Chapter 3 - Layer 2 Command Set - PHY and MAC Ltest (Radio Link Test)
Alvarion BreezeNET B130/B300 GigE 62 Operational User Manual
-p - sets priority level to "ltest" packets (from 0 to 16). No priority is set by
default.
-key [PASSWORD] - sets password for testing. If two devices have different
passwords they can't perform testing with each other
-disable|-enable - disables/enables ability to perform link test. Enable by
default
-align [L[,R]] - special "ltest" command mode for antenna alignment. It allows
aligning each antenna of the device independently. L parameter sets which
antenna will be used to transmit test frames from the local device. R
parameter sets which antenna will be used to transmit test frames from the
remote device from the other side of the link. If L parameter is not specified
then average signal level value between two antennas will be shown. If -r is not
specified then test can be performed even when only one antenna is attached
to each side of the link. If -r is specified then L and R parameters are ignored.
L and R parameters can have the following values: 0 - antenna with vertical
polarization, 1 - antenna with horizontal polarization.
-evm - indicates the measured input signal quality (Error Vector Magnitude).
It should be as high as possible. The recommended level is not less than 21.
All parameters (including specified by default) keep its values the same as they
were at the beginning during the whole test.
Examples:
lt rf5.0 00179AC2F3E6
This command illustrates the simplest way to start link test. "lt" command with
all parameters undefined (default parameters) starts test of a local device with a
remote device which have "00179AC2F3E6" MAC-address.
lt rf5.0 00179AC2F3E6 -r 39000
This command starts link test with rate parameter 39 Mbps. In this case reply
rate parameter will be considered the same.
"ltest" command recommendations:
When "ltest" command starts it will show you output information that contains
testing results. You can see command output below:
