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.
