3. Apply the dot1p trust map and queuing configuration at the system-qos level (global configuration).
OS10# configure terminal
OS10(config)# system qos
OS10(config-sys-qos)# trust-map dot1p TRUST_DOT1P_MAP
OS10(config-sys-qos)# service-policy output type queuing PM_QUEUING
OS10(config-sys-qos)# end

● Verify that the packets are assigned to the respective queues. Packets with dot1p priority 3 must be assigned to queue 3
and packets with dot1p priority 0 must be assigned to queue 0. Bandwidth allocation of 65% to queue 3 ensures that traffic
in queue 3 gets more bandwidth and traffic in other queues get less bandwidth. The drop counter indicates packet drops for
queue 0 whereas there are no drops for queue 3 during traffic congestion.
