When we use" auto qos voip trust" on an interface, the following interface commands are generated.
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
priority-queue out
mls qos trust dscp
I have LACP channel between two 3750 stacks for two 100M site to site links. I heard that auto-qos cannot be appliced to channel so I put those auto-generated command on the physical ports of the LACP channel as shown below.
interface Port-channel1

Do you think that will work? Or should I just use auto-qos (auto qos voip trust) on the physical ports? I do not have switch to test at the movement. Thanks.
