Null

If it is an IPX packet, it enters the queue

 

 

 

lt

Length Value

IPX packet whose length is smaller than a count value enters the priority

queue.

 

 

gt

Length Value

IPX packet whose length is larger than a count value enters the priority

queue.

 

 

2)Configure the priority queue according to the interface

Data packet is classified by the interface through which it enters, and is accordingly put into queue with different priority.

Perform the following task in the global configuration mode.

Table QC-3-5Configuring priority queue according to the interface

Operation

Command

 

 

Configure the priority queue according to

priority-list list-numberinterface type number { high medium

the interfaces

normal low }

Delete classification policies in the priority

no priority-list list-numberinterface type number {high medium

queue

normal low }

No priority queue is established by default.

3)Configure the default queue

Packets not in compliance with any matching policy in the priority queue should be allocated to a default priority queue.

Perform the following task in the global configuration mode.

Table QC-3-6Configuration the default priority queue

Operation

Command

 

 

Configure the default priority queue

priority-list list-numberdefault { high medium normal low }

Restore the default priority of the priority

no priority-list list-numberdefault

queue

 

No priority queue is established by default.

Multiple policys can be defined for a group of the priority queue, and this group can be applied to a certain interface. When a packet reaches this interface (then sent out from this interface), the system matches this packet along the policy link. If the packet is matched with a certain policy, it enters the corresponding queue, and the matching is completed. If the packet does not match with any policy, it enters the default queue. The default priority of the priority queue is normal.

4)Specify the queue length of the priority queue (optional)

The queue length in each priority queue can be specified (the queue length refers to the maximum number of packets that can be accommodated in a queue).

Perform the following task in the global configuration mode.
