Manage broadcast filtering and set port storm control rate limits A broadcast storm is a massive transmission of broadcast packets that are forwarded to every port on the switch. If they are not blocked, broadcast storm packets can delay or halt the transmission of other data and cause problems. However, you can block broadcast storms on the switch. You can also set storm control rate limits for each port. Storm control measures the incoming broadcast, multicast, and unknown unicast frame rates separately on each port, and discards the frames if the rate that you set for the port is exceeded. By default, no storm control rate limit is set for a port. You can select each storm control rate limit as a predefined data transfer threshold from 512 Kbps to 512 Mbps.
