I am troubleshooting a QoS issue for lync traffic.
I have been told that the lync client is having its traffic marked to EF by group policy but the markings are getting stripped somewhere. My starting point is on the access switch Catayst 3560
The configuration on the port is
interface GigabitEthernet0/1
switchport access vlan 10
switchport voice vlan 20
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
mls qos trust cos
auto qos voip trust
I am assuming that in order to trust the DSCP marking from the lync client I need to change mls qos trust cos to mls qos trust dscp
The issue is the port also has a phone in it.
Can anyone provide any more advice on how to trust EF markings for lync (assume this works the same for jabber?) traffic on a port by port basis.
Thanks
Roger
