Ciscoworks (LMS 3.2) is gererating SNMP authentication errors for some of our devices (5 out of 838). The typical trap message is as follows:
Authentication Failure - " authAddr.0 (IpAddress): X.X.X.X  snmpTrapEnterprise.0 (Object ID): 18.104.22.168.22.214.171.124.614 " Where X.X.X.X is the Ciscoworks server.
I have confirmed the device credentials are correct in Ciscoworks. I have deleted and re added the devices to the DCR. I have backed up and restored the RME database. I have reinitialised the RME database and I have deleted the devices out of DFM.
Unfortunatly the authentication errors don't match with the time of the scheduled discovery. Discovery runs once a day while we are seeing several dozen to serveral hundred authentication error traps per hour, every hour.
Additionaly I have limited discovery to the one string we use for everything.
