To disable storm control, use the no storm-control broadcast level, no storm-control multicast level,
or no storm-control unicast level interface configuration commands.
This example shows how to set the multicast storm control level at 70.5 percent on a port and to verify
the configuration:
Switch# configure terminal
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# storm-control multicast level 70.5
Switch(config-if)# end
Switch# show storm-control gigabitethernet2/0/1 multicast

This example shows how to disable the multicast storm control on a port:
Switch# configure terminal
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# no storm-control multicast level
Switch(config-if)# end

Purpose
Specify the multicast traffic suppression level for an interface as a
percentage of total bandwidth. The level can be from 1 to 100; the
optional fraction of a level can be from 0 to 99. A threshold value
of 100 percent means that no limit is placed on broadcast traffic. A
value of 0.0 means that all multicast traffic on that port is blocked.
Specify the unicast traffic suppression level for an interface as a
percentage of total bandwidth. The level can be from 1 to 100; the
optional fraction of a level can be from 0 to 99. A threshold value
of 100 percent means that no limit is placed on broadcast traffic. A
value of 0.0 means that all unicast traffic on that port is blocked.
Return to privileged EXEC mode.
Verify the storm control suppression levels set on the interface for
the specified traffic type. If you do not enter a traffic type,
broadcast storm control settings are displayed.
(Optional) Save your entries in the configuration file.
