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.
