I'm not too sure on the "class voice-control" bandwidth? what does that statement exactly handle?

!
class-map match-any voice-control
match ip dscp af31
match access-group 101
class-map match-any voice
match ip dscp ef
match access-group 100
!
!
policy-map wan-edge
class voice
    priority 6144
class voice-control
    bandwidth 8
class class-default
    fair-queue

That is the amount of bandwidth reserved for this class in the event of any congestion

OK.. got it @ the class voice priority 6144 is for 6M of priority?

Reza Sharifi · ‎12-20-2009

Yes, with no burst size

I think there is an error: 6M is suitable for 192 voice call and you reservs only 8kbps for voice control?!
