Setting The Port State Change Delay - H3C S3100-52P Operation Manual

Operation Manual – Port Basic Configuration
H3C S3100-52P Ethernet Switch
Set the action to be taken
when a type of traffic
received on the port
exceeds the upper
threshold.
Enable log/trap information
to be output when a type of
traffic received on the port
exceeds the upper
threshold or falls below the
lower threshold
Return to system view
Set the interval at which the
port collects traffic statistics
Note:
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.
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.

1.1.13 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.
To do...
storm-constrain control
{ block | shutdown }
storm-constrain enable
{ log | trap }
quit
storm-constrain interval
