I've never been able to get the exact relationship straight but there is an interaction between new node discovery, the "daily" CONFIGURATION poll, the communityNames.conf file and Authentication traps.  It may also be involved with a restart of NetView. 

On discovery you will find NetView taking it's community names from the communityNames.conf file and trying them in turn after trying the default community string.  If the correct one is not the default you will get an authentication trap from the router solicited. (Unless authentication trap forwarding is set off on the Cisco device.) 

This may be happening on your restart.  It would happen if these were new devices in the seed file on the NETMON daemon startup.  I'm not sure about existing devices since they should have an existing defined community string. The documentation doesn't clearly state how that factors into the configuration polling sequence.

I've talked to someone of the telecom department and it seem to  have no error log or something about snmp authentification...

These error seem to have begin when we restart netview (Monday) ....

Is there a relation about restarting netview AND these error ???

Isn't there a log on the router which will tell you why it sent the trap?

Hello All,

we reveive a netview event "trap authenticationFailure" from 3 of our routers. Nothing has been change from Netview.

Why now Netview (sxptiv0009), receive this event from only 3 of our routers ? (Netview try to get some info of these 3 routers and the acces seem to be denied...but when we doing "mib browser" info seem to be there...

Can it be a error in the router configuration even if we know that the community is set ok each both side (router / netview) ?
