RE: [nv-l] netmon and SNMP communities

["Federico Vidal" <fvidal@tecsystem.com.ar>]

Sorry, I forgot to mention but I do have all the addresses configured in xnmsnmpconf. It is fully confiugred to poll correctly every device in the net. That's ok, I can check that snmpwalking every device without errors. But....all entries were IMPORTED, if it is relevant to say, with xnmsnmpconf -imp file command (is this an issue??).

 

I want to mention that Netview was working fine UNTIL the IP address change. After then, the netmon polling fails.

 

No, there are no entries in communityNames.conf.

 

thanks

Your question is confusing. If you can walk it, and they are not using the default, then there must be specific entries in xnmsnmpconf for the node. But those entries do not get put in there until the node is discovered. Do you have the alternate communities listed in the /usr/OV/conf/communityNames.conf file? Those are used at discovery and at demandpoll to add specific entries in xnmsnmpconf.

Cordially,

Hello List:

I have a customer with Netview 7.1.3 on Linux who tries to discover his network with it. The thing is that, having a seed file that only discovers SNMP devices ( !@oid 0 ), he can't discover any device beside the ones using the default community. Any device that has another SNMP community different than the default, can't be discovered.

I will give full details: Looking into the matter, i found that the SNMP configuration (xnmsnmpconf) is correct because I can manually poll these devices using snmpwalk without specifying community. I found that netmon is the one who is using wrong communities to poll because the cisco agents in the network keep telling that netview causes authentication failure, thus netview doesnt discover any device due to the seed file.

This is very strange to me, because i thought that the netview engine used the same snmp configuration that CLI commands.

Another detail is that before this problem occurred, my customer changed the netview's IP address, so I ran reset_ci to solve the apparent problem but nothing happenned....

What could be happening???? My last resort is to deinstall but I would like to solve this issue as a Netview supporter.

Thanks in advance.
