9Refining Network Discovery

The procedures in this chapter are optional. You may wish to come back to this

chapter after Network Discovery has been up and running for a while. Here you

will learn how to take advantage of the precision Network Discovery offers you

for setting up Network Discovery.

A precise matrix of network discovery

In chapter 8, Set up Network Discovery on page 95, there were instructions to

set up discovery quickly and simply just to get started. The instructions were

basically to apply the Network Property Group, “Active discovery”, to all of your

IPv4 range or ranges and give them all the same set of community strings.
