Chapter 18 Configuring Repeater and Standby Access Points
Understanding Hot Standby
Understanding Hot Standby
Hot Standby mode designates an access point as a backup for another access point. The standby access
point is placed near the access point it monitors, configured exactly the same as the monitored access
point. The standby access point associates with the monitored access point as a client and queries the
monitored access point regularly through both the Ethernet and the 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 offline and the standby access point takes its
place in the network, matching settings ensures that client devices can switch easily to the standby access
point.
Hot standby mode is disabled by default.
Note If the monitored access point malfunctions and the standby access point takes its place, repeat the hot
standby setup on the standby access point when you repair or replace the monitored access point. The
standby access point does not revert to standby mode automatically.
Configuring a Hot Standby Access Point
When you set up the standby access point, you must enter the MAC address of the access point that the
standby unit will monitor. Record the MAC address of the monitored access point before you configure
the standby access point.
The standby access point also must duplicate several key settings on the monitored access point. These
settings are:
• Primary SSID (as well as additional SSIDs configured on the monitored access point)
• Default IP Subnet Mask
• Default Gateway
• Data rates
• WEP settings
• Authentication Types
Check the monitored access point and record these settings before you set up the standby access point.
Note Wireless client devices associated to the standby access point lose their connections during the hot
standby setup process.
Beginning in Privileged Exec mode, follow these steps to enable hot standby mode on an access point:
Command Purpose
Step 1

Step 2
iapp standby mac-address Puts the access point into standby mode and specifies the MAC
address of the monitored access point.
