Chapter 4 Basic Wireless Device Configuration
Upgrading to Cisco Unified Software
Secure an IP Address on the Access Point
Secure an IP address on the access point so it that can communicate with the WLC and download the
Unified image upon boot up. The host router provides the access point DHCP server functionality
through the DHCP pool. Then the access point communicates with the WLC and setup option 43 for the
controller IP address in the DHCP pool configuration. The following is a sample configuration:
ip dhcp pool embedded-ap-pool
network 60.0.0.0 255.255.255.0
dns-server 171.70.168.183
default-router 60.0.0.1
option 43 hex f104.0a0a.0a0f (single WLC IP address(10.10.10.15) in hex format)
int vlan1
ip address 60.0.0.1 255.255.255.0
For more information about the WLC discovery process, see Cisco Wireless LAN Configuration Guide
at: http://www.cisco.com/en/US/docs/wireless/controller/4.0/configuration/guide/ccfig40.html
Confirm that the Mode Setting is Enabled
To confirm that the mode setting is enabled, perform the following steps.
Step 1 Ping the WLC from the router to confirm IP connectivity.
Step 2 Enter the service-module wlan-ap 0 session command to establish a session into the access point.
Step 3 Confirm that the access point is running an autonomous boot image.
Step 4 Enter the show boot command on the access point to confirm that the mode setting is enabled. The
following is sample output for the command:
# show boot
BOOT path-list: flash:ap802-k9w7-mx.124/ap802-k9w7-mx.124

Performing the Upgrade
To upgrade the autonomous software to Cisco Unified software, follow these steps:
Step 1 To change the access point boot image to a Cisco Unified upgrade image (also known as a recovery
image), issue the service-module wlan-ap 0 bootimage unified command, in global configuration
mode.
Router# conf terminal
Router(config)# service-module wlan-ap 0 bootimage unified
Router(config)# end
