Link Management Commands
Once the radios are properly aligned for maximum RSSI, ensure the SU’s default Opmode is “ON” and that all
configuration parameters are correct.
Reboot the SU. Once the SU enters Opmode “ON” the authentication process will begin, and the two radios
will begin to associate. From the AP side, there are several basic diagnostics commands such as su ping, su
info, and su testrflink to ensure that a reliable RF link has been established. It may take one minute or more
for the association process to complete. This process may take longer if there are many SUs in the sector.
If all tests show favorable results, the wireless link will automatically begin passing Ethernet traffic
between the radios.
In establishing and diagnosing the quality of the link between AP and SU(s), there are a few commands that
are especially useful. All of these commands are performed at the AP. A summary of these commands
follows:
su
Displays the status of all SUs in the APs database. SUs in the SU database will appear by SU ID, classified
into one of the following status categories: Associated, Associating, or OFF. All associated SUs will be
indicated
Example:
#> su
[Priority] 1
[0] 1
[1]
[2]
[3]
[4]
[5]
[Associating]
[Power Off] 17
Success.
su ping <su#>
AP will send 10 RF pings to the designated SU ID. The response from each ping will indicate latency (in
micro-seconds) and the received signal strength (RSSI) from the SU for each of the 10 pings. Note this
command will also tell you the distance from the AP to the SU.
Example:
#> su ping 1
[#Begin]
[001]
Ping #0 -> -52 dB 220 us 0.0 mi
Ping #1 -> -53 dB 219 us 0.0 mi
Ping #2 -> -53 dB 220 us 0.0 mi
Ping #3 -> -52 dB 220 us 0.0 mi
Ping #4 -> -53 dB 219 us 0.0 mi
Ping #5 -> -52 dB 220 us 0.0 mi
Ping #6 -> -50 dB 220 us 0.0 mi
Ping #7 -> -52 dB 220 us 0.0 mi
Ping #8 -> -52 dB 220 us 0.0 mi
Ping #9 -> -52 dB 220 us 0.0 mi
