IP mapping table

WLAN access for several SCALANCE W700 devices via a client
Note
This WBM page is only available for clients or access points in client mode.
You can make WLAN access available for several SCALANCE W700 devices with one client
if you use IP mapping. This means that you do not need to equip every SCALANCE W700
device with its own WLAN client. This is possible only if the connected SCALANCE W700
devices are addressed only by IP frames. Communication at MAC address level (ISO/OSI
layer 2) can
● be established with one component whose MAC address is configured on the client,
● be established with a maximum of eight components if the "Layer 2 Tunnel" function is
selected.
The "Layer 2 Tunnel" setting meets the requirements of industrial applications in which MAC
address-based communication takes place with several SCALANCE W700 devices
downstream from the client. Clients with this setting cannot connect on standard Wifi access
points.
The client maintains a table with the assignment of MAC address and IP address to send
incoming IP frames to the correct MAC address. This WBM page shows this table.
Note
IP mapping table
If "Layer 2 Tunnel" is configured for a client, the IP mapping table is not displayed.
