When queue-key is tcp or udp, key-value can be port name or the associated port 
number.

Use the qos pql protocol command to establish classification rules based on the 
protocol type.

Use the undo qos pql protocol command to delete the corresponding 
classification rule.

By default, no rule is set.

The system matches a packet to a rule according to the set order. When the 
packet matches a certain rule, the search process is completed.

For the same pql-index, this command can be repeatedly used, establishing 
multiple classification rules for IP packets.

qos pql default-queue, qos pql inbound-interface, qos pql queue, qos pq.

# Specify PQ group number to 1 to make IP packets matching ACL 3100 be put 
into the top queue.

Length, 0 to 65535 

Any link layer frame greater than the specified 
value is enqueued.

Port number, 0 to

Any IP packet whose source or destination TCP 
port number is the specified port number will be 
classified.

Port number, 0 to 
65535 

Any IP packet whose source or destination UDP 
port number is the specified port number will be 
classified.
