Marking down VC from AF41 on the LAN to AF31 for the WAN

[jayesh.shah]

How do I 'mark-down' VC calls from AF41 (COS 4) on the LAN to AF31 (COS 3) for the WAN provider? (The WAN provider is looking at AF31 and designating that as Video traffic when it connects to their network). Do I do this on the router or on the switches? Are there any sample configs available?

hi

if your switch is already marking this VC calls as COS 4 and sending it to your router then you can define a class map matching all the cos4 marked traffic and set cos 3 under the policy map while remarking.

Place the service policy on the outgoing interface facing your SP side...

just try this out and revert back how it goes...
