Chapter 19 Configuring Repeater and Standby Access Points and Workgroup Bridge Mode
Understanding Hot Standby
Setting Up a Repeater As a WPA Client
WPA key management uses a combination of encryption methods to protect communication between
client devices and the access point. You can set up a repeater access point to authenticate to your network
like other WPA-enabled client devices.
Beginning in Privileged Exec mode, follow these steps to set up the repeater as a WPA client:
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 sends IAPP
queries to the monitored access point 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.

Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
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.
Step 3
ssid ssid-string Create an SSID and enter SSID configuration mode for the new
SSID. The SSID can consist of up to 32 alphanumeric characters.
SSIDs are case sensitive.
Step 4
authentication open Enable open authentication for the SSID.
Step 5
authentication key-management
wpa
Enable WPA authenticated key management for the SSID.
Step 6
infrastructure ssid Designate the SSID as the SSID that the repeater uses to associate
to other access points.
Step 7
wpa-psk { hex | ascii } [ 0 | 7 ]
encryption-key
Enter a pre-shared key for the repeater.
Enter the key using either hexadecimal or ASCII characters. If
you use hexadecimal, you must enter 64 hexadecimal characters
to complete the 256-bit key. If you use ASCII, you must enter
from 8 to 63 ASCII characters, and the access point expands the
key for you.
Step 8
end Return to privileged EXEC mode.
Step 9
copy running-config
startup-config
(Optional) Save your entries in the configuration file.
