6.6 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.

6.6.1System configuration

•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.

• And then, click Apply
