If protocol-name is IPX, the value of queue-keyword and keyword-value is shown in the
table below.
Table QC-3-4 Value of queue-keyword and keyword-value in IPX
queue-keyword keyword-value Meaning
Null 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 en ters, and is accordingly put
into queue with different priority.
Perform the following task in the global configuration mode.
Table QC-3-5 Configuring priority queue according to the interface
Operation Command
Configure the priority queue according to
the interfaces priority-list list-number interface type number { high | medium |
normal | low }
Delete classification policies in the priority
queue no priority-list list-number interface type number {high | medium |
normal | low }
No priority queue is established by default.
3) Configure the default queue
Packets not in compliance with any matching policy in the priorit y queue should be
allocated to a default priority queue.
Perform the following task in the global configuration mode.
Table QC-3-6 Configuration the default priority queue
Operation Command
Configure the default priority queue priority-list list-number default { high | medium | normal | low }
Restore the default priority of the priority
queue no priority-list list-number default
No priority queue is established by default.
Multiple policys can be defined for a group of the priority queue, and this group ca n 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.
