Here is a quick roundup of the basic command set required to configure your Autonomous Cisco AP from scratch for APoS.

Connect via the console cable

Hostname

Give the AP a name

ap>
ap>enable
Password: Cisco
ap#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
ap(config)#
ap(config)#hostname SURVEY
SURVEY(config)#
SURVEY(config)#end
SURVEY#

Copy

Logging Synchronous

Prevent system messages from appearing in the middle of commands that I am typing.

SURVEY#
SURVEY#conf t
SURVEY(config)#line console 0
SURVEY(config-line)#
SURVEY(config-line)#logging synchronous
SURVEY(config-line)#
SURVEY(config-line)#end
SURVEY#

Copy

I think it is worth applying this command to the vty lines also.

SURVEY#
SURVEY#conf t
Enter configuration commands, one per line. End with CNTL/Z.
SURVEY(config)#line vty ?
    <0-15> First Line number

SURVEY(config)#line vty 0 15
SURVEY(config-line)#logging synchronous
SURVEY(config-line)#
SURVEY(config-line)#end
SURVEY#

Copy

No IP domain-lookup

To prevent accidental incomplete commands being entered and time wasted while the AP attempts to resolve incomplete text strings.

SURVEY#
SURVEY#conf t
Enter configuration commands, one per line. End with CNTL/Z.
SURVEY(config)#no ip domain-lookup
SURVEY(config)#
SURVEY(config)#end
SURVEY#

Copy

Assign an IP address

SURVEY#
SURVEY#conf t
Enter configuration commands, one per line. End with CNTL/Z.
SURVEY(config)#interface BVI ?
    <1-255> BVI interface number

SURVEY(config)#interface BVI 1
SURVEY(config-if)#
SURVEY(config-if)#ip address 192.168.0.1 255.255.255.0
SURVEY(config-if)#
SURVEY(config-if)#end
SURVEY#

Copy

Create an SSID and assign it to the 2.4 GHz radio

For now, the SSID will be configured with no encryption.

Copy

That is our first SSID created, intended for the 2.4 GHz band, we have set the authentication to be open and enabled guest mode for this SSID, so that it will be broadcast.

Next we shall assign the SSID to the 2.4 GHz radio.

SURVEY(config)#
SURVEY(config)#interface dot11Radio 0
SURVEY(config-if)#
SURVEY(config-if)#ssid CISCO-SURVEY 2.4
SURVEY(config-if)#
SURVEY(config-if)#end
SURVEY#

Copy

Channel, Channel width & world-mode

SURVEY#
SURVEY#conf t
Enter configuration commands, one per line. End with CNTL/Z.
SURVEY(config)#interface dot11Radio 0
SURVEY(config-if)#
SURVEY(config-if)#channel 1
SURVEY(config-if)#
SURVEY(config-if)#channel width 20
SURVEY(config-if)#
SURVEY(config-if)#world-mode dot11d country-code GB indoor
    Selected country United Kingdom (UK)

SURVEY(config-if)#end
SURVEY#

Copy

Enable the 2.4 GHz radio interface

Copy

2.4 GHz radio transmit power

SURVEY#
SURVEY#conf t
Enter configuration commands, one per line. End with CNTL/Z.
SURVEY(config)#int dot11Radio 0
SURVEY(config-if)#power local ?
    <3 - 18>  One of: 18 15 12 9 6 3
    maximum   Set power to allowed maximum

SURVEY(config-if)#power local 15
SURVEY(config-if)#end
SURVEY#

Copy

The 2.4 GHz interface is all good now and ready to go. Next I will configure the 5 GHz interface in a similar way.

5 GHz radio interface configuration

Copy

Ok thats it both SSIDs created, basic parameters configured, assigned to their respective radio interface, power level set.

Enable SSH

In the field I find it useful to be able to associate to the AP, with a statically assigned IP address on my laptop and check and or change parameters like the transmit power level by SSH.

Copy

Now SSH to this AP should be possible.

Save the changes we have made

With a good old-fashioned copy run start

SURVEY# SURVEY#copy running-config startup-config Destination filename [startup-config]? Building configuration... [OK] SURVEY#
