DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide Storm Control Commands 58-1 storm-control This command is used to enable the storm suppression. Use the no form of the command to disable the storm suppression. storm-control {broadcast | multicast | unicast} {pps pps-rise [pps-low] | level level-rise [level-low]} no storm-control {broadcast | multicast | unicast} Parameters broadcast multicast unicast pps pps-rise {pps-low} level level-rise {level-low} Specifies to enable the broadcast storm suppression function on the port. Specifies to enable the multicast storm suppression function on the port. Specifies to enable the unknown unicast storm suppression function on the port. Specifies the threshold as packet count per second at which traffic is received on the port. The range is 1 to 14881000. Specifies the threshold as a percentage of total bandwidth per port at which traffic is received on the port. The range is 1 to 100. Default Command Mode Command Default Level Usage Guideline The default setting of broadcast, multicast, and unicast storm control are disabled. Interface Configuration Mode. Level: 15 Too many broadcast, multicast or unknown unicast packets received on a port may cause storm and thus slow network. A device can implement the storm suppression to a broadcast, a multicast, or a unicast storm respectively. When excessive broadcast, multicast or unknown unicast packets are received, the switch temporarily prohibits forwarding of relevant types of packets until data streams are recovered to the normal state (then packets will be forwarded normally). The low threshold must be equal to or less than the rise threshold suppression value. If don't configure the low threshold, it default equal to rise threshold. Use show storm-control to display configuration. Use storm-control action to config action. Note: 1. The storm-control option is not supported on a link aggregation port. 2. The level-based storm control option has certain errors for the packets in the length of more than 64 bytes. The longer the packet length is, the greater the comparable error value is. Example This example shows how to enable the multicast storm suppression on port 1 with a 1000 pps rising suppression and a 500 pps falling suppression.
