queue-length is the queues lengths of the 4 priority levels. They range 1 to 1024
packets.
The default length of each priority queue is shown in the following table:

Queuing (CQ)
Custom queuing configuration includes:
■
Configuring custom-list queuing
■
Applying the custom-list queuing group to the interface
■
Configuring the queue length of the custom-list queuing
■
Configuring the number of the continuously transmitted bytes of the custom
queue
■
Displaying and debugging the custom-list queue
Configuring custom-list queuing
Custom queuing includes up to 16 groups (the value range of cql-index is 1 to 16),
each of which specifies which types of data packets are input to each queue, the
lengths of various queues, and the number of bytes that can be continuously
transmitted by polling every queue. Every time the packets are transmitted, the
packets in queues 1 to 16 are transmitted sequentially, and the number of the
transmitted bytes for every transmission is not less than the number of the
specified bytes in this queue, until this queue is empty.
Multiple custom queues can be configured, and the data packet will be matched
by the system according to the specified sequence order in the policy list. If it is
found that the data packet is matched with a policy, the entire searching process
comes to an end.
The custom queue may be configured according to the following methods:
