Hii Experts,


Wht is the command to stop the Broadcast traffic from remote site connected on Switch Port (L2 port).

Hi,


Storm-Control can be used to limit, or to set thresholds for different types of traffic (Broadcast, Multicast and Unicast) on a specific interface you choose (or that you´re asked for).You can set your threshold to whatever the top level that you want, and the traffic will be limit to that.


The following example will enable Unicast Storm-Control on a switch port with an 89% rising suppression level and a 67% falling suppression (remember, falling suppression can only be configured in 3560). It´ll also enable Broadcast Storm-Control on a port to a level of 20%. When the Broadcast exceeds the configured level of 20% of the total available bandwidth of the port within the traffic-storm-control interval, the switch drops all broadcast traffic until the end of the traffic-storm-control interval:


interface gigabitethernet0/1
storm-control unicast level 89 67
storm-control broadcast level 20


Hope to Help !!

Hi Ganesh & Guise,



Implemented the command on L3 switch gig interface (Cisco 4500 series).


interface GigabitEthernet4/36
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 2,4,6
switchport mode trunk
speed 100
duplex full
udld port aggressive
storm-control broadcast level 0.00


We have given Level % "0",  As per understanding If we configure the 0% level then there should not be any single broadcast on the interface. But even after this we are getting broadcast on the interface.



5 minute input rate 807000 bits/sec, 326 packets/sec
5 minute output rate 2729000 bits/sec, 391 packets/sec
    5514045 packets input, 1802450404 bytes, 0 no buffer
    Received 1712 broadcasts (1109 multicast)
    0 runts, 0 giants, 0 throttles
    0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
    0 input packets with dribble condition detected



Please help to stop the total broadcast on Gig.
