We've been using NPM to monitor our nortel and avaya ers switches using snmp v1&2 for some time now with no problems... As part of our increased security initiatives we're planning to move to snmp v3. Has anyone had any success doing this? Our lab tests so far have been complete failures having used all the available documentation from both Avaya, Avaya communities and Solarwinds. Syslog entries if they show anything at all just show an "unauthorized SNMP" attempt from the NPM server.
Switches are ERS 5xxx and NPM 10.4.1
Any help or suggestions would be greatly appreciated, trying to avoid bashing my head against the wall with tech support from either company!
