Configuring Bandwidth

The Bandwidth page enables users to define two values, Ingress Rate Limit and
Egress Shaping Rate, which determine how much traffic the system can receive
and send.
The ingress rate limit is the number of bits per second that can be received from
the ingress interface. Excess bandwidth above this limit is discarded.
The following values are entered for egress shaping:
• 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 Size (CBS) is the 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 enter bandwidth limitation:
Click Quality of Service > General > Bandwidth.
The Bandwidth page displays bandwidth information for each interface.
The % column is the ingress rate limit for the port divided by the total port
bandwidth.
Select an interface, and click Edit.
Select the Port or LAG interface. 500 series switches also have an option to
select Unit/Port.
Enter the fields for the selected interface:
• Ingress Rate Limit—Select to enable the ingress rate limit, which is defined
in the field below.
• Ingress Rate Limit—Enter the maximum amount of bandwidth allowed on
the interface.
The two Ingress Rate Limit fields do not appear when the interface

type is LAG.
