The following commands initiate an IF loopback on radio interface 2, with a timeout of two minutes:
radio[2/1]> radio loopbacks-timeout set duration 2
radio[2/1]>rf loopback-rf set admin on
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
