5.11 DHCP Server
DHCP is the abbreviation of Dynamic Host Configuration Protocol that is a protocol for
assigning dynamic IP addresses to devices on a network. With dynamic addressing, a
device can have a different IP address every time it connects to the network. In some
systems, the device's IP address can even change while it is still connected. DHCP also
supports a mix of static and dynamic IP addresses. Dynamic addressing simplifies
network administration because the software keeps track of IP addresses rather than
requiring an administrator to manage the task. This means that a new computer can be
added to a network without the hassle of manually assigning it a unique IP address.
The system provides the DHCP server function. Having enabled the DHCP server
function, the switch system will be configured as a DHCP server.
6.6.1 DHCP Server - Server configuration

DHCP Server: Enable or Disable the DHCP Server function. Enable
—the switch

Start IP Address: Type in an IP address. Low IP address is the beginning of the
dynamic IP range. For example, dynamic IP is in the range between 192.168.16.100
~ 192.168.16.200. In contrast, 192.168.16.100 is the Low IP address.

End IP Address: Type in an IP address. High IP address is the end of the dynamic
IP range. For example, dynamic IP is in the range between 192.168.16.100 ~
192.168.16.200. In contrast, 192.168.16.200 is the High IP address.

Subnet Mask: Type in the subnet mask of the IP configuration.

Gateway: Type in the IP address of the gateway in your network.

DNS: Type in the Domain Name Server IP Address in your network.

Lease Time (Hour): It is the time period that system will reset the dynamic IP
assignment to ensure the dynamic IP will not been occupied for a long time or the
server doesn
’t know that the dynamic IP is idle.
