Chapter19 Configuring Repeater and Standby Access Points and Wo rkgroup Bridge Mode

Configuring a Hot Standby Access Point

Tip To quickly duplicate the monitored access point’s settings on the standby access point, save the

monitored access point configuration and load it on the standby access point. See the “Working with

Configuration Files” section on page20-8 for instructions on uploading and downloading configuration

files.

Beginning in Privileged Exec mode, follow these steps to enable hot standby mode on an access point:

Command Purpose

Step1 configure terminal Enter global configuration mode.

Step2 iapp standby mac-address Puts the access point into standby mode and specifies the MAC

address of radio on the monitored access point.

Note When you configure a 1200 Series access point with two

radios to monitor a 1200 Series access point with two

radios, you must enter the MAC addresses of both the

monitored 2.4-GHz and 5-GHz radios. Enter the 2.4-GHz

radio MAC address first, followed by the 5-GHz radio

MAC address.

Note The MAC address of the monitored access point might

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.

Step3 interface dot11radio { 0 | 1 } Enter interface configuration mode for the radio interface. The

2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.

Step4 ssid ssid-string Create the SSID that the standby access point uses to associate to

the monitored access point; in the next step designate this SSID

as an infrastructure SSID. If you created an infrastructure SSID

on the monitored access point, create the same SSID on the

standby access point, also.

Step5 infrastructure-ssid [optional] Designate the SSID as an infrastructure SSID. The standby uses

this SSID to associate to the monitored access point. If the

standby access point takes the place of the monitored access

point, infrastructure devices must associate to the standby access

point using this SSID unless you also enter the optional keyword.

Step6 authentication client username

username

password password

If the monitored access point is configured to require LEAP

authentication, configure the username and password that the

standby access point uses when it performs LEAP authentication.

This username and password must match the username and

password that you set up for the standby access point on the

authentication server.

Step7 exit Exit SSID configuration mode and return to radio interface

configuration mode.
