Using the BCC

To enable traffic shaping, you configure the following parameters:

normal-queue-limit, high-queue-limit, low-queue-limit, committed-burst,

excess-burst, and throughput.

Normal, High, and Low Queue Limits

There are three queue limits for traffic shaping: the normal queue, the high queue,

and the low queue. You can configure these queue limits for a frame relay

interface and a PVC.

The interface queue limit is the total number of buffers that all traffic shaped

PVCs in the interface’s service records may place in a specific queue.

The PVC queue limit specifies the maximum number of buffers that traffic-shaped

PVCs may place in a specific queue.

To change a queue limit, navigate to the interface prompt (for example,

box;

serial/1/2; frame-relay/1/2

) or the appropriate PVC prompt (for example,

box;

serial/1/2; frame-relay/1/2; boston; pvc/1/2/51

) and enter one of the following

commands:

normal-queue-limit

high-queue-limit

low-queue-limit

integer

can be a value from 0 to 5000.

The default for the interface is 30. The default value for the PVC is 0, inherit,

which means that the PVC uses the interface’s queue limit value.

Dividing the interface’s queue limit by the number of traffic-shaped PVCs gives

you the number of buffers that the PVC can place into the designated queue. If

you set the limit to a value other than 0, that value is the number of buffers that the

PVC can place into the queue.

For example, to set an interface normal queue limit of 100, navigate to the

interface prompt and enter:

frame-relay/1/2#

normal-queue-limit 100

frame-relay/1/2

1 2 ... 99 100 101 102 103 104 105 106 107 108 109 ... 245 246
