Monitor an HP Tape Library/SNMP

[lofti_213]

Hello,
My NetXMS server (2.0.5) is running on WIndows Server 2008 and i want to monitor an HP MSL 4048 Tapelibrary with SNMP.
I created the appropriate node with deactivating agent polling, configured the MSL with the appropriate SNMP community which is configured in the MSL Management Network.
But, every minute, i get : SNMP_AUTH_FAILURE.
I would be so grateful if anyone can share a tip that helps resolving this problem.
Thanks in advance.

Hi,

seems that configuration still mismatch. Double check community on device and in node properties in NetXMS. Also make sure that NetXMS server IP address is listed as allowed in device SNMP configuration.

here are screenshots of my configuration :

Did configuration poll detect MSL node as SNMP node? If yes, it could be some other server trying to communicate with MSL over SNMP, and MSL just sending SNMP authentication failure traps to NetXMS server (because it is configured so).

here is the full configuration poll :

Besides, i get a different trap which is like the picture joint to this.
About your first question, no, it doesn't see the MSL as SNMP node.

Can you communicate with the library using command line tool (nxsnmpwalk or nxsnmpget)? For example

nxsnmpwalk -v2c -c your_community ip_address .1.3.6.1.2.1.1

also try community "public".

Hello Sir,
I believe that setting community string to default "public" resolved my issue in my MSL. But i wonder what was the problem with it..?

Hi,

looks like MSL uses "public" as community ignoring configuration settings. Quick search found description of similar issue: https://thwack.solarwinds.com/thread/33561. If this is the case then it's a bug in MSL firmware.
