Chapter 20 Configuring Repeater and Standby Access Points and Workgroup Bridge Mode
The MAC address of the monitored access point can change if a BSSID on the
monitored unit is added or deleted. If you use multiple BSSIDs on your wireless
LAN, check the status of the standby unit when you add or delete BSSIDs on the
monitored access point. If necessary, reconfigure the standby unit to use the
BSSID’s new MAC address.
Configuring Hot Standby When you set up the standby access point, you must enter the MAC address of
the access point that the standby unit monitors. Record the MAC address of the
monitored access point before you configure the standby access point.
The standby access point 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 and authentication servers
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. Check the monitored access point and record
these settings before you set up the standby access point.
The standby access point monitors another access point in a device-to-device
relationship, not in an interface-to-interface relationship. For example, you
cannot configure the standby access point's 5 GHz radio to monitor the 5 GHz
radio in access point alpha and the standby's 2.4 GHz radio to monitor the
2.4 GHz radio in access point bravo. You also cannot configure one radio in a
dual-radio access point as a standby radio and configure the other radio to serve
client devices.
TIP Hot standby is not supported on the BR1410 configured for AP mode.
TIP Wireless client devices associated to the standby access point lose their
connections during the hot standby setup process.
