Setting the loop protection action
You can set the loop protection action globally or on a per-port basis. The global setting applies to all
ports. The per-port setting applies to the individual ports. The per-port setting takes precedence over
the global setting.

By default, the device generates a
log but performs no action on the
port on which a loop is detected.

By default, the device
generates a log but performs
no action on the port on which
a loop is detected.
Setting the loop detection interval
With loop detection enabled, the device sends loop detection frames at the loopback detection
interval. A shorter interval offers more sensitive detection but consumes more resources. Consider
the system performance and loop detection speed when you set the loop detection interval.
To set the loop detection interval:
