    show ethernet-switching-options    
    storm-control {
        interface all {
            bandwidth 1000;


    this will control the input rate for each interface is 1000kbps,right?

    not for the output?

    Correct. Storm-control works only for the ingress traffic.

    whether 100kbs is sufficent in network for broadcast/unknown unicast /multicast(there should be no mc in our network)

    That depends on your traffic nature/patterns, really.
    I would suggest using wireshark and let it run for a couple of work-days. You can then make graphs on wireshark and check out the average/maximum traffic load for the ports; and then configure appropriate values.

    I missed one question how to check many storm exceeds the configured lmit,how to check the counter?

    To check the traffic ingressing the interface, you can use "show interfaces <int> extensive" command. It shows the ingress/egress rates for the interface.

    To check if a port has been error-disabled by storm-control, you can use "show ethernet-switching interfaces" command.

    In case you haven't configured the storm-control action to disable the port, then a syslog message should be generated reflecting that storm-control has started kicking in on the interface.
