QoS configuration in Switch2:

Switch#config

Switch(config)#interface ethernet 1/1

Switch(Config-If-Ethernet1/1)#mls qos trust cos

23.4 QoS Troubleshooting

trust cos can be used with other trust or Policy Map.

trust dscp can be used with other trust or Policy Map. This configuration takes effect

to IPv4 and IPv6 packets.

trust dscp and trust cos may be configured at the same time, the priority is:

DSCP>COS.

If the dynamic VLAN (mac vlan/voice vlan/ip subnet vlan/protocol vlan) is configured,

then the packet COS value equals COS value of the dynamic VLAN.

Policy map can only be bound to ingress direction, egress is not supported yet.

At present, it is not recommended to synchronously use policy map on VLAN and

VLAN’s port.
