Determine which MIBs a Specific Node Supports

When troubleshooting a problem, it is helpful to know which MIB files are supported by the troubled Node's SNMP Agent. Then you can determine which MIB Variables are available to help you resolve the problem.

To explore the MIBs supported on a selected Node:

1. Do one of the following:

   • Select the Node in any map or table view.
   • Select an Incident in an Incident view, and navigate to the Incident's Source Node form.

2. Select Actions → MIB Information → List Supported MIBs.

   You can also right-click any object in a table or map view to access the items available within the Actions menu.

3. If SNMP communications between NNMi and the Node are working, you will see the list of MIB files currently supported by the Node's associated SNMP Agent.

   If the menu item List Supported MIBs is greyed-out, NNMi does not have access to SNMP communications with this Node. Contact your NNMi administrator to request Communication Configuration settings that establish SNMP communications with this Node.

4. To learn which information can be provided by each MIB file, do the following:

   • Click the displayed link to open a MIB Form. and explore the contents of that MIB file.
   • Within the MIB form, click Actions → Display MIB File to read the actual source text of the MIB file, if you prefer that format. See Display a MIB File (source text file).
5. See Use the MIB Browser to gather the current MIB Variable values being reported by the SNMP Agent assigned to a Node.
