Chapter 19 Configuring Repeater and Standby Access Points and Workgroup Bridge Mode
Aligning Antennas
Use the show dot11 antenna-alignment command to list the MAC addresses and signal level for the
last 10 devices that responded to the probe.
Verifying Repeater Operation
After you set up the repeater, if your repeater is functioning correctly, the repeater access point should
appear associated with the root access point in the root access point's Association Table.
Setting Up a Repeater As a WPA2 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 WPA2-enabled client devices.
Beginning in Privileged Exec mode, follow these steps to set up the repeater as a WPA2 client:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ssid ssid-string Associate the SSID to the radio interface.
Step 3
authentication open Enable open authentication for the SSID.
Step 4
authentication key-management
wpa
Enable WPA authenticated key management for the SSID.
Step 5
infrastructure ssid Designate the SSID as the SSID that the repeater uses to associate
to other access points.
Step 6
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 7
exit Exit the SSID configuration sub-mode.
Step 8
interface dot11radio { 0 | 1 } Enter interface configuration mode for the radio interface.
The 2.4-GHz radio and the 2.4-GHz 802.11n radio is 0.
The 5-GHz radio and the 5-GHz 802.11n radio is 1.
Step 9
encryption mode ciphers
aes-ccm
Enable AES CCMP encryption on the radio interface.
Step 10
end Return to privileged EXEC mode.
Step 11
copy running-config
startup-config
(Optional) Save your entries in the configuration file.
