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.

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

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.

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-length 
or wred.
