Basic Information on Wireless LAN Communication

C79000-G8976-C184-07

Communication at the MAC address level (ISO/OSI layer 2) is then only possible

with a component downstream from the client if its MAC address was adopted by

the client.

client: 0

Layer 2 Tunneling (only W746/W747 and W788 in client mode)

With layer 2 tunneling, the client provides information about the devices

downstream from it when it registers with an access point. This makes it possible to

enter the MAC addresses of these devices in the learning table of the access point.

The access point can forward MAC-based frames for the devices downstream from

priate client.
