|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.

Description
Use display storm-constrain to display storm control settings and statistics.
If you specify no argument or keyword, this command displays all storm control settings on all storm control-enabled interfaces.
When the port forwarding state transition counter (SwiNum) reaches 65535, it automatically wraps back to 0.

StormType | 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 | Protective action (block or shutdown) taken on the port when the upper threshold is reached. If you have not configured any protective action, N/A is displayed. |
Status | Packet forwarding status:
|
Trap | Status of the storm control threshold event trap switch:
