Configuring the Access Point in Hot Standby Mode

Configuring the Access Point in Hot Standby Mode

In hot standby mode, an access point is designated as a backup for another access point. The standby access point is placed near the access point that it monitors and is configured exactly like the monitored access point. The standby access point associates with the monitored access point as a client and sends Internet Access Point Protocol (IAPP) queries to the monitored access point through the Ethernet and radio ports. If the monitored access point fails to respond, the standby access point comes online and takes the monitored access point’s place in the network.

Except for the IP address, the standby access point’s settings should be identical to the settings on the monitored access point. If the monitored access point goes off line and the standby access point takes its place in the network, matching settings ensure that client devices can switch easily to the standby access point. For more information, see Hot Standby Access Points at: http://www.cisco.com/en/US/docs/routers/access/wireless/software/guide/RolesHotStandby.html.

Upgrading to Cisco Unified Software

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

•Preparing for the Upgrade, page 4-9

•Performing the Upgrade, page 4-10

•Downgrading the Software on the Access Point, page 4-11

•Recovering Software on the Access Point, page 4-12

Software Prerequisites

•Cisco 880 Series ISRs with embedded access points are eligible to upgrade from autonomous software to Cisco Unified software, if the router is running the advipservices feature set and Cisco IOS 15.1.(4)M software.

•To use the embedded access point in a Cisco Unified Architecture, the Cisco Wireless LAN Configuration (WLC) must be running version 15.1.(4)M.

Preparing for the Upgrade

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

•Secure an IP Address on the Access Point, page 4-10

•Confirm that the Mode Setting is Enabled, page 4-10
