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
