Support dual-system hot backup for authentication. That is, when the host is working normally, it forwards and responds to the upstream and downstream ip data packets of the switch, and the standby machine only performs heartbeat detection and user data and user online status synchronization with the host through the custom Ethernet packet. The standby machine does not respond to the received IP data packets. Respond and forward. The heartbeat detection interval is 10-20 seconds. When the standby machine does not receive the heartbeat detection packet from the host within the heartbeat interval, the standby machine automatically starts responding and forwarding IP packets to complete the switch.
