Hi,

I am running following configuration on 7206 with IOS - 12.4(15)T10

interface ATM2/0.10856 point-to-point
  mtu 1500
 no ip redirects
 no ip proxy-arp
 pvc 1/856
  vbr-rt 2048 2048 1
  dbs enable
  encapsulation aal5snap
  max-reserved-bandwidth 100
  protocol pppoe group ft-pppoeoa
 !
end

bba-group pppoe pppoeoa
 virtual-template 661
 sessions per-mac limit 300

interface Virtual-Template661
 no ip address
 ppp authentication chap
end

When I want to see the packets in policy, I can not see even a single
packet in any queue...

Router1#sh policy-map interface ATM2/0.10856
 ATM2/0.10856: VC 1/856 -
