timeout of two minutes:

Performing Ethernet Loopback (CLI)
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 configure loopback on an Ethernet interface, go to interface view for the
interface and enter the following command:
eth type eth[x/x]> loopback admin <loopback-admin-state>
To configure the loopback duration time, go to interface view for the interface
and enter the following command:
eth type eth[x/x]> loopback set duration <loopback-duration>
You can 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.
To configure MAC address swapping, go to interface view for the interface and
enter the following command:
eth type eth[x/x]> loopback swap-mac-address admin <MAC_swap-
admin-state>
To view loopback status, go to interface view for the interface and enter the
following command:
eth type eth[x/x]> loopback status show
