   Note the following status fields:

   • Occurrences: Displays the current number of threshold-breaching events

   • Current Mode: Displays the current mode of the device. Normal means that layer 2 pass-through mode is not enabled in the device. L2 Pass-Through Mode means pass-through mode is enabled.
