We have a 7210 mobility Controller running 150 access points. I would like to get an alert when an AP goes down.
I understand that there is a AWMS product that can do this but don't have one. I researched on the site and came up with this link that seems to imply I need to walk the MIB continuously to try and find down APs (link) But the whole point of the SNMP trap system is so you don't have to do that, you listen for a report of a problem.
So I assumed that I could use SNMP traps to get an alert from the controller to our WhatsUpGold console for sending out the alerts, and by importing the MIB from the Aruba and configuring them to send and listen for traps it does indeed send some information.
However, the information is fairly useless. It reports that access points are up and down every few seconds - even though none are actually having problems. I had hoped for the name of the AP or at least its IP address, but the traps report only one of the controller addresses.
Am I looking at the wrong thing or can I not use traps with the controller in this instance? THis is pretty frustrating that something so basic is not easy to get at.
One of the SNMP traps from controller:
