threshold on an interface, the traffic is dropped.
• Multicast. If the rate of incoming Layer 2 multicast traffic increases beyond the
configured threshold on an interface, the traffic is dropped.

configured threshold on an interface, the traffic is dropped.

Disabled, specify whether the ingress control mode is enabled by selecting Enable or
Disable from the Status menu.
