Configuring Rate Control Settings for an Interface

To configure rate control settings or to enable flow control, complete the following steps:

1	On the Switching > Rate Control page, click the Configure icon in the row for the interface you want to configure. The Edit Rate Control Settings window opens.

2	To enable flow control on this interface, select Enable Flow Control. This check box is deselected by default.

3	To set the mode for limiting the bandwidth of ingressing frames, select one of the following from the Ingress Mode drop-down list:

•

Limit All

•	Limit Broadcast, Multicast and Flooded Unicast — this is the default mode

•	Limit Broadcast and Multicast

•	Limit Only Broadcast

4

Type the desired ingress rate limit in kilobits per second into the Ingress Rate field. The default ingress rate limit is 256Kbps. To turn off the ingress rate limit and allow unlimited traffic, type 0 (zero). The value you type will be rounded to the nearest increment, depending on the granularity available for that rate. The granularities are different depending on the range of rates:

•	128kbps ~ 1Mbps – increments of 64kbps

•	1Mbps ~ 100Mbps – increments of 1Mbps

•	100Mbps ~ 1000Mbps – increments of 10Mbps (for gigabit ports)

5

Type the desired egress rate limit in kilobits per second into the Egress Rate field. The default egress rate limit is 0Kbps. To turn off the egress rate limit and allow unlimited traffic, type 0 (zero). The value you type is rounded to the nearest increment, depending on the granularity available for that rate. The granularities are the same as for the ingress rate.
