It is possible to configure a DHCP server on the Ethernet 2 network of the TM251MESE.
The DHCP server offers addresses to the devices connected on the Ethernet 2 network. The DHCP server only delivers static addresses. A unique identified slave gets a unique address. DHCP slave devices are identified either by their MAC address or their DHCP device name. The DHCP server configuration table defines the relation between addresses and identified slave devices.
The DHCP server addresses are given with an infinite lease time. There is no need for the slave devices to refresh the leased IP address.
For more information, refer to IP Addressing Methods.
