3.4.10 Antenna Tracking / Rate Monitoring
NOTE: A Mainte-
nance user can run
the show tracking com-
mand in continuous
mode (-samples 0) while
an Administrative user
adjusts the radio and
bss configuration for
best link quality.
Administrative and Maintenance users have the ability to
monitor the data rate and RSSI of a specific WDS link between
two Fortress Mesh Points using the
show command:
# show tracking -mac <macAddr> -radio <RadioName> -interval <Interval>
-samples <Samples> -format <Format>
macAddr is the MAC address of the specific radio of the
Fortress Mesh Point to which this FMP is connected. An FMP
has a base MAC address, but it also has individual MAC
addresses for each radio. To figure out which address to use,
run the
show bss command on the remote FMP. Use the
BssId MAC address of the appropriate BSS on the remote
FMP as the macAddr in the command on this FMP.
CAUTION: The
show tracking
command may have an
impact on the perfor-
mance of the FMP and
the throughput of data
on the channel.
RadioName
is the name of the radio on this FMP that connects
to the remote FMP. The default radio name is radio2.
Interval is the time in milliseconds between lines of
monitoring output. The default interval is 100 milliseconds, or
10 output lines per second.
Samples is the number of output lines to emit. The default
number of samples is 50 lines. If you enter 0, the output lines
will continue to show until you hit Ctrl-C to stop the output.
CAUTION: The
show tracking
command should never
be run by more than one
user simultaneously.
Format
is the format of the output. The default (and only
current capability) is format 1, which is:
$BATSR,RADIO_NAME,VERSION,MODE,LINK_STATUS,RSSI,LINK_SPEED,LINK_DISTA
NCE,REMOTE_IP,REMOTE_MAC,*CHECKSUM
# show tracking -mac 00:14:8c:00:0a:b4
$BATSR,ES-00148cf80780radio2,5.4.5.2041-CS,WDS,Connected,-41,54,N/
A,N/A,00:14:8c:00:0a:b4,*7e
In this example, BATSR is a hardcoded string that refers to this
format. WDS is the mode. LINK_DISTANCE and REMOTE_IP
are unavailable, so they are shown as N/A. 00:14:8c:00:0a:b4
is the MAC address of the remote FMP. It will always be the
same MAC that was requested in the show command. Finally
the *7e is the NMEA-0183-compliant XOR data sum prefixed
by '*'.
This command is useful when trying to aim the FMP's antenna
in a new installation, and also when trying to debug link quality
issues. For best results, the LINK_SPEED value should be as
high as possible. The RSSI should be the smallest absolute
number (e.g. -47 is much better than -85), but not past -35 for
ES820s and ES2440s, and not past -25 for ES520s.
