SNMP settings

[Kevin Everts_1]

We have been using the default settings for SNMP and have decided to change them. Where do I need to change them on the servers and in Insight Manager? I'm assuming there is a public and a private somewhere to change, right?

Also, should I setup SNMP trap communities as well as destinations or just the settings under 'security'?

You'll have to change the following:
1) change all SNMP settings inside the OS on each server. This is both security and trap destination. You can do this one-by-one, via a .reg-file that you distribute or via the Management Agents (if >= 5.30).
2) create a IM7 control task, that will change the SNMP settings on each device inside his database

3) test your implementation via the Test Trap button in your Control Panel - Management Agents.

Thanks for the help. I am now getting two alerts for each server. How do I make it so I only get one?

On the servers, under the 'Traps' tab, I have both of my community names (i.e. public and private) with the server running Insight Manager as the destination.

Then under the 'Security' tab, I have my public string set to 'READ CREATE' and my private string set to 'READ ONLY' Is this the way it should be?

Anyone?

What's the community string you're using for CIM? You should only have the CIM server under one of them, so if it's under both, that might be why you're getting alerts twice. Also, you should NOT have public set to Read-Create. Public should be Read Only, and set another, unique, community string to Read-Create, and use that for CIM. Even private isn't the greatest idea. You do, however, want the control community that's used for CIM set to Read-Create.
