4500 Sup6E Auto QoS Configuration on PortChannel

Hi guys,

I ran into the following issue the other days.

I configured Auto QoS on some access ports on two 4506-E (Sup 6E-L) and I wanted to apply the same generated config on the port channel/port channel members but it didn't work.

Ex:

int gig1/3

service-policy input AutoQos-VoIP-Input-Cos-Policy

% A service-policy with non-queuing actions should be attached to the port-channel associated with this physical port.

service-policy output AutoQos-VoIP-Output-Policy

% A service-policy with non-queuing actions should be attached to the port-channel associated with this physical port.

...then on the portchannel:

int po2

service-policy input AutoQos-VoIP-Input-Cos-Policy -> OK

service-policy output AutoQos-VoIP-Output-Policy

% A service-policy with queuing actions can be attached in output direction only on physical ports. !!!!

After testing a bit, I found out that the "police" and the "priority queue" aren't supported on the memebers/port channel.

I then split the output policy from the Auto QoS config into two policies, one for the port channel (police) and one for the port channel members (priority)..but then the port member was put into suspended state.

Ex:

policy-map PORTCHANNEL-POLICE

class AutoQos-VoIP-Bearer-QosGroup

    police cir 100000000

policy-map MEMBER-PRIORITY

class AutoQos-VoIP-Bearer-QosGroup

    priority

class AutoQos-VoIP-Control-QosGroup26

    bandwidth remaining percent 5

class AutoQos-VoIP-Control-QosGroup24

  bandwidth remaining percent 5

class class-default

    dbl

int gig1/3

service-policy output MEMBER-PRIORITY

int po2

service-policy output PORTCHANNEL-POLICE

service-policy input AutoQos-VoIP-Input-Cos-Policy

The 4506s are running 12.2(53)SG4, IPBASEK9.

Do you have any ideas?

Thanks.
