3.3 Configuring network discovery
As you begin to use NNMi to discover and manage your network, it is a good practice to start with a test network and configure NNMi to discover and manage a few nodes with only a few interfaces. The Quick Start Configuration Wizard (see 2.2 Using the Quick Start Configuration Wizard) provides an easy way to set up this type of small configuration. We recommend that you use the Quick Start Configuration Wizard immediately after installing NNMi.
As you become more familiar with NNMi, you will understand how its rich set of features applies to managing your network. You can expand the network topology that NNMi manages over time, systematically adding new discovery rules and putting new areas under management.
The topics in this section provide a brief overview of the configuration tasks that are required before initiating the discovery process. The checklist in the following table summarizes these tasks.
Completed? (y/n) |
Task |
|---|---|
Verify that all nodes to be discovered are connected to the network and configured with a supported version of SNMP (SNMPv1, SNMPv2c, or SNMPv3). |
|
Obtain read-only community strings from your network administrator for the nodes that you plan to manage. |
|
Using the NNMi console, configure community strings as described in 3.3.1 Configuring community strings. |
|
Using the NNMi console, configure the spiral discovery process as described in 3.3.2 Configuring auto-discovery rules. |
|
Using the NNMi console, check the spiral discovery progress as described in 3.3.3 Checking discovery progress. |
For details about the discovery process, see Discovering Your Network in NNMi Help.
