I have LMS 2.6 installed with DFM 2.0.11. Recently, we upgraded the system to support SNMPv3. Running fine for a couple of days, then we noticed that DFM started to timeout certain vlan interface (such as high vlan id, 932-936), then clear, then alarm, then clear for one switch. After I changed DFM config back to SNMPv2c for that switch, everything is running ok. Is this a known bug in DFM related to SNMPv3?
Any help would be greatly appreciated.
