Can NNMi support devices has no community strings.

Jump to solution

Dears,

I'm now trying to add a VMAX storage box to be monitored by NNM, VMAX is not determining community strings as only you have to add the IPs where the traps will be send to only without defining any community strings.

I performed a SNMP walk and it's failed.

Is the NNM working this way? and if yes how can I descover the device?

Thanks.

Ahmed,

  The SNMP protocol ( versions 1 and 2 ) require a community string to be configured - even if it is ignored by the agent.   Since the snmpwalk command failed then it would appear that the device does expect a certain community string, or it simply won't respond to an SNMP request.    If its the former then you need to figure out what it is expecting, if its the latter then NNMi can discover the device as a "non-snmp" device and monitor it via it's IP address using icmp.   In this mode NNMi will still be able to receive the traps from the device - note NNMi does not check the community string in the trap, so they will be received and displayed if configured and enabled.

   Hope this helps

Thanks Dave, It already discovered the device as non-snmp, also the VMAX is not in the NNM support matrix.
