Parameters
shutdown: Enables the shutdown mode. If a loop is detected, the device generates a log and shuts down
the port.
Usage guidelines
Use this command to configure the loop protection action globally.
To configure the loop protection action on a specific port, use the loopback-detection action command
in interface view.
The global configuration applies to all ports. The per-port configuration applies to the individual ports.
The per-port configuration takes precedence over the global configuration.
