13Configuring DHCP Option 43 and DHCP Option 60

This section contains a DHCP Option 43 configuration example on a Windows 2003 Enterprise DHCP server for use with Cisco Aironet lightweight access points. For other DHCP server implementations, consult product 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.

The 3700 series access point uses 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 string for the 3700 series access point is:

Cisco AP c3700

Note If your access point was ordered with the Service Provider Option (AIR-OPT60-DHCP) selected in the ordering tool, the VCI string for the access point contains ServiceProvider. For example, a 3700 with this option will return this VCI string:

Cisco AP c3700-ServiceProvider

The format of the TLV block is listed below:

•Type: 0xf1 (decimal 241)

•Length: Number of controller IP addresses * 4

•Value: List of WLC management interfaces

To configure DHCP Option 43 in the embedded Cisco IOS DHCP server, follow these steps:
