OS10 Enterprise Edition User Guide Release 10.4.0E(R3)


Configure egress buffer

Default settings

All port queues are allocated with reserved buffers and when the reserved buffers are consumed, each queue starts using the shared buffer from the default pool.

The reserved buffer per queue is 1664 bytes for the speed of 10G, 25G, 40G, 50G, and 100G. The default dynamic shared buffer threshold value is 8.

Configure queue buffer settings

  1. Create queuing type class-map to match the queue.
    OS10(config)# class-map type queuing q1
                                        OS10(config-cmap-queuing)# match queue 1
  2. Create queuing type policy-map to define the actions for queues, like buffer configuration and thresholds.
    OS10(config)# policy-map type queuing q-buffer
                                        OS10(config-pmap-queuing)# class q1
                                        OS10(config-pmap-c-que)# queue-limit queue-len 200 thresh-mode dynamic 5
