Setting the loop detection interval
With loop detection enabled, the device 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:
