Problem: My traffic coming inbound appears to be marked but is not marked when egressing.
Setup:
- Ingress from encoder G3/9->> Egress G8/1
- Default DSCP/COS map table (DSCP 24 is COS3)
Cos-dscp map:
cos: 0 1 2 3 4 5 6 7
------------------------------------
dscp: 0 8 16 24 32 40 48 56
1. Any reason COS 3 is not marked outbound on this traffic? I'm determining this by doing a wireshark off of interface g8/1. The traffic appears to be marked on the ingress correctly but does not maintain its mark on the egress. I can confirm this with equipment on other Ethernet links in produciton as well as my test port listed in the config below with wireshark.
FYI: Unfortunately with my cards in the 6509 I cannot port mirror and see outbound multicast (determined through a TAC case). Because the STB does not understand tagged traffic I setup the native vlan for it to function. To see the multicast with tags I temporarily remove the native command and do the wireshark to see the multicast. It still shows a COS setting of 0. I will try to attach a capture of a multicast packet.

2. I've continued to try and mark on the egress but have problems with the configuration. I'm ingressing on g3/9 and egressing on 8/1 for my test.
Egress Attempt 1:
PhatCat(config-if)#service-policy output MARK_OUTBOUND_VIDEO
MQC features are not supported in output direction for this interface
Egress Attempt 2:
PhatCat(config)#int vlan 781PhatCat(config-if)#service-policy output MARK_OUTBOUND_VIDEO
set cos cannot be configured on output direction for this interface
Configuration failed!
%'set cos cos-inner' for 'class OUT_VIDEO' on Vlan781 is not supported
('set cos cos-inner' is only supported on a class with 'match vlan' or on 'class class-default')
