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 tunneling
function is selected.
The layer 2 tunneling 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.
For further information, refer to Section 5.4.6.
MAC Mode
IP frames in the direction from the client to the access point always have the MAC
address of the WLAN interface as the source MAC address. As a result, the ARP
tables at the access point end always contain only the MAC address of the WLAN
interface of the clients.
If there are further devices downstream from the client, the Auto Find 'Adopt MAC'
option should not be enabled. In this case, the MAC address would be assigned
indiscriminately to the first device that signals over Ethernet.
If there is only IP communication between the access point and the client, the
default setting AdoptOwnMAC can be retained. If MAC address-based frames also
need to be sent by devices downstream from the client, you will need to select the
settings Adopt MAC manually, Autofind Adopt MAC or layer 2 tunneling.
For further information, refer to Section 5.4.6.
