Definition

 

 

 

 

<normal-

The maximum size of burst that is guaranteed transfer. Bursts that

 

burst>

are smaller than this size are guaranteed transfer. Bursts that are

 

 

 

larger than this size are either serviced by WFQ or dropped

 

 

 

(whichever action that you specify). The default setting is

 

 

 

servicing by WFQ and the default weight for the queues.

 

 

 

The normal burst can range from 0 to 15,000 bytes. Avaya

 

 

 

recommends a value of 6000.

 

 

 

Enter this setting in a multiple of four. If you do not enter a

 

 

 

multiple of four, the switch rounds down the number that you enter

 

 

 

to a multiple of four. For example, if you enter a normal burst size

 

 

 

of 43 byes, the switch converts the setting to 40 bytes. If you enter

 

 

 

a normal burst size of 0,1,2 or 3, the switch stores a value of 0 and

 

 

 

no data is forwarded from the queue.

 

 

 

 

exceed

The action that you want the switch to take if the bit rate exceeds

 

 

 

the guaranteed bit rate that you specify. The switch can either drop

 

 

 

packets or forward them based on the weight of the queue.

 

 

 

 

 

drop

 

Indicates that you want the switch to drop packets when the bit

 

 

 

rate exceeds the guaranteed bit rate.

 

 

 

 

<max-burst>

The maximum size burst that is serviced by WFQ once the normal

 

 

 

burst has been exceeded. Bursts that are smaller than this size are

 

 

 

serviced by WFQ. Bursts that are larger than this size are dropped.

 

 

 

If you set this threshold to the same value as normal burst, the

 

 

 

maximum burst capability is disabled.

 

 

 

The maximum burst can range from the normal burst size to

 

 

 

15,000.Avaya recommends a value of 6000.

 

 

 

Increase the maximum burst setting as the burstiness of the traffic

 

 

 

increases.

 

 

 

Note: The maximum burst setting must be greater than or equal to

 

 

 

the normal burst.

 

 

 

Enter this setting in a multiple of four. If you do not enter a

 

 

 

multiple of four, the switch rounds down the number that you enter

 

 

 

to a multiple of four. For example, if you enter a maximum burst

 

 

 

size of 43 byes, the switch converts the setting to 40 bytes.If you

 

 

 

enter a maximum burst size of 0,1,2 or 3, the switch stores a value

 

 

 

of 0 and no data is forwarded from the queue.

 

 

 

 

<weight>

The weight that you want to assign to the queue. Weights can

 

 

 

range from 1to 254.
