Switch(config)# interface gigabitethernet 2/1
Switch(config-if)# no storm-control broadcast level
Switch(config-if)# end
The following example shows how to disable storm control by setting the high level to 100 percent:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
