● be established with a maximum of eight components if the layer 2 tunneling function is
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.
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 frames based on MAC addresses are also sent by
devices downstream from the client, you will need to make the Adopt MAC settings
manually.
Select Autofind Adopt MAC or layer 2 tunneling.
MAC address/IP address assignment
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. In principle, any number of device is can be reached
downstream from a client using IP. The client can manage up to eight devices. When a new
device is added, the oldest entry is deleted from the table to make space is for the new entry.
Since the data throughput of a wireless connection cannot be increased indefinitely, a
maximum of the devices should be managed by one client.
