We recently installed 4 new 4100 Silkworm switches. I noticed our snmp traps were filling the logs with authentication failure. After setting up SNMPv3, this cleared the problem, but MRTG does not use SNMPv3, so I have to revert back to SNMPv1. How do you change back to SNMPv1? The switch does support it. Everytime I setup the comm string, etc for SNMPv1 and remove the settings for SNMPv3, I start to receive the auth failure.
