Configuring Bandwidth
The
Bandwidth
page enables network managers to define two sets of values,
Ingress Rate Limit and Egress Shaping Rate, that 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:
