Cisco Systems 1550 Manual De Usuario

This section contains a DHCP Option 43 configuration example on a DHCP server for use with Cisco 
Aironet Access Points. For other DHCP server implementations, consult DHCP server product 
documentation for configuring DHCP Option 43. In Option 43, use the IP address of the controller 
management interface.

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, 1500, and 1552 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 DHCP Vendor 
Class Identifier (VCI) string (DHCP Option 60). The VCI strings for Cisco access points that can operate 
in lightweight mode are listed in 

The following is the format of the TLV block for 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1552 
access points: 

Type: 0xf1 (decimal 241) 

Length: Number of controller IP addresses * 4 

Value: List of WLC management interfaces
