Usage Guidelines
The storm-control suppression level can be entered as a percentage of total bandwidth of the port, as a rate in
packets per second at which traffic is received, or as a rate in bits per second at which traffic is received.
When specified as a percentage of total bandwidth, a suppression value of 100 percent means that no limit is
placed on the specified traffic type. A value of level 0 0 means that all broadcast, multicast, or unicast traffic
on that port is blocked. Storm control is enabled only when the rising suppression level is less than 100 percent.
If no other storm-control configuration is specified, the default action is to filter the traffic causing the storm
and to send no SNMP traps.
When the storm control threshold for multicast traffic is reached, all multicast traffic except control traffic,
Note
such as bridge protocol data unit (BDPU) and Cisco Discovery Protocol (CDP) frames, are blocked.
However, the switch does not differentiate between routing updates, such as Open Shortest Path First
(OSPF) and regular multicast data traffic, so both types of traffic are blocked.
The trap and shutdown options are independent of each other.
If you configure the action to be taken as shutdown (the port is error-disabled during a storm) when a packet
storm is detected, you must use the no shutdown interface configuration command to bring the interface out
of this state. If you do not specify the shutdown action, specify the action as trap (the switch generates a trap
when a storm is detected).
When a storm occurs and the action is to filter traffic, if the falling suppression level is not specified, the
switch blocks all traffic until the traffic rate drops below the rising suppression level. If the falling suppression
level is specified, the switch blocks traffic until the traffic rate drops below this level.
Rising suppression level, up to 1 decimal place. The range is 0.0 to 10000000000.0.
Block the flooding of storm packets when the value specified for pps is reached.
You can use metric suffixes such as k, m, and g for large number thresholds.
(Optional) Falling suppression level, up to 1 decimal place. The range is 0.0 to
10000000000.0. This value must be equal to or less than the rising suppression value.
You can use metric suffixes such as k, m, and g for large number thresholds.
