Whether loop detection can be configured on the firewall interface

The USG2000&5000&6000 do not support configuring the loop detection command at the interface. Loop detection usually applies to detection at the lower-layer switches.
On the firewall:
1. You can make a comparison by viewing interface traffic information. If the traffic volumes of certain interfaces are large and similar, a loop may occur.
2. If a loop occurs, the following alarm information is displayed.
Alarm information: PPP/4/TRAP: [oid] Interface (IfIndex:[interface-index]) LoopBack is detected
