Discovering the SNMP profile of the device

A node that is running an SNMP agent is SNMP-manageable. NetCrunch can monitor nodes using SNMP.

Network discovery process

During network discovery, you can specify that SNMP-manageable nodes be discovered. In such a case, NetCrunch identifies the SNMP-manageable nodes, enables SNMP monitoring in the program for those nodes, and adds them to the SNMP tab of the Atlas window.

SNMP management properties

Changing the SNMP management properties on selected nodes is done from the SNMP tab of the Properties window. When the SNMP manageable host option is enabled, the node will appear in the SNMP view of the Main window, and the user can modify the additional parameters required to manage SNMP information for the selected node.

If SNMP management for a node is enabled, the node will appear in the SNMP view of any map. If the correct Read SNMP Properties are specified in the SNMP profile, then the SNMP information of the node can be viewed by opening the SNMP View window.

If the correct Write SNMP Properties are specified in the SNMP profile, you can modify some SNMP information of the node.

Discovering the SNMP Profile

You can check and manage SNMP profiles for the devices in the Atlas:

1. From the toolbar menu, select Settings->Monitoring->Node Monitoring Defaults.
2. Verify the profile under the SNMP section.
3. Click the Manage SNMP Profiles link to view/edit SNMP profile details. You can also add a new SNMP profile by clicking the Add button.
4. Click OK to save the changes.
