IP-Link definition on the USG
IP-Link indicates the link accessibility check. The firewall periodically sends ICMP echo requests or ARP requests to the specified destination IP address and waits for responses. If no response is received with the specified period of time, the firewall considers that the current link is faulty and performs subsequent link-related operations. If the firewall receives three consecutive responses over the original link within the subsequently-specified period of time, the firewall considers that the link fault is eliminated and performs subsequent link recovery-related operations.

IP-Link purposes on the USG
IP-Link is mainly used to automatically detect whether a service link is normal. It can be used to detect the status of a link that is not directly connected to the firewall to ensure service continuity.
