5 Create a queuing policy map in CONFIGURATION mode. Enter POLICY-CLASS-MAP mode and configure the percentage of bandwidth allocated to each traffic 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 configure a queue as strict priority, use the priority command. Packets scheduled to a strict priority queue are transmitted before packets in non-priority queues. policy-map type queuing policy-map-name class class-map-name priority 6 Apply the trust maps for dot1p and DSCP values, and the traffic 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 trust-map dscp dscp-map-name qos-map traffic-class queue-map-name 7 Apply the qos trust policy to ingress traffic in SYSTEM-QOS or INTERFACE mode. service-policy input type qos trust-policy-map-name 8 Apply the queuing policy to egress traffic in SYSTEM-QOS or INTERFACE mode. service-policy output type queuing policy-map-name 9 Enable ETS globally in SYSTEM-QOS mode or on an interface/interface range in INTERFACE mode. ets mode on Configure ETS OS10(config)# trust dot1p-map dot1p_map1 OS10(config-trust-dot1pmap)# qos-group 0 dot1p 0-3 OS10(config-trust-dot1pmap)# qos-group 1 dot1p 4-7 OS10(config-trust-dot1pmap)# exit OS10(config)# trust dscp-map dscp_map1 OS10(config-trust-dscpmap)# qos-group 0 dscp 0-31 OS10(config-trust-dscpmap)# qos-group 1 dscp 32-63 OS10(config-trust-dscpmap)# exit OS10(config)# qos-map traffic-class tc-q-map1 OS10(config-qos-tcmap)# queue 0 qos-group 0 OS10(config-qos-tcmap)# queue 1 qos-group 1 OS10(config-qos-tcmap)# exit OS10(config)# system qos OS10(config-sys-qos)# trust-map dot1p default OS10(config)# class-map type queuing c1 OS10(config-cmap-queuing)# match queue 0 OS10(config-cmap-queuing)# exit OS10(config)# class-map type queuing c2 OS10(config-cmap-queuing)# match queue 1 OS10(config-cmap-queuing)# exit OS10(config)# policy-map type queuing p1 OS10(config-pmap-queuing)# class c1 Converged data center services 653
