Setting up discovery scopes

Set up discovery scopes to specify the IP address, range of IP addresses, or network or subnet to be used during discovery. Discovery scopes are grouped into discovery scope sets.

About this task

Tips: There are some practical considerations for setting up discovery scopes and scope sets.
  • The more IP addresses that are in the discovery scope, the longer the discovery takes. You can modify the discovery size by disabling or enabling scope sets or by excluding IP addresses, IP address ranges, or networks or subnets from a scope within a scope set.

    To minimize the time that a discovery takes, set up discovery scopes to target only those elements that you want to discover and disable scope sets or exclude IP addresses, IP address ranges, or networks or subnets that you do not want or need to discover.

  • Not all elements are equal. For example, a router with dozens of interfaces takes longer to fully discover than a single host.
  • Elements can belong to multiple scopes and scope sets. For example, the same IP address can be part of several different scopes.
    The following list contains examples for grouping elements into scope sets:
    • Group like elements. For example, include all AIX® hosts in a scope set.
    • Group all elements in a location. Because many users manage locations as an entity, specify a scope set that includes the entire location.

Procedure

  1. In the navigation pane, click Discovery Scopes. The Discovery Scopes page is displayed.
  2. To define a new discovery scope set, click Add New Scope Set. The Discovery Scope Set page is displayed.
    1. For Describe Scope Set, in the Scope set name field, enter a unique scope set name.
    2. Click Save. The new scope set is created and the Discovery Scopes page is displayed.
  3. To add a scope to the new scope set, in the Select Discovery Option pane, specify one of the following options:
    • Single IP address or Host

      For Describe Address or Host, enter the IP address.

    • Range of IP addresses

      For Describe Address Range, enter the starting IP address, ending IP address, and optionally, a description in the fields provided.

    • Network or Subnet

      For Describe Network or Subnet, enter the IP address, mask, and optionally, a description in the fields provided.

  4. If you want to exclude hosts, IP addresses, or subnets from the discovery, click Add Exclusion and follow these steps:
    1. Select Host, Range, or Subnet.
    2. Specify the IP address, range of IP addresses, or subnet that you want to exclude from the discovery.
    3. Optional: Specify a description for the IP address, range of IP addresses or subnet that you are excluding from the discovery.
      Note: You cannot reuse an IP address, range of IP addresses, subnet, or description in any scopes or exclusions in a scope set.
    4. To add more exclusions, click Add Exclusion and follow the previous steps to define more exclusions.
  5. Click Save to save the scope and exclusions.
    The Discovery Scope Set page is displayed with the new scope in the list.
  6. To add more scopes to this scope set, click Add New Scope and follow the previous steps to define more scopes.
