T
TTL (Time-To-Live)
An advanced IP Parameter Setup counter that you can you use to maintain network
efficiency. The purpose of the Time To Live counter (TTL) is to avoid endless
forwarding of message frames with an incorrect address that pollute the network
medium.
The TTL defines a maximum number of passes per hop. Each time the frame is
forwarded by a router, the TTL counter decreases by one. When the TTL = 0, the
frame is rejected.
U
Unicast packets in
The number of subnetwork-frames delivered to a higher protocol. This is ‘true data’
from station to station.
Unicast packets out
The number of bytes (octets) transmitted out to the interface.
This is ‘true data’ from station to station.
Up Time
The amount of time elapsed since the last time the Base Station unit was powered

W
Windows workgroup
A Windows workgroup can consist of either wireless or wired network connections
or a combination of the two. Usually a Windows workgroup consists of members
who are related because of a shared function, e.g. members of the same
department. For a Windows workgroup it is not relevant where the workgroup
participants are located, since the members of a Windows workgroup are identified
by their workgroup name only.
