top, middle, normal and bottom: Corresponds to the four levels of priority 
queue, in descending order. The queue defaults to normal.

Use the qos pql default-queue command to designate the packets without 
corresponding rules to a default queue.

Use the undo qos pql default-queue command to cancel the configuration 
and restore the default value.

During traffic classification, if a packet does not match any rule, it will be put into 
the default priority queue.

For the same pql-index, repeated use of this command will set new default queue.
