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 9200 Configurator allows you to assign IP addresses via DHCP on the
interfaces.
Setting Up DHCP and DHCP Relay
These instructions will explain how to:
• Configure and Manage the SPEEDLAN 9200 DHCP Server
• Configure DHCP Relay
Important Note about DHCP
The DHCP Server serves IP addresses via the wireless interfaces in addition to the
Ethernet interface. The DHCP Server does not serve other nodes on the same wireless
cell.
For example, for Node A's DHCP server to serve IP addresses via its wireless interface,
at least one of the following must be true:
• Another SPEEDLAN 9200 router on the same cell has DHCP Relay enabled,
and configured to use Node A's DHCP server.
• Beyond the Ethernet of a SPEEDLAN 9200 router on the same cell, there is a
router (wired or wireless) whose DHCP Relay is enabled and configured to use
Node A's DHCP server.
