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
