xStack® DGS-3200 Series Layer 2 Gigabit Ethernet Managed Switch and is no longer operational until the user manually resets the port using the Port Settings window (Configuration > Port Configuration> Port Settings). Choosing this option obligates the user to configure the Time Interval setting as well, which will provide packet count samplings from the Switch's chip to determine if a Packet Storm is occurring. Count Down (0 or 5-30) The Count Down timer is set to determine the amount of time, in minutes, that the Switch will wait before shutting down the port that is experiencing a traffic storm. This parameter is only useful for ports configured as Shutdown in their Action field and therefore will not operate for hardware-based Traffic Control implementations. The possible time settings for this field are 0 and 5 to 30 minutes. Time Interval (5-30) The Time Interval will set the time between Multicast and Broadcast packet counts sent from the Switch's chip to the Traffic Control function. These packet counts are the determining factor in deciding when incoming packets exceed the Threshold value. The Time Interval may be set between 5 and 30 seconds, with a default setting of 5 seconds. Threshold (512- Specifies the maximum number of packets per second that will trigger the Traffic Control function to 1024000) commence. The configurable threshold range is from 512 to 1024000, with a default setting of 512 Kbps. Storm Control Type Specifies the desired Storm Control Type: None, Broadcast, Multicast, Unknown Unicast, Broadcast + Multicast, Broadcast + Unknown Unicast, Multicast + Unknown Unicast, and Broadcast + Multicast + Unknown Unicast. Traffic Trap Settings Enable sending of Storm Trap messages when the type of action taken by the Traffic Control function in handling a Traffic Storm is one of the following: • None - Will send no Storm trap warning messages regardless of action taken by the Traffic Control mechanism. • Storm Occurred - Will send Storm Trap warning messages upon the occurrence of a Traffic Storm only. • Storm Cleared - Will send Storm Trap messages when a Traffic Storm has been cleared by the Switch only. • Both - Will send Storm Trap messages when a Traffic Storm has been both detected and cleared by the Switch. This function cannot be implemented in the hardware mode. (When Drop is chosen for the Action parameter. Click Apply to implement the settings of each field. NOTE: Traffic Control cannot be implemented on ports that are set for Link Aggregation (Port Trunking). NOTE: Ports that are in the Shutdown Forever mode will be seen as Discarding in Spanning Tree windows and implementations though these ports will still be forwarding BPDUs to the Switch's CPU. NOTE: Ports that are in Shutdown Forever mode will be seen as link down in all windows and screens until the user recovers these ports. 93
