    • Limit Linux discovery to specific network adapters and their primary IP addresses to improve performance by ignoring secondary IP addresses.

    About this task

    Configuring the network_adapter_exclusion_list system property ensures that only specified network adapters and their primary IP addresses are used during Linux discovery. Secondary IP addresses that are not named are automatically omitted.

    Before you begin

    Role required: admin

    Procedure

    1. In the navigation filter, enter sys_properties.list.
    2. In the Name field, search for network_adapter_exclusion_list.
    3. Select the network_adapter_exclusion_list property.
    4. In the Value field, enter the network adapter associated with the NIC IP address to exclude it from deletion.
      The network adapter must be entered in one of the formats listed in the following table.
      Format Description
      Single name Single adapter name. For example: bond0.
      Regular expression matching multiple adapter names Regular expression that matches multiple adapter names ending with one or more digits. For example: bond\d+.
      Multiple adapter names Multiple adapter names, separated by commas, including regular expression. For example: nic1,bond\d+.
    5. Select Update.

    Result

    When the predefined schedule triggers the Linux server discovery or a scheduled horizontal discovery runs, only the specific network adapters and their primary IP addresses are included in the discovery process.
