Storm-Constrain Control - H3C s3600 series Command Manual

storm-constrain control

Syntax
storm-constrain control { block | shutdown }
undo storm-constrain control
View
Ethernet port view
Parameters
block: Blocks and stops forwarding those types of traffic exceeding the upper thresholds.
shutdown: Shutdowns the port if the broadcast/multicast/unicast traffic exceeds the upper threshold,
and stops receiving and forwarding all types of traffic on the port.
Description
Use the storm-constrain control command to set the action to be taken when the
broadcast/multicast/unicast traffic on the port exceeds the upper threshold.
Use the undo storm-constrain control command to cancel the configured action.
By default, no action is taken.
If the fabric function is enabled on a port of a device, you cannot configure the storm control
function on all ports of the device.
If the broadcast-suppression command, multicast-suppression command or unicast
suppression command is configured on a port, you cannot configure the storm control function on
the port, and vice versa.
You are not recommended to set the upper and lower traffic thresholds to the same value.
The system can take one of the actions when the broadcast/multicast/unicast traffic received on a
port exceeds the upper threshold: block and shutdown. The block action blocks only those types
of traffic that exceed the upper thresholds instead of all types of traffic. When a type of traffic is
blocked, it is still counted by the system and contained in the traffic statistics. The shutdown action
automatically shutdowns the port when a type of traffic on the port exceeds the upper threshold. If
you want to bring up the port again, you can execute the undo shutdown command or the undo
storm-constrain { all | broadcast | multicast | unicast } command.
