Information About Autonomous Access Points Converted to
Lightweight Mode
You can convert autonomous Cisco Aironet access points to lightweight mode. When you upgrade the access
points to lightweight mode, the access point communicates with the switch and receives a configuration and
software image from the switch.
See the Upgrading Autonomous Cisco Aironet Access Points to Lightweight Mode document for instructions
to upgrade an autonomous access point to lightweight mode:
http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html

Reverting from Lightweight Mode to Autonomous Mode

After you convert an autonomous access point to lightweight mode, you can convert the access point from a
lightweight unit back to an autonomous unit by loading a Cisco IOS release that supports autonomous mode
(Cisco IOS Release 12.3(7)JA or earlier releases). If the access point is associated with a switch, you can use
the switch to load the Cisco IOS release. If the access point is not associated to a switch, you can load the
Cisco IOS release using TFTP. In either method, the access point must be able to access a TFTP server that
contains the Cisco IOS release to be loaded.

Using DHCP Option 43 and DHCP Option 60

Cisco Aironet access points use the type-length-value (TLV) format for DHCP option 43. You must program
the DHCP servers to return the option based on the access point's DHCP Vendor Class Identifier (VCI) string
(DHCP option 60).
For more information about DHCP VCI strings of access points, see
tk809/technologies_configuration_example09186a00808714fe.shtml.
See the product documentation for your DHCP server for instructions on configuring DHCP option 43. The
Upgrading Autonomous Cisco Aironet Access Points to Lightweight Mode document contains example steps
for configuring option 43 on a DHCP server.
If the access point is ordered with the Service Provider Option - AIR-OPT60-DHCP selected, the VCI string
for that access point will be different than those strings listed in the previous table. The VCI string has the
following suffix: ServiceProvider. For example, a 1260 with this option returns this VCI string: Cisco AP
c1260-ServiceProvider.

wireless LANs with IDs 1 through 16 are pushed to the access point unless the access point is a member
of an access point group.
