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.

3.
In the
Ethernet loopback admin
field, select
Enable
to enable Ethernet loopback on the logical interface, or
Disable
to disable Ethernet loopback on the logical interface.
4.
In the
Ethernet loopback duration (sec)
field, enter the loopback duration time (in seconds).
5.
In the
Swap MAC address admin
field, select whether to swap DA and SA MAC addresses during the loopback.
Swapping addresses prevents Ethernet loops from occurring. It is recommended to enable MAC address
swapping if LLDP is enabled.
6.
Click
Apply
to initiate the loopback.
