Appendix G

Configuring DHCP Option 43 for Lightweight Access Points

Overview

This section contains a DHCP Option 43 configuration example on the embedded Cisco IOS DHCP

server for use with Cisco Aironet lightweight access points. For instructions on configuring DHCP

Option 43 on Microsoft, Sun Solaris, Linux, and Lucent QIP DHCP servers, consult the document at this

URL:

http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00808714f

e.shtml

For other DHCP server implementations, consult the DHCP server documentation for configuring DHCP

Option 43. In 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 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 access point’s DHCP Vendor Class

Identifier (VCI) string (DHCP Option 60). The VCI strings for Cisco access points capable of operating

in lightweight mode are listed in

Table G-1

The format of the TLV block for 1100, 1130, 1200, 1240, and 1300 series access points is listed below:

•

Type: 0xf1 (decimal 241)

•

Length: Number of controller IP addresses * 4

•

Value: List of WLC management interfaces
