The allows you to allocate buffers to queues. If buffers are not allocated, then they are divided equally amongst
all queues. You can use the queue-buffer ratio to divide it in a particular ratio. The buffers are soft buffers
because Dynamic Threshold and Scaling (DTS) is active on all queues by default.
The queue-buffer ratio is supported on wired ports, but the queue-buffer ratio cannot be configured with
a queue-limit.
Note
Examples The following example sets the queue buffers ratio to 10 percent:
Device(config)# policy-map policy_queuebuf01
Device(config-pmap)#
class-map class_queuebuf01
Device(config-cmap)# exit
Device(config)# policy policy_queuebuf01
Device(config-pmap)# class class_queuebuf01
Device(config-pmap-c)# bandwidth percent 80
Device(config-pmap-c)#
queue-buffers ratio 10
Device(config-pmap)# end
