A management address clearly identifies a device, facilitating network management and the formation of the network topology. The management address is encapsulated in the Management Address TLV of the LLDP packet and then advertised.
The management address must be a legal unicast IP address of the device. If an invalid, the FW automatically finds an IP address and uses it as the LLDP management address. The finding order is: the smallest IP address of loopback interfaces, the smallest IP address of VLANIF interfaces, the smallest IP address of physical interfaces. If no IP address is found, the MAC address of the GE 0/0/0 is used as the management address.
