Chapter 4 Management Mode

4.1.1 CAPWAP Discovery and Management

The link between CAPWAP-enabled access points proceeds as follows:
An AP in managed AP mode joins a wired network (receives a dynamic IP
1
address).
The AP sends out a management request, looking for an AP in CAPWAP AP
2
controller mode.
If there is an AP controller on the network, it receives the management request.

4.1.2 CAPWAP and DHCP

CAPWAP managed APs must be DHCP clients, supplied with an IP address by a
DHCP server on your network.
Furthermore, the AP controller must have a static IP address; it cannot be a DHCP
client.

4.1.3 CAPWAP and IP Subnets

By default, CAPWAP works only between devices with IP addresses in the same
subnet (see the appendices for information on IP addresses and subnetting).
However, you can configure CAPWAP to operate between devices with IP
addresses in different subnets by doing the following.
• Activate DHCP option 43 on your network's DHCP server.
• Configure DHCP option 43 with the IP address of the CAPWAP AP controller on
your network.
