Appendix F Configuring Dhcp Option - Cisco Aironet 1550 Series Hardware Installation Manual

Overview
Overview
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.
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, 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
