Note:
For error-free operation at high modulation profiles, no interference should be
present. Switch off or mute remote system before applying the RF loopback.
Alternatively, change remote frequency to eliminate risk of interference.
It will take the system to stabilize after loopback about 3 minutes before checking
radio performance using the alarms and statistics.
Enable the loopback and set the loopback-timeout in seconds (up to 24 hours, 0= no
timeout, recommended minimum of 600 seconds).
RF loopback can be set in the Maintenance section of the Radio page.
Figure 10-3 RF Loopback
This section allows configuring the following parameters:

clearing the loopback in seconds and select the modulation the ODU will be
tested at.

Line loopback timeout
set eth eth1 loopback-timeout 600
RF loopback timeout

Note:
Loopback is performed with MAC addresses swap (swapping DA and SA) for the
address specified only. All other MAC addresses not looped.
