management address of the device:
- Auto Advertise—Specifies that the software automatically chooses a management 
address to advertise from all the IP addresses of the device. In case of multiple IP

addresses. If there are no dynamic addresses, the software chooses the lowest IP 
address among the static IP addresses.
