Command config traffic control Parameters [<storm_grouplist> | all] {broadcast [enable | disable] | multicast [enable | disable] | dlf [enable | disable] | threshold <value 641024000>} {group_list <storm_grouplist>} show traffic control Each command is listed, in detail, in the following sections. config traffic control Purpose Syntax Used to configure broadcast / multicast traffic control. config traffic control [<storm_grouplist> | all] {broadcast [enabled | disabled] | multicast [enabled| disabled] | dlf [enabled | disabled] | threshold <value 64-1024000>} This command is used to configure broadcast storm control. <storm_grouplist> - Used to specify a broadcast storm control group. broadcast [enabled | disabled] - Enables or disables broadcast storm control. multicast [enabled | disabled] - Enables or disables multicast storm control. threshold <value 64-1024000> - The upper threshold at which the specified traffic control is switched on. The value is the amount of broadcast/multicast/dlf traffic, in Kbps, received by the Switch that will trigger the storm traffic control measures. Restrictions Example usage: To configure traffic control and enable broadcast storm control system wide: DES-3026:4# config traffic control all broadcast enabled Command: config traffic control all broadcast enabled Success. DES-3026:4# Only administrator-level users can issue this command.

[. . . ] candidate ­ Used to change the role of a commander switch to a candidate switch. dp_interval <30-90> ­ The user may set the discovery protocol interval, in seconds that the Switch will send out discovery packets. Returning information to the commander switch will include information about other switches connected to it. The user may set the discovery protocol interval from 30 to 90 seconds. [. . . ]
