Configuring trapd.conf file to manage flooding of traps

In order to avoid the trap receiver and trap exploder from crashing due to flooding of traps, the default values for the QUEUE_LIMIT_MEGS and QUEUE_LIMIT_SECONDS parameters in the trapd.conf file are set to 200 MB and 480 seconds, respectively. On reaching the limits set using these parameters, the sm_trapd queue starts discarding traps. An alert, trapdDiscardingTraps, which is defined in the trap_mgr.conf file is triggered when the queue starts discarding traps. If and when a device is identified as the source of a trap storm, information about it is logged in the sm_trapd log file.

The Service Assurance Manager Adapter Platform User Guide provides details on the parameters in the trapd.conf file.
