About DHCP (server address setting function) of logical network.

DHCP (address setting function) of the logical network is a function to set the address to the server menu (bare metal / virtual server). Unlike general DHCP, because it is a mechanism to pass address information as an indefinite lease based on information on port and subnet, we will set the same IP address every time. Even when this function is activated, it is possible to assign an arbitrary IP address permanently. Please specify an arbitrary address by the address assigning function on the port. When this function is enabled, one IP address for setting logical port (DHCP server port) is required. Automatically assign the lowest number of unused addresses in the IP address allocation pool.
