storm-control broadcast include multicast
To enable multicast storm control on a port, use the storm-control broadcast include multicast
command. To disable multicast storm control, use the no form of this command.
Syntax Description
This command has no arguments or keywords.
Command Default Multicast storm control is disabled.
Command Modes Global configuration mode (config)
Interface configuration mode on Catalyst 4900M, Catalyst 4948E, Catalyst 4948E-F, Supervisor Engines
6-E, 6L-E, 7-E, 7L-E, and 8-E.
Command History Release
12.2(18)EW
12.2(40)SG
3.8.0E and 15.2.(4)E
Usage Guidelines
This command prompts the hardware to filter multicast packets if it is already filtering broadcast packets.
When you specify threshold levels for traffic as a percentage of the bandwidth or in bps, the traffic that
is suppressed is a combined rate of multicast and broadcast traffic that exceeds the threshold (if the
action is filtering).
When you specify threshold levels for traffic in pps, the rate at which traffic is suppressed is considered
separately for broadcast and multicast traffic, and the storm action (if the action is filtering) is taken
separately.
The switch supports per-interface multicast suppression. When you enable multicast suppression on an
interface, you subject incoming (multicast and broadcast) traffic on that interface to suppression.
Examples The following example shows how to enable multicast storm control globally:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# storm-control broadcast include multicast
Switch(config)# end
The following example shows how to enable per-port Multicast storm control on a Supervisor Engine
6-E:
storm-control broadcast include multicast
no storm-control broadcast include multicast
