Configuring physical port loopbacks

You can use the CLI to loop a physical port back on itself, either locally or remotely:

• The local loopback is a physical-layer loopback. If the hardware does not support a physical-layer loopback, a MAC-address loopback is used instead.
• The remote loopback is a physical-layer lineside loopback.

By default this feature is disabled.

To configure a physical port loopback:

config switch physical-port

edit <port_name>

set loopback {disable | local | remote}

next

end
