Passive Listening
This section describes commands of the passive listening function.
If you enable passive listening, the IE switch forwards (R)STP configuration frames (BPDUs)
transparently even when (R)STP is disabled for it. The IE switch also reacts to topology change
frames. When the IE switch receives a TC frame, it deletes the MAC address table.
