auto qos trunks and port-channels

[Steven Williams]

So according to the documentation auto qos is not available on port-channels or members of port-channels. So when using auto-qos at the access layer what do you do to trunks that are part of a port-channel?

It also appears that members of port-channels on my 2960 will not take auto-qos command but members of port-channels on my Cat9300 will take the command.

It maybe because the 9300 has auto QOS enabled already. So, on the 2960, try to run auto qos on a physical port that is not being used for anything. That should generate the policies. Once that is completed, try and apply the qos command to the physical ports that are member of a Portchannel and see if it takes it.

Doesnt seem to change. I can use "mls qos trust dscp" but nothing to do with auto qos

Hello
Possibly apply it to the physical ports BEFORE they are put into a PC , what SDM template are you using?

[Reza Sharifi]

Did you try generating the policy by applying the auto qos policy on an unused port first?

[Steven Williams]

I guess on 2960 series you have to pull the interfaces out of the port-channel then add the qos.
