Configuration task of custom queuing is as follows:
z Configure the custom queue

II. Configuring the custom queue
16 groups can be configured in the custom queue at most (that is, the value range of
the list-number is 1-16). In each group, the following information is specified: what kind
of packets enters what kind of queue, length of each queue, the number of the bytes
that can be sent continuously from the respective queues in each polling, etc. Each
time packets of No.1-16 queues are sent in turn. The number of bytes sent each time
cannot be less than the number defined by the queue, and packets will be sent out until
the queue is empty.
Multiple priority queues can be configured. The system will match the packets
according to the sequence specified in the policy list. If the system finds that the packet
matches with a policy, it ends the whole searching process.
Custom queue can be configured according to the modes below.
1) Configure the custom queue according to the network layer protocol
Packets can be classified according to the different protocol types, and make them
enter the queues with different custom priority.
Perform the following task in the global configuration mode.
