5 Create a queuing policy map in CONFIGURATION mode. Enter POLICY-CLASS-MAP mode and congure the percentage of
bandwidth allocated to each trac class-queue mapping. The sum of all DWRR-allocated bandwidth across ETS queues must be
100%, not including the strict priority queue. Otherwise, QoS automatically adjusts bandwidth percentages so that ETS queues always
receive 100% bandwidth. The remaining non-ETS queues receive 1% bandwidth each.
policy—map type queuing policy—map-name
class class—map-name
bandwidth percent {1-100}
(Optional) To congure a queue as strict priority, use the priority command. Packets scheduled to a strict priority queue are
transmitted before packets in non-priority queues.

6 Apply the trust maps for dot1p and DSCP values, and the trac class-queue mapping globally on the switch in SYSTEM-QOS mode
or on an interface or interface range in INTERFACE mode.
system qos
trust-map dot1p dot1p-map-name
trust-map dscp dscp-map-name
qos-map traffic-class queue-map-name
Or
interface {ethernet node/slot/port[:subport] | range ethernet node/slot/port[:subport]-node/
slot/port[:subport]}
trust-map dot1p dot1p-map-name

7 Apply the qos trust policy to ingress trac in SYSTEM-QOS or INTERFACE mode.

8 Apply the queuing policy to egress trac in SYSTEM-QOS or INTERFACE mode.
