Rate Limiting Configuration

The Rate Limiting Configuration screen (Figure 3-14) allows you to limit the forwarding rate of broadcast and multicast packets.

You can use this screen to view the percentage of broadcast packets and multicast packets received, on a per-port basis. When the volume of broadcast and multicast packets is high (often referred to as a “storm”) and places severe strain on the network, you can set the forwarding rate of those packet types to not exceed a specified percentage of the total available bandwidth.

Note: The BayStack Model 350F Rate Limiting Configuration screen displays only 14 ports.
