network, matching settings ensure that client devices can switch easily to the standby access point. For more

Upgrading to Cisco Unified Software

To run the access point in Cisco Unified mode, upgrade the software by performing the following procedures:

Software Prerequisites

•

Cisco 890 Series ISRs with embedded access points can be upgraded from autonomous software to

Cisco Unified software, if the router is running the IP Base feature set and Cisco IOS 12.4(22)YB

software.

•

Cisco 880 Series ISRs with embedded access points can be upgraded from autonomous software to

Cisco Unified software, if the router is running the advipservices feature set and Cisco IOS 12.4(20)T

software.

•

To use the embedded access point in a Cisco Unified Architecture, the Cisco Wireless LAN Configuration

(WLC) must be running version 5.1 or later.

Preparing for the Upgrade

Perform the tasks in the following sections to prepare for the upgrade:

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. The access point then communicates with the WLC and setup option 43 for the controller IP address in

the DHCP pool configuration.

Example Configuration: Secure an IP Address on the Access Point

The following example shows 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:

Confirm that the Mode Setting is Enabled

To confirm that the mode setting is enabled, perform the following steps.
