Max Age
An advanced Bridge setup parameter for Base Station 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.
Multicast
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.
Multicast Mechanism
In network environments that include several Base Stations, 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 Base Station. The random delay is based on the last digits of the MAC
address of the inserted BreezeNET PC Card.
Optionally you can define a ‘User-defined’ Multicast delay in the range of 1-10.

N
Noise Level
The Noise level is the level of local background noise as measured at the wireless
interface of a Base Station. The Noise level counter reflects only the Noise Level
value (in %) of the latest frame that was received on the interface.

Non-Unicast packets in
The number of Non-Unicast packets delivered to a higher protocol, typically
Multicast or Broadcast messages.
See also: AP Manager Remote Statistics
Non-Unicast packets out
The number of packets requested by higher level protocols, to be transmitted to a
subnetwork-unicast address, typically Multicast or Broadcast messages. This
number includes the frames that were discarded or not sent.

O
Out Collisions
The number of successfully transmitted frames on a particular interface for which
transmission is inhibited by exactly one or more collisions plus the number of
