
From the information you have provided you have probably hit a SW defect on the newer router
Hope to help

I have the same issue. I want to know if you solved this problem. I have a case in the TAC, but I have not had the solution.

Hi Samuel,
Yes we solved it
In our case, there was a compatibility issue with HWIC series G.SHDSL cards and ATM DLSAMs in which our ISP uses.
We solved our issue by carrying the the DSLAM ports to another vendors devices, and also to IP DSLAMs.
Hope it helps.
