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.
6.6.1 System 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.
