Re-map protocols to queues

On switches that have a fewer number of queues, multiple protocols are mapped to a single queue. OS10 allows you to re-map the protocols to available queues depending on your needs.

NOTE: This feature is not supported on the S4200-ON and S5100-ON series platforms.

For example, if your deployment does not need multicast protocols, re-map the multicast protocols to another queue. And use the original multicast queue, queue 2 for other protocols or applications that you need.

If the protocols or applications that your deployment needs share the same queue, re-map some of them to other queues that are mapped to protocols or applications that are not required.

If your deployment uses only a few protocols or applications, you can re-map these protocols or applications to individual queues. Also, you can change the buffer settings for the remaining queues that are mapped to unused protocols or applications. Ensure that you transfer the allocated buffer space from such queues to the common pool, which is used for lossy or lossless traffic.

If you re-map the protocols or applications to different queues when the system is operational, then until queue transition completes, egress traffic flows through queue 0.

The following show commands display protocol-to-queue mapping:

  • show control-plane info default — Displays the default protocol-to-queue mapping.
  • show control-plane info — Displays the currently configured protocol-to-queue mapping.
NOTE: You cannot re-map protocols and applications to queues that are mapped to CPS, port security, and Precision Time Protocol (PTP):
  • CPS —Queue 19
  • Port security—Queue 23
  • PTP —Queue 24

The following error message appears when you re-map protocols, applications, or both to an invalid queue: 

% Error: QOS : Invalid copp protocol queue mapping
