Configuring Storm Control Chapter 19 Configuring Port-Based Traffic Control Step 3 Command storm-control {broadcast | multicast | unicast} level {level [level-low] | bps bps [bps-low] | pps pps [pps-low]} Step 4 storm-control action {shutdown | trap} Step 5 end Purpose Configure broadcast, multicast, or unicast storm control. By default, storm control is disabled. The keywords have these meanings: • For level, specify the rising threshold level for broadcast, multicast, or unicast traffic as a percentage (up to two decimal places) of the bandwidth. The port blocks traffic when the rising threshold is reached. The range is 0.00 to 100.00. • (Optional) For level-low, specify the falling threshold level as a percentage (up to two decimal places) of the bandwidth. This value must be less than or equal to the rising suppression value. The port forwards traffic when traffic drops below this level. If you do not configure a falling suppression level, it is set to the rising suppression level. The range is 0.00 to 100.00. If you set the threshold to the maximum value (100 percent), no limit is placed on the traffic. If you set the threshold to 0.0, all broadcast, multicast, and unicast traffic on that port is blocked. • For bps bps, specify the rising threshold level for broadcast, multicast, or unicast traffic in bits per second (up to one decimal place). The port blocks traffic when the rising threshold is reached. The range is 0.0 to 10000000000.0. • (Optional) For bps-low, specify the falling threshold level in bits per second (up to one decimal place). It can be less than or equal to the rising threshold level. The port forwards traffic when traffic drops below this level. The range is 0.0 to 10000000000.0. • For pps pps, specify the rising threshold level for broadcast, multicast, or unicast traffic in packets per second (up to one decimal place). The port blocks traffic when the rising threshold is reached. The range is 0.0 to 10000000000.0. • (Optional) For pps-low, specify the falling threshold level in packets per second (up to one decimal place). It can be less than or equal to the rising threshold level. The port forwards traffic when traffic drops below this level. The range is 0.0 to 10000000000.0. For BPS and PPS settings, you can use metric suffixes such as k, m, and g for large number thresholds. Specify the action to be taken when a storm is detected. The default is to filter out the traffic and not to send traps. • Select the shutdown keyword to error-disable the port during a storm. • Select the trap keyword to generate an SNMP trap when a storm is detected. Return to privileged EXEC mode. 19-4 Catalyst 2960 Switch Software Configuration Guide OL-8603-04
