Specifying IP addresses to find using the File finder

Use the File finder with feedback to configure an efficient discovery that can be used on an ongoing basis in production.

About this task

You have now created a seed list containing just the devices in your discovered topology. You are now going to configure the File finder to use this file as your seed list. You must also make the following changes to your discovery configuration to ensure that you have an efficient production discovery that completes more quickly than your initial discoveries:
  • Switch off ping sweeping of your scope zones.
  • Ensure that the Ping finder is still enabled. You need the Ping finder to verify the existence of devices in your File finder seed list and to ping newly discovered devices connected to your seed devices.
  • Ensure that feedback is switched on. You need feedback on in order to discover new devices connected to your seed devices.

Procedure

  1. Click the Discovery icon and select Network Discovery Configuration.
  2. From the Domain list, select the required domain.
  3. Switch off ping sweeping of your scope zones.
    1. Click Scope.
    2. For each include scope in the Scope Configuration table, click on the Address field.
    3. In the Scope Properties window, uncheck the Add to Ping Seed List option.
    4. Repeat this for each include scope in the Scope Configuration table.
  4. Ensure that the Ping finder is still enabled.
    1. Click Seed.
    2. Check that Use Ping Finder in Discovery is checked.
  5. Configure the File finder.
    1. Check the Use File Finder in Discovery option.
    2. In the File finder section of the GUI. click New New button
    3. In the Filename field of the File Seed Properties window, type the path to the device seed list that you generated.
      The path to this file is:
      $NCHOME/etc/precision/seedfile.txt
    4. In the Delimiter field, type [\t]+.
    5. Ensure that the IP Column is set to 1 and that the Name Column is set to 2.
    6. Click OK.
  6. Ensure that feedback is switched on.
    1. Click Advanced.
    2. In the Advanced Discovery Configuration section of the panel, check the setting for Enable Feedback Control.

      By default, feedback is set to Feedback only on Full, and this is the desired setting. This setting ensures that feedback is active when you are performing a full discovery, a discovery of your entire network. The entire network is made up of the managed areas that you defined using your discovery scopes.

  7. Click Save Save button to save your discovery configuration settings.

Results

Now that you have configured a more efficient discovery using the File finder, you can schedule regular discoveries to run with these settings.
