block: Blocks the traffic of a specific type on a port when the traffic detected exceeds the upper 

threshold. 

shutdown: Shuts down a port when a type of traffic exceeds the corresponding upper threshold. A port 

shut down by the storm constrain function stops forwarding all types of packets. 

Use the storm-constrain control command to set the action to be taken when a type of traffic exceeds 

the corresponding upper threshold. 

Use the undo storm-constrain control command to restore the default. 

By default, no action is taken when a type of traffic exceeds the corresponding threshold.

Use the storm-constrain enable log command to enable log sending. With log sending enabled, the 

system sends log when traffic reaching a port exceeds the corresponding threshold or the traffic drops 

down below the lower threshold after exceeding the upper threshold. 

Use the undo storm-constrain enable log command to disable log sending. 

By default, log sending is enabled.
