Configuring the

Access Point as a

DHCP Server

Parameter	Explanation
DHCP for Access	Determines which DHCP servers may be used by
Point Network	access points and wireless devices:
	Use Any Available DHCP Server: Access points
	and wireless devices may receive DHCP
	responses and addresses from any available
	DHCP server.
	Only Use Access Point DHCP Server: Access
	points and any associated wireless devices may
	receive DHCP responses and addresses only
	from an access point DHCP server. Currently, the
	DHCP server must be located in the root access
	point. If this option is selected and the root
	access point does not have a DHCP server
	enabled, access points and wireless devices will
	not be able to receive a DHCP address. You can
	use this option, in combination with a DHCP user
	class, to segment a network that has an existing
	DHCP server and an access point DHCP server.

You can configure the access point as a simple DHCP server that provides DHCP server functions for small installations where no other DHCP server is available. The DHCP server will offer IP addresses and other TCP/IP settings to any DHCP client it hears as long as a pool of unallocated IP addresses is available. These clients may include other access points, wireless end devices, wired hosts on the distribution LAN, or wired hosts on secondary LANs.

Note

If you configure the access point as a DHCP server, it is not intended to replace a general purpose, configurable DHCP server, and it makes no provisions for synchronizing DHCP policy between itself and other DHCP servers. Customers with complex DHCP policy requirements should use other DHCP server software.

Note

You cannot configure the access point as both a DHCP server and a DHCP client.

To avoid a single point of failure, you can configure more than one access point to be a DHCP server; however, the access points do not share DHCP client databases. You should configure each DHCP server with a different address pool from which to allocate client IP addresses.
