Configuring CQ
CQ is configured by assigning protocols or port numbers to a queue in the queue list by using
the queue-list command. A byte count is applied to each queue. Configure the queue list for the
interface by using the custom-queue-list command.

The syntax of the queue-list command to assign a protocol to a queue number is as follows:
queue-list list-number protocol protocol-name queue-number
queue-keyword keyword-value
The list number is from 1 to 16. The queue number is from 0 to 16.

The syntax of the queue-list command to configure the number of bytes per queue is as follows:

queue-list list-number queue queue-number byte-count num-bytes
The num-bytes is the size of bytes from 1 to 16777215.

Example 11-3 shows a sample configuration of CQ by using four queues.
