SNMPv3 Trap / Trap Viewer

jkloza Dec 21, 2012 8:43 AM

Hello all,

I've recently upgraded to solarwinds NPM 10.4, and am having some issues with SNMPv3 trap collection. I'm receiving the message under alerts - "bad trap packet received from node X.X.X.X, decryption of the incoming packet failed, local user credentials are not the right ones, or the packet is malformed".

Everything tests fine in the node configuration, it looks as if the nodes are being monitored properly, but I don't see any traps in the trap viewer being generated. I know my devices are sending the traps, but I'm not sure what's happening afterwards.

Anyone seen anything like this in the past, and can point me in the right direction?

My SNMPv3 configs look like this -

snmp-server group Solarwinds v3 priv read adminview

snmp-server view adminview internet included

snmp-server user adminsolarwinds solarwinds v3 auth sha adminpasssword priv des adminpassword

I can verify, and add devices to the Network Performance Monitor, but I don't see any traps being sent in the trap viewer. Something is most definately not right, I just can't figure out what it is.

Thanks -

Jon

Can you also post your snmp-server host here? That's the one responsible for traps configuration.

  Sorry for the late response, with the holiday and all everything was crazy. My SNMP host configuration follows.
  
  snmp-server host X.X.X.X version 3 priv adminsolarwinds
  
  Thanks,

    Hmm, that should be correct. Are you able to collect a WireShark capture containing a couple of incoming traps from affected device and open a support ticket?

Try the syntax below:

snmp-server view adminview internet included
snmp-server group Solarwinds v3 priv read adminview write adminview notify adminview
snmp-server user adminsolarwinds solarwinds v3 auth sha adminpasssword priv aes 128 adminpassword
snmp-server host 192.168.0.1 version 3 priv adminsolarwinds
