3.3 Ltest (Radio Link Test)
Test of a radio link. It is recommended for antenna alignment when installing a
new device or for testing of existing radio link.
Syntax:
ltest IFNAME target [-r rate[,reply_rate]] [-s
packet_size[,reply_size]] [-b] [-p priority] [-align
[L[,R]]] [-evm][-tb [seconds]] [-tu [seconds]] [-load
N[m|k] [-mint]ltest -key [PASSWORD]
ltest (-disable|-enable)
Description:
 IFNAME - radio interface on which testing will be performed
 target - MAC-address of a target device on the other side of a tested radio link
 -r rate[,reply_rate] - sets bitrates for transmitting test packets from the local
device and toward it. This parameter is optional. There are two situations
when this parameters are not configured:
» Local device is tested with its neighboring node, i.e. we can view remote
device and tx/rx bitrate values for it in a "mint map" command output. In
this case tx/rx bitrate values from "mint map" command output are
taken for rate and reply rate parameters.
» Local device doesn't consider remote device as a neighboring node. In this
case rate and reply rate parameters will be equal to minimal possible
bitrate of the local device for current bandwidth (for example, 13 Mbps for
20 MHz bandwidth, 6.5Mbps for 10 MHz, 3.25 Mbps for 5 MHz).
 -s packet_size[,reply_size] - establishes test packet payload size from the
local device and toward it.
 -b - transmitting broadcast test packets
NOTE
It is possible to set all the bitrates supported by the given device model. Even ones that are not
allowed by the current license. This allows estimating the performance of the device before
upgrading to the higher bitrate.
