Users Guide

Each egress queue of an interface can be scheduled as per Weighted Decit Round Robin (WDRR) or by strict-priority (SP), which are
mutually exclusive. If the bandwidth percent command is present, you cannot congure 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 congure 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 congure a policy-map name in CONFIGURATION mode.
policy-map type queuing policy-map-name
5 Congure 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.

Service-policy rate-shaping
Rate-shaping buers trac exceeding the specied rate until the buer is exhausted. Trac transmit rates that exceed the congured
rate-shape value causes the system to buer the exceeding trac. This will use all of the buers assigned to that interface or queue
combination.
1 Enter the policy-map type as queuing and congure 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 specic queue, match the corresponding qos-group in the class-map. If you do not congure
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}
