I would like to apply an outbound QoS policy on a L2 interface of my 4507 switch where my WAN router is connected.
As soon as I assign the policy, all traffic is retag as DSCP 0
Here are my QoS policy:
Policy Map WAN-Output-Policy
Class VoIP-RTP-Class
set dscp ef
Class VoIP-Control-Class
set dscp af31
Class Video-Class
set dscp af31
Class SAP-Class
set dscp af21
Class BestEffort-Class
set dscp default
Here is the config of the interface:
interface FastEthernet6/1
description WAN Router 1
switchport mode access
service-policy output WAN-Output-Policy
speed 100
duplex full
end
The traffic match my different class-map, however it is not tagged as I want
here is the "sh policy-map interface fa6/1"
Service-policy output: WAN-Output-Policy
Class-map: VoIP-RTP-Class (match-any)
2 packets
Match: access-group name VoIP-RTP-Access-List
2 packets
QoS Set
ip dscp ef
Packets marked 0
Class-map: VoIP-Control-Class (match-any)
647 packets
Match: access-group name VoIP-Control-Access-List
647 packets
QoS Set
ip dscp af31
Packets marked 0
Class-map: Video-Class (match-any)
33 packets
Match: access-group name Video-Access-List
33 packets
QoS Set
ip dscp af31
Packets marked 0
...
Any idea why?
Thanks in advance

Is QoS and IP header DSCP rewrite enabled globally?
Do "show qos".

Why dont you post the entire switch config? You didnt post the class maps, just the policy map...

Ok, thanks all, I finally found the issue. My policy-maps did match the traffic as I expected (confusion between the source and destination ports). Everything is ok now.
Thank you!
