Volume 10-Network Management / Chapter 56-Traffic Storm Control Traffic Storm Configuration Commands forever mode, if the receiving rate is higher than the falling threshold (80% of threshold) the port will be recovered immediately. If the port is in block state, the traffic rate has become higher than the threshold for a configurable period (countdown timer), the port will go into shutdown forever mode (the port is disabled, the state is link down). The user can define the recovery time, if the recovery times value is non-zero, the port will automatically recover, entering a state that is the same as the normal situation (after recovery time). If recovery times are not set the port will not be automatically recovered. it can instead be recovered by "no shutdown" command. NOTE: The traffic storm control function is disabled by default. Traffic Storm Configuration Commands Configuring the Traffic Storm Control Timer The traffic storm control features uses a number of timers to implement the shutdown action that will be taken. The following command is used to configure the storm control timer options: Command storm-control {time-interval SECONDS | countdown SECONDS | recover-time SECONDS} Explanation Specifies the storm control timer options. In the following example, the user configures the amount of time that the software will monitor the counters for all traffic storm traffic to be 15 seconds, the amount of time that the port will remain in shutdown mode to be 180 seconds, and specifies that port will automatically recover after 300 seconds when it is in shutdown forever mode: DGS-6600:2>enable DGS-6600:15#configure terminal DGS-6600:15(config)#storm-control time-interval 15 DGS-6600:15(config)#storm-control countdown 180 DGS-6600:15(config)#storm-control recover-time 300 DGS-6600:15(config)#end Enabling Traffic Storm Control on an Interface After configuring the global traffic storm control settings, the user needs to select the interfaces that the traffic storm control feature will be enabled on DGS-6600 Configuration Guide 550
