I have a Cisco WLC and different LWAPPs. What I am looking for is a way to be able to get in the WLC the RSSI of all connected clients.

For the moment, I am able to access through SNMP to the AIRESPACE-WIRELESS-MIB on the WLC. There, I can access the bsnMobileStationRssiDataTable, where all the connected clients have an entry, indexed by each LWAPPs. The main problem is that the RSSI update is really slow, like every 3 to 5 minutes.

What I am looking for is for a refresh rate of at least 5 to 10 seconds.

Is there any way of doing this, or is there another MIB where this information can be retrieve?

I am really struggling to get this information through the Cisco forums/websites.

  • Here’s an interesting article on Why RSSI isn't very useful for signal measurements.. “You see the problem with trying to make meaningful conclusions with what amounts to a total pile of crap as a basis?”

To get the RSSI of connected clients, you will need this OID:

.1.3.6.1.4.1.9.9.273.1.3.1.1.3

In regards to graphing the information every 5 or 10 seconds, you could use monitoring software like Cacti to achieve this.

    What @OzNetNerd didn't explicitly say is that you will have to get this info directly from the APs, not from the controller.

  • The problem is that my AP are configure as LWAPs, so i need to do all the snmp poll through the WLC, isn't it ? And I tried to access the OID cDot11ClientSignalStrength in the WLC with no luck.

  • There is a way to get this info using the command line directly into the WLC or the AP ?
