Storm-Constrain Enable - H3C s3100 series Command Manual

If the broadcast-suppression command, or multicast-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 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 } command.
