Cisco 4500 Auto-QOS on Ether-Channel

[rick505d3]

Hi,

Cisco's documentation suggests that auto-qos feature is not supported on ether-channel interfaces. Enabling auto-qos on non-etherchannel interfaces generated all the global qos related configuration and applied service-policy to the interfaces. However, when I try to manually apply the generated service-policy to member-interfaces in an etherchannel, it fails with the following error message.

(config-if)# service-policy input AutoQos-4.0-Input-Policy
class-map match any is not supported for this interface
(config-if)# service-policy output AutoQos-4.0-Output-Policy
% A service-policy with more than one  type of marking field based filters in the  class-map is not allowed on the channel member ports.

There does not seem to a command available as "qos trust cos" or "qos trust dscp":

(config-if)#qos trust ?
  device  trusted device class
  extend  Extend trust through a connected device

The platform is Cisco 4507R+E with Sup-7L-E in VSS mode running 3.4.0 SG (15.1-2 SG). I just need to trust cos/dscp marking on certain etherchannel trunk / access links and prioritise marked traffic (voice/video) on them. Enabling auto-qos on normal interfaces (non-etherchannel) generated the following config.

Yea, you can't apply to the individual interfaces...  I'm used to not being able to apply to the port-channel itself....  Not sure what in the world is going on....
