Introduction

 

Basic Cisco AP Debugging - Autonomous IOS. These are debugs that you can collect while logged into the IOS CLI.

 

Basic setup

 

If you see a prompt that ends in a right angle bracket, like this:

 

ap>

 

it means that you are in unprivileged mode, so get privileged (which shows a # prompt):

 

ap>enable

Password:

ap#

 

(default username/password on APs is "Cisco".)

 

Configure NTP, timestamp's, line timeout

 

ap#configure terminal

ap(config)#sntp server 1.2.3.4

ap(config)#service timestamp debug datetime msec

ap(config)#service timestamp log datetime msec

ap(config)#logging rate-limit 500

ap(config)#no logging console

[1]

 

ap(config)#line con 0

ap(config-line)#no exec-timeout

ap(config-line)#line vty 0 4

ap(config-line)#no exec-timeout

ap(config)#exit

ap#write   (if you wan to to save the configuration changes to NVRAM)

 

 

[1] if you're going to generate debug messages at an extremely high rate, should be sure to turn off console logging, otherwise the AP will hang.  (If your access is via the console, then of course you would need some other way to see the debugs then - e.g.write them to a logging buffer, or to an external syslog server Or increase the console port speed to 115200 )

 

Collecting debugs from telnet or ssh session

 

Telnet/ssh into the AP, then enter the command "terminal monitor".  The debug messages will be written to your terminal window.  To save the messages, configure your terminal emulator accordingly.

 

Collecting debugs from a console session

 

Some development special debug output will be written only to the console.  So in such a case, you must connect a serial cable to the AP's console port and access this cable via a terminal emulator program (e.g. Windows Hyperterminal talking to a PC COM port.)  The default console port speed is 9600 bps which is too slow to collect a large volume of debugs - so increase the speed to 115200 bps, its maximum:

 

ap#configure terminal
ap(config)#logging console
ap(config)#line con 0
ap(config-line)#no exec-timeout
ap(config-file)#speed 115200

at this point, the terminal emulator program on the serial line will no longer be able to communicate with the console port, till you reset its speed to 115200 bps to match.

 

Radio names

 

The radios are usually called Dot11Radio0 (2.4GHz) and Dot11Radio1 (5GHz.)

 

 

ajax#show ip int brief
Interface                  IP-Address      OK? Method Status                Protocol
BVI1                       10.0.47.21      YES DHCP   up                    up 
Dot11Radio0                unassigned      YES unset  up                    up 
Dot11Radio1                unassigned      YES unset  administratively down down
FastEthernet0              unassigned      YES other  up                    up

You can abbreviate them to do0 and do1:

ajax#show controller do0
[...]
Radio AIR-AP1131G, Base Address 0012.44b3.e000, BBlock version 0.00, Software version 6.20.6
[...]
Configured Frequency: 2442 MHz  Channel 7

 

Basic show commands

 

radio information

 

ajax#show interface dot11radio0
ajax#show controller dot11radio0

 

client information

 

ajax#show dot11 associations
ajax#show dot11 associations all

 

AP information

 

ajax#show config     <= configuration (from NVRAM)
ajax#show run          <= configuration (in memory)
ajax#show version     <= model, version info
ajax#show tech          <= everything - do "term length 0" first

 

Other basic commands

 

ajax#clear dot11 client 0011.2233.4455  <= deauthenticate a client
ajax#clear int dot11radio0              <= reset a radio
ajax#reload                    <= reboot the AP

 

Basic debug commands

 

radio debugs

 


ajax#no debug dot11 dot11radio0 print printf  <=sometimes necessary for radio debugs to log correctly
ajax#debug dot11 dot11radio0 trace print ?    <= show list of flags
-- example:
-- debug dot11 dot11radio0 trace print mgmt keys  <= mgmt frames & keying

 

dot1X/WPA keying/RADIUS debugs

 

ajax#debug dot11 aaa authenticator state-machine
ajax#debug dot11 aaa authenticator txdata
ajax#debug dot11 aaa authenticator rxdata
ajax#debug dot11 aaa manager keys
ajax#debug radius

 

Example debug output

 

This example uses all of the above listed debugs (except "dot11 aaa manager keys").  This shows a client being deauthed, then successfully associating in LEAP with WPA2/AES.  Note that the messages aren't all logged in order, i.e. the 802.11 association response sent by the AP is logged after the EAP ID-Request message is logged.
