The management address of a device is carried in the Management Address TLV field of the LLDP packet. The NMS uses management addresses to identify and manage devices.
If no management address is configured or an invalid management address is configured, the system sets an IP address in the address list as the management address. The system selects the IP address in the following sequence: iMaster NCE-Campus's IP address, loopback interface address, management port address, VLANIF interface address, VBDIF interface address, Layer 3 Ethernet interface address, and Sub-interface. Among the IP addresses of the same type, the system selects the smallest one. If the system fails to find a management IP address, the bridge MAC address is used as the management address.
