Enabling and Disabling Multicast Rate Limiting

Multicast rate limiting is used to minimize the effects of multicast storms. You can restrict multicast storms, consisting of packets that have a specific destination MAC address, to that segment of the network from which the packets are generated. You do so by setting the maximum number of those packets the line card is to forward per second, and by enabling rate limiting.

Rate limiting is enabled on both a per-address basis and a line card-wide basis. This section provides instructions about how to enable or disable rate limiting on a per MAC address basis.

See Enabling and Disabling line card-wide Rate Limiting for information about setting the maximum number of packets per second and enabling or disabling rate limiting on a line card-wide basis.
