1828 CHAPTER 115: CBQ CONFIGURATION COMMANDS

In the policy the default class default-class cannot be associated with the traffic behavior queue ef belongs to.

The sum of the bandwidth specified for the classes in the same policy to assured forwarding (queue af) and expedited forwarding (queue ef) must be less than or equal to the available bandwidth of the interface where the policy is applied.

The sum of percentages of the bandwidth specified for the classes in the same policy to assured forwarding (queue af) and expedited forwarding (queue ef) must be less than or equal to 100.

The bandwidth configuration for the classes in the same policy to assured forwarding (queue af) and expedited forwarding (queue ef) must adopt the value of the same type. For example, they all adopt the absolute value form or the percentage form.

For the percentage form queue ef bandwidth pct percentage [ cbs-ratio ratio ],

CBS = Interface available bandwidth*percentage*ratio/100/1000

For the absolute value form queue ef bandwidth bandwidth [ cbs burst ], CBS = burst, or = bandwidth*25 if burst is not specified.

Examples # Configure packets to enter priority queue. The maximum bandwidth is 200 kbps and CBS is 5000 bytes.

queue wfq

Syntax queue wfq [ queue-number total-queue-number]

undo queue wfq

View Traffic behavior view

Parameters total-queue-number: Number of fair queue, which can be 16, 32, 64, 128, 256, 512, 1024, 2048 and 4096 and the default value is 64.

Description Use the queue wfq command to configure the default-class to use WFQ.

Use the undo queue wfq command to delete the configuration.

The traffic behavior configured with the command can only be associated with the default class. It can also be used together with the command like queue-lengthor wred.
