Whenever one of my C2960's reboot, our Solarwinds monitoring stops working. I found that this is due to one line of SNMPv3 config changing by itself. This used to be in the config:
snmp-server group XXX v3 priv access permit-snmp
(permit-snmp being the access-list defining ip addresses allowed to query) After the reboot, snmpv3 stops working and this line shows up in the config instead of the one above:
snmp-server group XXX v3 priv notify *tv.FFFFFFFF.FFFFFFFF.FFFFFFFF.FFFFFFFF7F
Is this a bug? (I did check the bug database, without success.) I have upgraded the IOS to 12.2(53) SE2 without any success. The switch is a C2960-24TC-L.
