    Can anyone recommend to me if I should use auto-qos settings on my 3550 for a video endpoint
    I am trying to make sure the unit uses the priority queue and is marked cos 5
    THis is what I have come up with for it:

    mls qos map cos-dscp 0 8 16 26 32 46 48 56

    interface FastEthernet0/1
    description Polycom-1
    switchport access vlan 200
    switchport mode access
    switchport nonegotiate
    no ip address
    duplex full
    speed 100
    mls qos cos 5
    mls qos cos override
    mls qos trust cos
    wrr-queue cos-map 1 0 1
    wrr-queue cos-map 2 2 3
    wrr-queue cos-map 3 4
    wrr-queue cos-map 4 5 6 7
    priority-queue out
    spanning-tree portfast
    spanning-tree bpduguard enable
