Field Description
Flow Statistic Interval The traffic polling interval of the storm control module.
PortName Abbreviated port name
Type
Type of traffic subjected to storm control. Options include broadcast, multicast
and unknown unicast.
LowerLimit Lower storm control threshold, in pps, kbps, or percentage.
UpperLimit Upper storm control threshold, in pps, kbps, or percentage.
CtrMode

which can be block or shutdown. If you have not configured any protective
action, N/A is displayed.
Status
Packet forwarding status, which may be one of the following:

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.
Swinum
Number of times the forwarding state of the interface changes.
When the
