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:
The following example shows how to enable multicast suppression on ports that have broadcast
suppression already enabled:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# int fa3/1
Switch(config-if)# storm-control broadcast include multicast
Switch(config-if)# end
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# interface interface-id
Enters interface configuration mode and enter the port to
configure.
Step 3
Switch(config-if)# storm-control
broadcast include multicast
Enables multicast suppression.
Step 4
Switch(config-if)# exit
Returns to configuration mode.
Step 5
Switch(config)# end
Returns to privileged EXEC mode.
Step 6
Switch# show storm-control
Verifies the configuration.
