Parameters
shutdown
: Enables the shutdown mode. If a loop is detected, the device generates a log and shuts
down the port. The device automatically brings up the port after the detection timer expires. You can
use the
shutdown-interval
command to set the detection timer. For more information, see
Fundamentals Command Reference
.
Usage guidelines
To configure the loop protection action on a per-port basis, 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.
Example
# Set the global loop protection action to
shutdown
.
