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
-
Click the Discovery icon and select .
- From the Domain list, select the
required domain.
- Switch off ping sweeping of your scope zones.
- Click Scope.
- For each include scope in the Scope Configuration table,
click on the Address field.
- In the Scope Properties window, uncheck the Add
to Ping Seed List option.
- Repeat this for each include scope in the Scope
Configuration table.
- Ensure that the Ping finder is still enabled.
- Click Seed.
- Check that Use Ping Finder in Discovery is
checked.
- Configure the File finder.
- Check the Use File Finder in Discovery option.
- In the File finder section of the GUI. click New
- 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
- In the Delimiter field, type [\t]+.
- Ensure that the IP Column is
set to 1 and that the Name Column is set to
2.
- Click OK.
- Ensure that feedback is switched on.
- Click Advanced.
- 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.
- Click Save 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.
