Configuring the loop protection action
You can configure the loop protection action globally or on a per-port basis. 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.

log but performs no action on the
port on which a loop is detected.

Setting the loop detection interval
With loop detection enabled, the switch sends loop detection frames at a specified 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:
