DHCP (Dynamic Host Configuration Protocol) allows individual clients to obtain TCP/IP configuration
at start-up from a server.
DHCPv4 Server: If set to Enabled, your BEC 4700A/AZ can assign IP addresses, default gateway
and DNS servers to the DHCP client.
 If set to Disabled, the DHCP server will be disabled.

and responses between the remote server and the clients. Enter the IP address of the actual,
remote DHCP server in the Remote DHCP Server field in this case.
