The following figure shows how SNMP collection settings control collection at the network, group, and device levels.


Features for enabling and disabling SNMP collection are available in the following locations:

• For the network: On the Network Polling panel (Settings icon > Setup section > Collection and Groups > Global tab).
• For groups: On the Device Groups side tab (Settings icon > Setup section Collection and Groups page > Groups tab > Device Groups side tab).
• For devices: On the Device Viewer's General Settings page (Device Viewer > Settings & Status section > General Settings page).

SNMP Data Collection and Licensing Effects

NetMRI guesses the SNMP credentials of all known network devices that are licensed or unlicensed in the included discovery ranges and collects each SystemInfo table. The device hostname and device type get resolved based on information from the SystemInfo table, enabling the identification of unlicensed network devices in NetMRI. If the device is unlicensed, SNMP collection stops at that point, excluding other data collection, such as Routing, ARP, and interfaces.
