3-40 General Functions of the Configurator
1 The client asks DHCP server for IP address and configuration if needed.
Note: The DHCP server allows IP addresses be assigned dynamically at the remote
building. Distributing these administrative functions to each remote building
significantly reduces the "administrative overhead" traffic that must travel back to the
service provider's headquarters. A DHCP server is configured with a table of IP
addresses that are assigned to client network devices asking for network settings. The
DHCP server uses a "lease" to determine the length of time that a device or interface
can use the assigned IP address.
2 The DHCP server assigns an available IP address to the client.
3 The client takes the IP address from DHCP server and requests for additional
configuration that is needed.
4 DHCP server confirms IP address and configuration.
The SPEEDLAN 9000 Configurator allows you to assign IP addresses via DHCP on the
interfaces.
Basic Instructions for Setting Up DHCP on an Interface
Important Notes:
• The DHCP server and DHCP client are only available for Ethernet (wired)
interfaces.
• The DHCP server can only be configured to serve IP addresses on the
subnet where its Ethernet IP address resides.
1 Choose DHCP Server from the main menu. Then, choose the appropriate
interface where you want to offer DHCP.
2 This will bring up the DHCP page. Choose General Clients to assign an IP to
your DHCP clients. When you define the scope of IP addresses to be assigned,
make sure you do not include any of the static IPs that you have assigned on
the network. (For definitions, see General DHCP Elements Defined,
page 3-44.)
