Passive listening
Menu path
You can find this information in the following paths:
•
With MSPS: "Layer 2 > Configuration"
•
With X-200 and X-300: "Switch > Configuration"
Recommendation
"Passive Listening" is disabled by default on most SCALANCE X devices.
If there is no constellation in the network that relies on a coupling from STP to an
HRP ring or MRP ring, for example, then disable "Passive Listening".
Note
"Passive Listening" causes the SCALANCE device to forward BPDUs. An incoming
topology change causes it to delete its MAC address table.
The SCALANCE device deletes the MAC address table even if the device itself has
not enabled STP or does not support STP at all.
