VersaLink™ Gateway (Model 327W)
User Guide
Secondary FW
Secondary firmware version number. This is the station firmware that the
card would use to operate as a wireless station. The format of the number is
…>. The version number is needed to identify existing errata.
OUT and IN
Data preceded by
OUT
pertain to transmissions from VersaLink to a station;
VersaLink is the source.
Data preceded by
IN
pertain to data received by
VersaLink; VersaLink is the destination
.
OUT-Unicast Frames
The number of successfully transmitted frames whose destination address
was a single station, not necessarily the same station, but to any single
station: As opposed to a transmission that multiple stations would receive
(an example would be a broadcast message).
OUT-Multicast Frames
The number of successfully transmitted frames whose destination address
was a multicast address (received by more that one station): not necessarily
broadcast to all stations, but more than a single station. Broadcast messages
are included in the count.
OUT-Fragments
The number of successful transmissions made. This will typically be greater
than the sum of the Unicast and Multicast frames because large frames are
broken into multiple transmissions. The number of fragments per frame is
based on the Fragmentation Threshold setting (not user-configurable).
OUT-Unicast Bytes
The number of bytes transmitted in Unicast Frames. This includes the header
and body of each frame.
OUT-Multicast Bytes
The number of bytes transmitted in Multicast Frames. This includes the
header and body of each frame or frame fragment.
OUT-Transmission Deferred
The number of frames (frame fragments) for which one or more transmission
attempts were deferred to avoid a collision.
OUT-Frames after single retry
The number of frames that were successfully transmitted after one, and only
one, retry. All fragments of the frame must have met this requirement if the
frame was fragmented.
Wireless Statistics Cont.
OUT-Frames after many retries
The number of frames that successfully transmitted after more than one
retry. Any fragment of a frame that required multiple retries would
increment this counter for the whole frame.
OUT-Dropped Frames, too many
retries
The number of frames that did not transmit due to the short or long retry
limit being reached. This number is a result of no acknowledgement or CTS
received.
OUT-Discarded Frames
The number of transmit requests that were discarded to free up buffer space.
This count is incremented when one of the following occurs: 1) A transmit
request is queued too long on the transmit queue due to excessive retries,
deferrals, scans, etc.
2) A transmit request is queued too long on the Power-Save queue because
the station did not poll or wake up in time.
IN-Unicast Frames
The number of successfully received frames whose destination address was a
single location, not necessarily the same location, but to any single location
(as opposed to the broadcast address).
IN-Multicast Frames
The number of successfully received frames whose destination address was a
multicast address. Broadcast messages are included in this count.
IN-Fragments
The number of fragments successfully received. This might not be equal to
the sum of the Unicast and Multicast frames because large frames are broken
into multiple transmissions. The number of fragments per frame is based on
the Fragmentation Threshold setting (not user-configurable) on the source
station.
IN-Unicast Bytes
The number of bytes received in Unicast Frames. This includes the header
and body of each frame or frame fragment.
IN-Multicast Bytes
The number of bytes received in Multicast Frames. This includes the header
and body of each frame of frame fragment.
