DHCP Server—System configuration
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. The system provides the DHCP server function. Having
enabled the DHCP server function, the switch system can be a DHCP server.
•
DHCP Server:
Enable or Disable the DHCP Server function. Enable—the switch will be the DHCP
server on your local network.
•
Low 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 192.168.1.100 ~ 192.168.1.200. In contrast,
192.168.1.100 is the Low IP address.
•
High 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 192.168.1.100 ~ 192.168.1.200. In contrast,
192.168.1.200 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 (sec):
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.

DHCP Client—System Configuration
When the DHCP server function is active, the system will collect the DHCP client information and
displays it here.
