About SNMP Demand Polls

Perform an SNMP demand poll for a new managed device if you do not want to wait for the next automatic topology poll. HPOV performs less frequent automatic topology demand polls as your network and the HPOV device database becomes more static.

When the HPOV daemons start, HPOV discovers the devices in your network. Depending on which discovery options are configured, the device map is based on Layer 2 or Layer 3 information. Choosing discovery options is outside the scope of this document.

Depending on the number of devices that need to be discovered, it could take hours or even days for HPOV to discover a device. If HPOV cannot find a device, enter the device manually in to the database. See the “Using the HPOV CLI to Enter a Device into the Database” section on page 115.

To organize and adjust the top-level map, see the “Creating and Adjusting Maps” section on page 111.

Performing an SNMP Demand Poll

To perform an SNMP demand poll, follow these steps:

Step 1 From the Root screen, double click the planet Earth Internet icon.

Step 2 Inspect the top-level map of the discovered devices in your network.
