Hardware restrictions of hot standby on the USG2000 and USG5000 series

Hardware restrictions of hot standby: 1. Currently, hot standby can be implemented only between two devices. 2. The active and standby devices must have the same product model and version. 3. The active and standby devices must have the same number and types of boards installed in the same arrangement. Otherwise, the information synchronized from the active device does not match the physical configuration of the standby device. As a result, faults occur after an active/standby switchover. 4. If you want to use a Layer 2 interface as the heartbeat interface, you need to add it to the VLAN, create the VLANIF interface, and configure the IP address of the VLANIF interface. Then use the VLANIF interface as the heartbeat interface and specify the heartbeat interface IP address of the peer device.
