Chapter 19 Configuring Repeater and Standby Access Points and Workgroup Bridge Mode
Aligning Antennas
The following example shows how to set up a repeater access point with three potential parents,
designated 1 to 3:
AP# configure terminal
AP(config)# interface dot11radio 0
AP(config-if)# ssid chicago
AP(config-ssid)# infrastructure-ssid
AP(config-ssid)# exit
AP(config-if)# station-role repeater
AP(config-if)# dot11 extensions aironet
AP(config-if)# parent 1 0987.1234.h345
AP(config-if)# parent 2 7809.b123.c345
AP(config-if)# parent 3 6543.a456.7421
AP(config-if)# end
This example shows how to remove a parent, here parent 2, from the parent list:
AP(config-if)# no parent 2
This example shows how to set a timeout of 60 seconds for the parent list:
AP(config-if)# parent timeout 60
This example shows how to disable the timeout value for the parent list:
AP(config-if)# no parent timeout
Aligning Antennas
When an access point is configured as a repeater, you can align its antenna with another remote antenna
using the dot11 antenna-alignment CLI command.
The command invokes an alignment test. The radio disassociates from its parent, probes adjacent
wireless devices, and records the MAC addresses and signal strengths of responses it receives. After the
timeout, the radio reassociates with its parent.
Follow these steps to run an antenna alignment test:
Step 9
end Return to privileged EXEC mode.
Step 10
copy running-config
startup-config
(Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1
enable Enter privileged EXEC mod
Step 2
dot11 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 3
antenna-alignment timeout Establish the time in seconds that the antenna alignment test runs
before timing out. The default is 5 seconds.
