Appendix G Configuring DHCP Option 43

Overview

Overview

This section contains a DHCP Option 43 configuration example on a Windows 2003 Enterpr ise D HCP

server for use with Cisco Aironet lightweight access points. For other DHCP server imp lemen tati ons,

consult DHCP server product documentation for configuring DHCP Option 43. In Option 43, you sho uld

use the IP address of the controller management interface.

Note DHCP Option 43 is limited to one access point type pe r DHC P po ol. 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 acc ess points capable of operating

in lightweight mode are listed in Table G-1:

The format of the TLV block for 1100, 1130, 1200, 1240, 1250, and 1300 seri es a cce ss p oint s is l isted
