Per-Port/Per-VLAN QoS - 4510 Sup V

Hello all,

I've been engaged to design and implement QoS for a customer.  The environment is primarily a Campus LAN across multiple buildings in an inner city environment.  The client primarily uses Catalyst 4500 with Supervisor V (classic supervisor) at the access layer.  The wired infrastructure is pretty standard but they have a large wireless environment and all IP phones are wireless (and non Cisco).  As of now, I just have qos trust dscp on the the lan ports connecting to the APs and on the trunked PO interface connected to each 5508 controller.

I'd prefer not to do a blank trust dscp on the interface going to the controller.  I've been looking at the Per-Port/Per-VLAN section for 4500's in the Medianet Campus QoS Design 4.0 guide.  The guide shows the following as an example:


My question is; this interface is configured as a standard end user port with an IP phone and PC coming through the port.  Can you use Per-Port/Per-VLAN configuration on a regular trunked interface with multiple VLANs allowed in the trunk?  I would like to apply one service policy to the wireless voice VLANs and another service policy to the different wireless data VLANs.

Thank you in advance for any input....Scott

I recall (?) vlan-based trust, on a trunk port, will direct trunk vlan traffic to the vlan interface.  Not sure what happens for vlans that don't have a vlan interface on that device.

Per-Port/Per-VLAN QoS - 4510 Sup V

I should have included, in almost all locations, a controller is attached to the 4500 and all WLANs are in H-REAP AND have an SVI on the local 4500.
