Dear all,
i am setup a lab the test the QOS on bridge-domain and configure and sample output as below:
I found the QoS is not work, can anyone help me
class-map match-all IAS_AFCD

Hello Ng,
two notes:
the bridge-domain is a command that allows bridging between Giga subifs
http://www.cisco.com/en/US/docs/ios/lanswitch/command/reference/lsw_b1.html#wp1017027
in your configuration I don't see the second subif in the bridge (at least a second one to bridge)
in addition all examples show they use different values for the enc dot1q and the bridge-domain command
see the following example
Router(config)# vlan 100
Router(config-vlan)# exit
!
Router(config)# interface GigabitEthernet 1/0/1.1
Router(config-subif)# encapsulation dot1q 10
Router(config-subif)# bridge-domain 100 dot1q
Router(config-subif)# exit
!
Router(config)# interface GigabitEthernet 1/0/2.1
Router(config-subif)# encapsulation dot1q 20
Router(config-subif)# bridge-domain 100 dot1q
This could explain why the QoS never matches no traffic is going through the bridge being the bridge single-arm.
Hope to help
Giuseppe
