This initial release of support for the second CPU on the 7301 only
supports PPPoEoE and PPPoEoVLAN forwarding into an L2TP tunnel. PTA of
PPPoEoX sessions is not supported, which means there is no support for
ACL's, QoS, etc which are generally features seen on PTA LAC's and
LNS's. I wouldn't hold my breath for shaping/LLQ support. Currently we
are only looking at supporting classification, policing and marking in
our broadband architecture.
