Table 28 Port storm constrain configuration items
Item Remarks
Control Mode
Specify the action to be performed when a type of traffic exceeds the corresponding
upper threshold. Available options include:
 None—Performs no action.
 Block—Blocks the traffic of this type on a port when the type of traffic exceeds the
upper threshold.
 Shutdown—Shuts down the port when a type of traffic exceeds the traffic
threshold. The port stops forwarding traffic as a result.
IMPORTANT:
The storm constrain function, after being enabled, requires a full traffic statistics
generating interval (in seconds) to collect traffic data, and analyzes the data in the next
interval. It is normal that a period longer than one traffic statistics generating interval is
waited for a control action to happen if you enable the function while the packet storm
is present. Nevertheless, the action will be taken within two intervals.
Broadcast Threshold Set the broadcast, multicast, and unicast thresholds.
 None—Performs no storm constrain for the selected port or ports.
 pps—Specifies the storm constrain upper threshold and lower threshold in packets
per second (pps).
IMPORTANT:
 On a port, you can set the thresholds for broadcast, multicast, and unicast traffic
at the same time. To set storm constrain on a port successfully, you must specify the
thresholds for at least a type of traffic.
 When the pps option is selected, the upper threshold and lower threshold ranges
depend on the interface type, as shown in the pps range description on the page.
