Description
This parameter defines the traffic forwarding method:
L2 Switching mode: traffic flooding is enabled.
To dynamically learn about station locations, the Base Station listens to incoming
frames and keeps a table of address information by inspecting the source MAC
addresses. If the source MAC address is not in the address table already, it is
recorded in the table.
As a part of the forwarding decision, if destination MAC address is found, the
frame can be forwarded to that address. If the address is not found in the table,
the frame is flooded to all the CPEs (if it's a downlink packet) and to the CPEs
and network interface (if it's an uplink packet).
Forward-to-router mode (To be used for testing purposes only!!!): all traffic is
forwarded to the upstream router (no flooding). Do NOT use it.
Values: [L2 Switching; Forward-to-router]
Mac Address Table Aging period (in seconds), after which unused MAC address
entries will be dropped.
Values: 300-1800
