Configuring Storm Control on an Ethernet Interface

  1. Enter global configuration mode.
    device# configure terminal
    
  2. Specify the Ethernet interface for the traffic you want to control.
    device(config)# interface ethernet 2/2
    
  3. Specify a traffic limit for broadcast traffic on the interface.
    device(conf-if-eth-2/2)# storm-control ingress broadcast limit-bps 400000
    

    This example controls the inbound broadcast traffic, limiting the rate to 400000 bits per second (bps).

  4. Specify a traffic limit for unknown-unicast traffic on the interface.
    device(conf-if-eth-2/2)# storm-control ingress unknown-unicast limit-bps 50000000
    
    This example controls the inbound unknown-unicast traffic, limiting the rate to 50000000 bps.
  5. Specify a traffic limit for multicast traffic on the interface.
    device(conf-if-eth-2/2)# storm-control ingress multicast limit-percent 3   
    
    This example controls the inbound multicast traffic, limiting the rate to 3% of traffic.
  6. Return to privileged EXEC mode.
    device(conf-if-eth-2/2)# end
    
  7. Verify the storm control configuration.
    device# show running-config interface ethernet 2/2 | include storm-control
     storm-control ingress broadcast limit-bps 400000 
     storm-control ingress multicast limit-percent 3 
     storm-control ingress unknown-unicast limit-bps 50000000 
    
  8. Save the configuration.
    device# save running-config startup-config
