Introduction to the Auto Detect Function

The Auto Detect function uses ICMP request/reply packets to test network connectivity regularly.

The detected object of the Auto Detect function is a detected group, which is a set of IP addresses. To check the reachability to a detected group, a device enabled with Auto Detect sends ICMP requests to the group and waits for the ICMP replies from the group based on the user-defined policy (which includes the number of ICMP requests and the timeout waiting for a reply). Then according to the check result, the device determines whether to make the applications using the detected group take effect.

Currently, the following features are used in conjunction with Auto Detect:
