Hi all,
I wondering if it is possible to classify QoS based on VLAN's. What I would like to do is have a VLAN for video and a VLAN for internet. If this is possible then can you tell me how.
Thanks,
Stevan

Hi Stevan,
YOu can do the following in a class-map:
class-map match-any dscp_cs1
match ip dscp 8
!
class-map match-all vlan_10
match vlan 10
match class-map dscp_cs1
The following caveats apply:
* You must use the match-all keyword with the class-map global configuration command for the class-map where you match on the VLAN
* Also, this class map must have two match commands in this order: one match vlan vlan-list class-map configuration command and one match class-map class-map-name class-map configuration command. The class map specified in the match class-map class-map-name command must be predefined and cannot contain the match vlan vlan-list and the match class-map class-map-name commands
* Within a policy map, when you use the match vlan vlan-list command, all other class maps must use the match vlan vlan-list command.

Hi,
It depends on the platform that you are using. The Cat3550s do support per-VLAN qos.
Or is this for a router ?

This question was in regards to the Catalyst 3550.
How do you go about configuring it? How do you classify the VLAN in class-map, or is there a different way?
Thanks,
