Manual Revision: 1.0
Using the Counters windows, you can view a wide range of performance
data at both sides of the link. For RB units, you can monitor the
received signal strength through the RSSI (Received Signal Strength
Indication) bar indicator at the bottom of the window. This RSSI bar can
be used to optimize antenna alignment and improve link quality. The
RSSI bar does not appear for BU units.
Additional performance counters displayed in this window include the
following. To obtain a graph that displays the counter values, select a
counter and drag it to the icon.
! Tx Counters
" Tx Fragments - The number of transmitted frames. The
count includes data, control, management frames and the
number of retransmissions of data frames (for example, if
the same data frame is retransmitted ten times then the
count will increase ten times).
" Tx Frames - The number of frames successfully transmitted
to the wireless media. The count includes the first
transmission of data frames (without retransmissions), and
the number of control and management frames.
" Multicast Tx Frames- The number of successfully
transmitted multicast frames.
" Retry Count - The number of frames that were successfully
transmitted after one of more retransmissions.
" Multiple Retry - This counter is incremented when a packet
is successfully transmitted after more than one
retransmission.
" Failed Count - This counter is incremented when a packet is
not transmitted successfully due to the number of transmit
attempts exceeding either the Short Retry Limit or Long
Retry Limit.
! Rx Counters
" Rx Fragments - The number of frames received, including
data, control, and duplicate data frames.
" Multicast Rx Frames - The number of received multicast
frames.
" FCS Error - The number of frames received with a CRC
error.
" FCS Error (%) - The percentage of frames received with a
CRC error, calculated as follows:
100*FCS Error / (Rx Fragments + Multicast Rx Frames +
FCS Error).
"Frame Duplicate - The number of duplicate frames that were
received.
