Ensuring That APs Can Discover the Controller on the Network

Method 4: Configure DHCP Option 43 on the DHCP Server

Method 4: Configure DHCP Option 43 on the
DHCP Server
Another method for the AP to discover the controller on the network automatically
is to configure the DHCP server on the network. To do this, you will need to configure
DHCP Option 43 (043 Vendor Specific Info) with the IP address of the controller on
the network. When an AP requests an IP address from the DHCP server, the DHCP
server will send a list of controller IP addresses to the AP. If there are multiple
controller devices on the network, the AP will automatically select a controller to
register with from this list of IP addresses.
DHCP Option 43 enables the DHCP server on your network to provide the
controller's server address – either IP address or FQDN– (specifically, the IP address
assigned to the controller's control plane or cluster plane interface) to DHCP clients,
including APs that are connected to the network.
The procedure for configuring DHCP option 43 varies, depending on the DHCP
server that you are using. Refer to the documentation provided with your DHCP
server software for information on how to configure DHCP option 43.
NOTE: The following procedure describes how to configure DHCP option 43 on a
Linux server (Fedora). If your DHCP server is running on a different platform, refer
to the DHCP server documentation for the relevant instructions.
CAUTION! If you have a ZoneDirector controller on the network and you do not
want APs to be managed by this ZoneDirector controller, you must disable auto
approval on the ZoneDirector web interface. Log on to the ZoneDirector web
interface, and then go to Configure > Access Points > Access Points Policies page,
and then clear the Approval check box.
Follow these steps to configure DHCP option 43 on a Linux server.
1 Log on to your DHCP server via a console terminal (for example, PuTTY).
2 Go to /etc directory.
3 Run vi dhcpd.conf. This command opens the DHCP configuration file for
editing.
