Configuring connections to known devices
Netcool/Precision TN allows you to specify a set of devices with which to connect; this
information is held in a plain text hosts file.

This feature allows you to bypass both the Network Pilot manual creation process and the
automatic discovery mechanism when the set of devices in the network are known to you.

Netcool/Precision TN automatically creates the Network Elements (NEs) listed in the hosts
file if they do not already exist. The NE creation is a controlled and configurable process by
which Netcool/Precision TN can cumulatively add new NEs, or delete ones no longer listed
in the hosts file.

Packaging and configuration
This feature is part of the discovery framework, and provides the ability to schedule the
task at specified times.

A single host file is defined by the discovery schedule, listing the set of devices to which
Netcool/Precision TN will connect.
Netcool/Precision TN will connect.
This feature is enabled by default. Disable the feature by adding the following lines to the
precisiontn.xml
precisiontn.xml
file:
<properties name="LEAPFramework">
<property name="lumos.leap.service.discovery.filedriven.Enabled"
value="false" />
</properties>
The hosts-based connectivity can be configured to cumulatively create all the NEs across
different runs of the discovery task, or to delete NEs removed from the hosts file. Add the
following lines to the precisiontn.xml file if you want to cumulatively add NEs (replace
the “false” value with “true” to remove them):
