I have been investigating issues where certain phones traffic is not passing QoS parameters across the LAN. I started walking back through the network and got all the way to the access switch where I did a "show mls qos inter fa XX" and found the following.
trust state: not trusted
trust mode: trust cos
trust enabled flag: dis
COS override: dis
default COS: 0
DSCP Mutation Map: Default DSCP Mutation Map
Trust device: cisco-phone
qos mode: port-based
This port appears in "show cdp nei"
SEP0019E7290456 Fas 3/0/22 46 H P IP Phone 7Port 1
Here is the configuration on the port:
switchport access vlan 2
switchport mode access
switchport voice vlan 12
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
mls qos trust device cisco-phone
mls qos trust cos
auto qos voip cisco-phone
no mdix auto
I have been going through the switch line by line and I have not found anything that would indicate why 90% of the ports on the switch are in a not trusted state, but 10% are.
Here is the output of the "show mls qos" command
QoS is enabled
QoS ip packet dscp rewrite is enabled
Can anyone offer any assistance before I open a TAC case?
