Step 1

the CLI, web-browser interface, or Cisco Prime Infrastructure procedures as described in the
appropriate Cisco wireless LAN controller guide.
a. Make sure that access points have Layer 3 connectivity to the Cisco wireless LAN controller
Management and AP-Manager Interface.
b. Configure the switch to which your access point is to attach. See the Cisco Wireless LAN
Controller Configuration Guide for the release you are using, for additional information.
c. Set the Cisco wireless LAN controller as the master so that new access points always join with
it.
d. Make sure DHCP is enabled on the network. The access point must receive its IP address
through DHCP.
e. CAPWAP UDP ports must not be blocked in the network.
f. The access point must be able to find the IP address of the controller. This can be
accomplished using DHCP, DNS, or IP subnet broadcast. This guide describes the DHCP
method to convey the controller IP address. For other methods, refer to the product
documentation. See also the
