lengths of various queues, and the number of bytes that may be continuously
transmitted by polling of every queue.
The priority queue may be configured according to the following methods:
1 Configure the priority queue according to the network layer protocol
Based on packet length, TCP/UDP port number, whether or not matching ACL,
you can classify data packets, so that they can enter the queues with different
priority.
Perform the following configurations in system view.
Table 721 Configure the Priority Queue According to the Network Layer Protocol
Operation
Configure the priority queue according to
the network layer protocol
Delete the classification policy in the
priority queue
By default, no priority queue is established.
Among them, pql-index is the group number of the priority queue, and
protocol-name is the protocol name, the current value may be IP.
With protocol-name as IP, value of queue-option is listed in the following table:
Table 722 Values of Queue-Option with Protocol as IP
queue-option
Empty
acl acl-number (1∼ 199)
fragments
greater-than bytes (0∼ 65535)
less-than bytes (0∼ 65535)
tcp port (0∼ 6553)
udp port (0∼ 65535)
2 Configure the priority-list queuing according to the interface
The data packets can be classified according the different types of interfaces into
which the data packets are input, and be input into different priority queues.
Please perform the following configurations in the system view
Table 723 Configure the Priority-List Queuing According to the Interface
Operation
Configure the priority-list queuing
according to the interface
Configuring Congestion Management
Command
qos pql pql-index protocol
protocol-name queue-option queue {
top | middle | normal | bottom }
undo qos pql pql-index protocol
protocol-name queue-option queue {
top | middle | normal | bottom }
Meaning
All IP packets can be processed into queue
All IP packet fragments can be processed into
priority queue
IP packets defined by theacl-number (normal) can
be processed into priority queue
IP packet with a length less than a certain value can
be processed into queue
IP packet with a length greater than a certain value
can be processed into queue
With the source or destination TCP port of IP packet
being the specified port, the packet can be
processed into queue.
With the source or destination UDP port of IP
packet being the specified port, the packet can be
processed into priority queue.
Command
qos pql pql-index inbound-interface
interface-type interface-number
queue { top | middle | normal |
bottom }
