I am trying to configure the WAN side of an 1811 to 1) provide priority to video, 2) limit the bandwidth used by video, and 3) limit the bandwidth used by all traffic. The output of the 1811 is 100 Mbps, but it soon drops to 2.4 Mbps at a wireless modem, so I want to limit at the router so QoS works correctly. Here is my config so far:
class-map match-all VIDEO_DSCP
match ip dscp af41
class-map match-all INTERNET
match not access-group 121
class-map match-all ALL-TRAFFIC
match any
class-map match-all INTERNET_DSCP
match ip dscp default
class-map match-all VIDEO
match access-group 121
!
!
policy-map ingress_mark_policer
class VIDEO
set dscp af41
class INTERNET
set dscp default
policy-map egress_policer
class VIDEO_DSCP
priority 960
policy-map egress_policer_parent
class VIDEO_DSCP
priority 960
police 960000
class ALL-TRAFFIC
shape average 2400000

I am testing with data and video simultaneously. Video limits to 960K, data traffic limits to 2.4M, but when together they run to a combined 3.4 Mbps so my overall traffic shaping is not working. How do I combine the two requirements so data can use the video bandwidth when available but backs down when video is running? Thanks for any help.

Worked like a charm. Thanks for taking time to help me out. JB
