SNMP trap authenticationFailure

Hi everyone.
Can anyone give me an advice about AirWave.
Currently I have installed few aruba controllers and AirWave system to monitor them. From time to time I can see the following snmp traps in AirWave:

Date and timeSNMP Trap----AuthauthenticationFailure


What is that type of trap - is it user auth error, administrator auth error or SNMPv3 authentication error?

What is the whole message from the trap?

Actually, it's a whole message...here is picture next

On the controller type "show snmp trap-queue" to see if you can find it.  Usually the message has much more information than that...

Re: SNMP trap authenticationFailure

That is little funny, but the output from cli for "show snmp trap-queue" command is:
2015-09-23 12:50:23 SNMP Authentication Failed
2015-09-23 12:50:28 SNMP Authentication Failed

Re: SNMP trap authenticationFailure

Okay.  That means something is wrong with the method you are using to poll.  Have you already tried working with snmpv2 successfully?

Re: SNMP trap authenticationFailure

Actually, SNMPv2 displays more information...
Here is output from SNMPv2 trap:
9/23/2015 8:39 AM    SNMP Trap    -    -    -    -    Auth    wlsxNAuthServerIsDown wlsxTrapAuthServerName.0: #########,
wlsxTrapTime: 9/23/2015 8:39:32 UTC-3

 

But it's strange....I thought that SNMPv3 gives the same information as v2. I thought that the only difference is in security parameters..

Re: SNMP trap authenticationFailure

Those look like two different notifications.  One trap is saying that snmp authentication failed.  The other one is reporting an authentication server is down.

Re: SNMP trap authenticationFailure

So you have the SNMPv3 informs configured on the controller for SNMPv3 with a user/password that exactly matches the SNMPv3 settings configured for airwave AND you don't have any auto-SNMPvX discovery settings configured on AirWave? I don't have one handy at the moments but so long as the controller is configured for SNMPv3 informs with the same username/password as what is configured for the SNMPv3 settings on Airwave (of which there are two places to configure), it will work fine without any SNMPv1/2 settings needed. 

 

Remember, two places to configure SNMPv3 for a controller on AirWave:

1. Within the device-specific communications

2. Within the "SNMPv3 Informs" on the "Device Setup > Communications" page

 

The controller should be configured for SNMPv3 Informs on the SNMP settings page.

Re: SNMP trap authenticationFailure

I checked current situation once more...
Now I'm pretty sure, that next error exists only in SNMPv3.

 

Date and timeSNMP Trap----AuthauthenticationFailure


Also, I suspect that it's authentication error of controller and AirWave communication. I meen, that it's just internal SNMPv3 error.
As I found, it appears nearly once per hour and makes auth errors for a 10-15 seconds. Despite that, all other SNMPv3 communication works fine. For now, I'm getting all traps, performing device polling...
What can it be?
To finalize, I'll say, that I currently successfully using SNMPv3 (for test), but once per hour getting authentication Failure.
Also, from time to time, I'm getting next logs (which are in different time according authenticationFailure errors):
