Configuring the Access Point to Provide DHCP Service
The following sections describe how to configure the wireless device to act as a DHCP server:
• Setting up the DHCP Server, page 332
• Monitoring and Maintaining the DHCP Server Access Point, page 334
Setting up the DHCP Server
By default, access points are configured to receive IP settings from a DHCP server on your network. You
can also configure an access point to act as a DHCP server to assign IP settings to devices on both wired
and wireless LANs.
Note When you configure the access point as a DHCP server, it assigns IP addresses to devices on its subnet.
The devices communicate with other devices on the subnet but not beyond it. If data needs to be passed
beyond the subnet, you must assign a default router. The IP address of the default router should be on
the same subnet as the access point configured as the DHCP server.
For detailed information on DHCP-related commands and options, see the DHCP part in Cisco IOS IP
