An advanced Bridge setup parameter for Radio Link Module that
identifies the maximum age of received Spanning Tree protocol
information.
When the bridge receives protocol information that exceeds the Max
Age value, the bridge will discard the information and start the
Forward Delay timer to allow other bridges to forward updated
topology information, e.g. that another bridge has become the Root
Bridge.
Recommended value: 20 seconds.

Messages transmitted by a single station (typically a server) to
multiple stations on the network. This type of traffic is also referred to
as Non-Unicast messages.

In network environments that include several RLMs, the Multicast
Mechanism avoids frame collisions when several access points try to
access the wireless medium at the same time, for example in case of
messages that are transmitted from one station to multiple stations
(Multicast) or all stations (Broadcast) on the network.
The default Multicast Mechanism generates a random delay for each
wireless interface of a Radio Link Module. The random delay is based
