5.4 Loopbacks
The MultiHaul™ radio uses Ethernet and RF loopbacks designed to enable fault isolation
and Ethernet service performance testing.
• Line Loopback – Internal loopback is performed on the interface, looping the
line egress traffic towards the bridge (radio).
• RF (Radio) Loopback – Internal loopback is performed on the bridge’s RF
interface, looping RF egress traffic towards the bridge (line output).
Note:
After activating Loopback, it is important to clear all RF and Ethernet statistics in
order to receive the most accurate results for analysis.
