Performing Ethernet Loopback
Ethernet loopbacks can be performed on any logical Ethernet interface except a LAG. When Ethernet loopback is
enabled on an interface, the system loops back all packets ingressing the interface. This enables loopbacks to be
performed over the link from other points in the network.
To perform Ethernet loopback:
1. Select Ethernet > Interfaces > Logical Interfaces. The Logical Interfaces page opens
2. Select an interface in the Ethernet Logical Port Configuration table and click Loopback. The Logical Interfaces –
Loopback page opens.
