Enabling Multicast Storm Control
Per-interface multicast suppression, which allows you to subject incoming multicast and broadcast
traffic to interface-level suppression.
Note Multicast and broadcast suppression share a common threshold per interface. Multicast suppression
takes effect only if broadcast suppression is enabled. Disabling broadcast suppression on an interface
also disables multicast suppression.
To enable multicast suppression, perform this task:
Command or Action Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# interface interface-id
Enters interface configuration mode and specifies the port to be
configured.
Step 3
Switch(config-if)# storm-control
broadcast include multicast
Enables multicast suppression.
Step 4
Switch(config-if)# exit
Returns to configuration mode.
