IP Mapping Table
WLAN access for several devices via a client
Note
This page is only available for clients or access points in client mode.
You can make WLAN access available for several devices with one client if you use IP
mapping. This means that you do not need to equip every device with its own WLAN client.
This is possible only if the connected 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 devices downstream from the client.
Clients with this setting cannot connect to standard Wi-Fi devices and access points with
firmware V3.0 or older.
The client maintains a table with the assignment of MAC address and IP address to be able
to send incoming IP frames to the correct MAC address. The "IP Mapping Table" menu
command displays this table.
Note
IP mapping table
If "Layer 2
Tunnel" is configured for a client, the IP mapping table is not displayed.
