Each egress queue of an interface can be scheduled as per Weighted Deficit Round Robin (WDRR) or by strict-priority (SP), which are mutually exclusive. If the bandwidth percent command is present, you cannot configure the priority command as it is used to assign bandwidth to a queue. In S5148F-ON, bandwidth weight is equally applied to UC and MC. 1 Create a class-map of type queuing and configure a name for the class-map in CONFIGURATION mode. class-map type queuing class-map-name 2 Apply the match criteria for the QoS group in CLASS-MAP mode. qos-group queue-number 3 Return to the CONFIGURATION mode. exit 4 Create a policy-map of type queuing and configure a policy-map name in CONFIGURATION mode. policy-map type queuing policy-map-name 5 Configure a queuing class in POLICY-MAP mode. class class-name 6 Assign a bandwidth percent (1 to 100) to nonpriority queues in POLICY-MAP-CLASS-MAP mode. bandwidth percent value Configure bandwidth allocation OS10(config)# class-map type queuing solar OS10(conf-cmap-queuing)# match qos-group 5 OS10(conf-cmap-queuing)# exit OS10(config)# policy-map lunar OS10(config)# policy-map type queuing lunar OS10(conf-pmap-queuing)# class solar OS10(conf-pmap-c-que)# bandwidth percent 80 View class-map OS10(conf-cmap-queuing)# do show class-map Class-map (queuing): solar (match-any) Match: qos-group 5 View policy-map OS10(conf-pmap-c-que)# do show policy-map Service-policy (queuing) output: solar Class-map (queuing): lunar bandwidth percent 80 Service-policy rate-shaping Rate-shaping buffers traffic exceeding the specified rate until the buffer is exhausted. Traffic transmit rates that exceed the configured rate-shape value causes the system to buffer the exceeding traffic. This will use all of the buffers assigned to that interface or queue combination. 1 Enter the policy-map type as queuing and configure a policy-map name in CONFIGURATION mode. policy-map type queuing policy-map-name 2 Enter a class name to apply to the shape rate in POLICY-MAP-QUEUEING mode-up to 32 characters. class class-name 3 (Optional) If you need rate shaping on a specific queue, match the corresponding qos-group in the class-map. If you do not configure the match qos-group command, rate shaping applies to all queues. match qos-group queue-number 4 Enter a minimum and maximum shape rate value in POLICY-MAP-QUEUEING-CLASS mode. shape {min {kbps | mbps}min-value} {max {kbps | mbps}max-value} Quality of service 449
