DGS-6604 m storm-control timer (Global) storm-control timer (Global) Use this command to configure the timer options. The timers are used to implement a storm control shutdown action. Use the no form of the command to return the default settings. storm-control { time-interval SECONDS | countdown SECONDS | auto-recover-time SECONDS } no storm-control { time-interval | countdown | auto-recover-time} Syntax Description time-interval SECONDS Software will monitor the counter of received broadcast or multicast packets periodically based on this user defined interval. The range of the checking interval (SECONDS) is from 5 to 30 seconds. countdown SECONDS If a port is in shutdown mode and this timer runs out, the port will be placed in shutdown forever mode. If the value is '0' the function of shutdown forever is disabled. auto-recover-time SECONDS The valid range for this setting is 0, 180 - 1800 seconds. Specifies the time that a port is in shutdown forever mode, from which it can be automatically recovered. When the value is set to '0' a port cannot recover from forever shutdown. The valid range for this setting is 0, 300 - 1800 seconds. Default Command Mode Usage Guideline time-interval SECONDS: 5 seconds countdown time SECONDSr: 0 seconds auto-recover-time SECONDS: 0 seconds Global configuration If the action option is set to shutdown, the port will enter shutdown mode (i.e. the port is blocked) when the threshold is exceeded. If the traffic rate has been higher than the threshold for a configurable period (countdown timer), the port will enter into shutdown forever mode (i.e. the port is disabled and the status is link-down). When a port is in "shutdown mode", before the port enters into shutdown forever mode it can recover and the port will exit the shutdown mode. if the receiving rate is higher than the falling threshold (80% of the threshold), and lower than the threshold, the port will exit the shutdown mode after a period of time and the timer will then be half of the countdown timer. Furthermore, if the receiving rate is lower than the falling threshold the port will be recovered immediately. If the auto_recover_time value is non-zero, the port will be automatically recovered to the normal situation after the recovery time. Otherwise, the port will CLI Reference Guide 864
