Configuring DHCP Option 43
You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling
each access point to find and join a controller. This section contains a DHCP Option 43 configuration
example on a Microsoft Windows 2003 Enterprise DHCP server for use with Cisco Aironet
lightweight access points.
Additional information about Microsoft DHCP Option 43 is available on Cisco.com at the following

Note In DHCP Option 43, you should use the IP address of the controller management interface.
Note DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a
separate DHCP pool for each access point type.
Cisco Aironet 1000 and 1500 (1505 and 1510) series access points use a comma-separated string
format for DHCP Option 43. Other Cisco Aironet access points use the type-length-value (TLV)
format for DHCP Option 43. DHCP servers must be programmed to return the option based on the
DHCP Vendor Class Identifier (VCI) string (DHCP Option 60) of the access point. The VCI strings for
Cisco access points capable of operating in lightweight mode are listed in
Table 1:
