[cisco-bba] PPPoE and QOS for voice traffic

[Eric Helm]

In a PPPoE environment, can QOS aware Layer 2 devices "see" the TOS or 
DiffServ if it is set in the IP packets? Or will it just see the traffic 
as Layer 2 traffic and be totally blind of anything IP contained within 
the PPPoE encapsulation?
If this cannot be done, what methods are available to prioritize traffic 
in a PPPoE environment. Specifically, we use DSL and Wireless with PPPoE 
for customers.

Thanks,
Eric
