The way it works is that Policy B is matched on and acted upon first.
Within the Policy B, Policy A is acted upon as the router parsed each class.
For instance, if you had
Class http
match protocol http
class everything-else
match not protocol http
policy A
class http
shape average 128000
class everything-else
shape average 256000
class VOICE
match protocol rtp audio
class not-voice
match not protocol rtp audio
policy B
class voice
priority percent 25
class not-voice
bandwidth 384
service-policy out A
This would put the voice in its own class, allowing full priority and also
allow 384 k to all non-voice traffic, but limit http to 128k and allow the
rest of the traffic 256 k. Hope this helps in your understanding.
