Table 9: Command output

Field	Description
Flow Statistic Interval	Traffic polling interval (in seconds) of the storm control module.
Port	Abbreviated port name.
Type	Type of traffic subjected to storm control: BC—Broadcast packets. MC—Multicast packets. UC—Unknown unicast packets.
Lower	Lower storm control threshold, in pps, kbps, or percentage.
Upper	Upper storm control threshold, in pps, kbps, or percentage.
Unit	Storm control threshold unit: pps. kbps. percentage.
CtrlMode	Protective action (block or shutdown) taken on the port when the upper threshold is reached. N/A indicates that no protective action is configured.
Status	Packet forwarding status: FW—The port is forwarding traffic correctly. shutdown—The port has been shut down. block—The port drops the type of traffic.
Trap	Status of the storm control threshold event trap switch: on—The port sends threshold event traps. off—The port does not send threshold event traps.
Log	Status of the storm control threshold event log switch: on—The port sends threshold event log messages. off—The port does not send threshold event log messages.
SwitchNum	Number of forwarding state changes of the interface. When the SwitchNum count reaches 65535, it resets automatically.
