Siemens SCALANCE X-300 Configuration Manual page 137

Note
If passive listening is enabled, the IE switch forwards (R/M)STP configuration frames
transparently even when (R/M)STP is disabled for it. If it recognizes a topology change
frame, it reduces the aging time for a limited period so that the node list is updated more
quickly.
Once this period has elapsed, the original aging time applies again.
Enhanced Passive Listening Compatibility
If you enable Enhanced Passive Listening Compatibility, TCN (Topology Change
Notifications) frames will be sent via RSTP edge ports. In conjunction with the "Auto Edge
Port" function (section Spanning Tree Port Parameters (Page 199)), this parameter is
necessary to link (R)STP networks with HRP rings. Otherwise no TCN frames will be sent
via edge ports; this is, however, necessary for the passive listening function on ring nodes
(refer to the operating instructions of the relevant switch).
RSTP Big Network Support
If you enable RSTP Big Network Support, large RSTP rings with up to 80 bridges are
supported.
