Appendix G Configuring DHCP Option 43 for Lightweight Access Points

Overview

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 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:

Table G-1	Lightweight Access Point VCI Strings

Access Point		Vendor Class Identifier (VCI)

Cisco Aironet 1000 series		Airespace.AP1200

Cisco Aironet 1100 series		Cisco AP c1100

Cisco Aironet 1130 series		Cisco AP c1130

Cisco Aironet 1200 series		Cisco AP c1200

Cisco Aironet 1240 series		Cisco AP c1240

Cisco Aironet 1300 series		Cisco AP c1300

Cisco Aironet 1500 series		Cisco AP.LAP1510

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

•Type: 0xf1 (decimal 241)

•Length: Number of controller IP addresses * 4

•Value: List of WLC management interfaces

Configuring Option 43 for 1000 Series Access Points

To configure DHCP Option 43 for Cisco 1000 series lightweight access points in the embedded Cisco IOS DHCP server, follow these steps:

Step 1 Enter configuration mode at the Cisco IOS command line interface (CLI).
