Bandwidth

The amount of traffic that can be received and transmitted on an interface

can be limited by the following:

Ingress Rate Limit — Number of bits per second that can be received

from the ingress interface. Excess bandwidth above this limit is discarded.

Egress Shaping Rates is defined by the following:

Committed Information Rate (CIR) sets the average maximum

amount of data allowed to be sent on the egress interface, measured in

bits per second

Committed Burst Shape (CBS) sets the maximum burst of data that

is allowed to be sent, even though it is above the CIR. This is defined

in number of bytes of data.

To configure bandwidth limitation:

1 Click Quality of Service > General > Bandwidth in the tree view to

display the Bandwidth: Summary page.
The ingress and egress rates are displayed for all ports on the selected unit.

2 To set interface parameters, click Edit.
3 Select an interface, and enter the fields:

Enable Ingress Rate Limit — Enable/disable ingress traffic limit for

the interface. If this field is selected, enter the Ingress Rate Limit.

Ingress Rate Limit — Enter the ingress traffic limit for the interface.

Enable Egress Shaping Rate — Enable/disable egress traffic

limitation. If this field is selected, enter the following fields.

Committed Information Rate (CIR) — Enter the average maximum

amount of data allowed to be sent on the egress interface, measured in

bits per second.

Committed Burst Size (CBS) — Enter the maximum burst of data

that is allowed to be sent on the egress interface, even though it is

above the CIR. This is defined in number of bytes of data.
