I'm working with several cisco 1200 series APs, trying to get relevant client information off of them. It would be helpful to see RSSI and SNR for individual clients connected, but I am unable to find any commands that are related to this. I've checked around the cisco forums, and a lot of people were able to find this info using some perl scripts along with information from end user wireless cards, but that is not an option for me. I have remote access only to the APs. Other posts recommend using some kind of wireless controller to view this, but that is also not an option. Any suggestions are appreciated.

  • You state that using a Wireless Controller is out of the question, are these "Autonomous" Access Points? That is to say, is there no Wireless Controller in your environment, or you don't have access to the Controller? – Brett Lykins Nov 16 '13 at 0:59

You state that a Wireless Controller is not an option, so I'm assuming these are Autonomous Access Points.

On Cisco Autonomous APs, you are looking for the show dot11 associations command and it's associated sub commands.

It gives an output like so:

SPARKY#show dot11 associations                                  

802.11 Client Stations on Dot11Radio0: 

SSID [sparky] : 

MAC Address    IP address      IPV6 address     Device        Name     Parent         State 
XXXX.da1d.1b05    ::               unknown       -        self           Assoc
XXXX.2c90.c42f    ::               unknown       -        self           Assoc
XXXX.59c0.4ac4    ::               unknown       -        self           Assoc

Once you have the MAC address of your client, you can run the show dot11 associations <MAC ADDRESS> command where <MAC ADDRESS> is the MAC address of the client you're interested in. It should give you all the information you're after. You can also run show dot11 associations all-client and see this information for all associated clients. See the below sample:

SPARKY#show dot11 associations XXXX.da1d.1b05

  • Yes they are all autonomous, there is no controller installed at the site. And thanks, these are exactly the commands I was looking for. Seriously, you just saved myself and co-workers a lot of headache – walkerboh8806 Nov 16 '13 at 1:10
