z 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.
z 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.
z You are not recommended to set the upper and lower traffic thresholds to the same value.
z If you specify the block keyword when executing the storm-constrain control command, only the
packets beyond the upper thresholds are blocked when the overall traffic exceeds the upper
threshold. In this case, the blocked packets are still taken into account when generating traffic
statistics. If you specify the shutdown keyword when executing the command, the port will be shut
down when the traffic passing through the port exceeds the upper threshold. You bring up the port
again by executing the undo shutdown or the undo storm-constrain { all | broadcast |
multicast | unicast } command.
Setting the Port State Change Delay
During a short period after you connect your switch to another device, the connecting port may go up
and down frequently due to hardware compatibility, resulting in service interruption.
To avoid situations like this, you may introduce a port state change delay.
The port state change delay takes effect when the port goes down but not when the port goes up.
Follow these steps to set the port state change delay:
