M5300, M6100, and M7100 Series ProSAFE Managed Switches storm-control unicast This command enables unicast storm recovery mode for all interfaces (Global Config mode) or one or more interfaces (Interface Config mode). If the mode is enabled, unicast storm recovery is active, and if the rate of unknown L2 unicast (destination lookup failure) traffic ingressing on an interface increases beyond the configured threshold, the traffic will be dropped. Therefore, the rate of unknown unicast traffic will be limited to the configured threshold. Default Format Mode disabled storm-control unicast Global Config Interface Config no storm-control unicast This command disables unicast storm recovery mode for all interfaces (Global Config mode) or one or more interfaces (Interface Config mode). Format Mode no storm-control unicast Global Config Interface Config storm-control unicast level This command configures the unicast storm recovery threshold for all interfaces (Global Config mode) or one or more interfaces (Interface Config mode) as a percentage of link speed, and enables unicast storm recovery. If the mode is enabled, unicast storm recovery is active, and if the rate of unknown L2 unicast (destination lookup failure) traffic ingressing on an interface increases beyond the configured threshold, the traffic will be dropped. Therefore, the rate of unknown unicast traffic will be limited to the configured threshold.This command also enables unicast storm recovery mode for an interface. The threshold level can be in the range from 0-100. The default is 5. Default Format Mode 5 storm-control unicast level threshold Global Config Interface Config Switching Commands 464

M5300, M6100, and M7100 Series ProSAFE Managed Switches

storm-control unicast

This command enables unicast storm recovery mode for all interfaces (Global Config mode)

or one or more interfaces (Interface Config mode). If the mode is enabled, unicast storm

recovery is active, and if the rate of unknown L2 unicast (destination lookup failure) traffic

ingressing on an interface increases beyond the configured threshold, the traffic will be

dropped. Therefore, the rate of unknown unicast traffic will be limited to the configured

threshold.

no storm-control unicast

This command disables unicast storm recovery mode for all interfaces (Global Config mode)

or one or more interfaces (Interface Config mode).

storm-control unicast level

This command configures the unicast storm recovery threshold for all interfaces (Global

Config mode) or one or more interfaces (Interface Config mode) as a percentage of link

speed, and enables unicast storm recovery. If the mode is enabled, unicast storm recovery is

active, and if the rate of unknown L2 unicast (destination lookup failure) traffic ingressing on

an interface increases beyond the configured threshold, the traffic will be dropped. Therefore,

the rate of unknown unicast traffic will be limited to the configured threshold.This command

also enables unicast storm recovery mode for an interface. The threshold level can be in the

range from 0–100. The default is 5.
