QOS by VLAN

[North323]

has anyone ever done QOS or traffic shapping by VLAN? Do you know what Cisco Switches are able to do this? or any other product for that matter.

The 3560's and 3750's running 12.2(40)SE or higher can apply a service-policy to an SVI. The 4500's running 12.2(40)SG can also. I'm sure others can. Is this what you are after??

you should be able to just add a tag on the vlan interface which will take any traffic seen and tag it with the qos your after. however if a user plugged there dirty old laptop into that vlan there get qos access - no ideal.

I've attached the configuration guides for the 3560s as it relates for QoS. Yes you can indeed supply QoS per vlan but the type of QoS you do and how it is processed, it can be vastly different per model:

I think you'll find you can do much of what you can do with a regular router excluding any outbound queueing performing MQC based configurations. This is definitely different and the options (not to mention commands) are extremely limited.

Anyways, have fun with this and let us know if you have any questions. We got answers!!!
