Discovery Scopes and Scope Sets

Discovery scopes identify the resources that you want TSA to discover. Discovery scopes are grouped into discovery scope sets.

You can specify discovery scopes by using an IP address or host name, a range of IP addresses, or a network or subnet to define the resources that are accessed during discovery. A discovery scope can be as small as a single IP address or host name, or as large as a range of IP addresses or a network.

To simplify creation of a scope set, you can import a file that contains a list of IP addresses and host names. For more information, see section Importing a general scope set.

The more IP addresses that are in a discovery scope, the longer the discovery takes. You can modify the discovery size by disabling or enabling discovery scope sets or by excluding IP addresses, ranges of IP addresses, or networks or subnets from a scope within a scope set.

Note: For better performance, limit the cumulative number of IP addresses (IP address, ranges, subnets, and exclusions) in a scope set to 400 or less.

Note: Scopes or import lists that are defined with host names have the host name resolved to an IP address when the scope is created or edited. TSA does not use the host name when discovering network resources.
