IBM 5.5 manual Configuring connections to known devices, Packaging and configuration, Syntax

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.

This feature is enabled by default. Disable the feature by adding the following lines to the 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):

<properties name="LEAPFramework">

<property name="lumos.leap.service.discovery.filedriven. DeleteMissingNE" value="false" />

</properties>

Syntax

The hosts file can reside anywhere in the file system. It is a plain text file with comma separated positional fields.

A comment line starts with “//”. Each line in the file represents an NE with which to connect. The format of each line is as follows:
