AppendixG 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 o n configuring DHCP

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

URL:

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 Opti on 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 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 embedde d Cisco

IOS DHCP server, follow these steps:

Step1 Enter configuration mode at the Cisco IOS command line inter face (CLI).
