Configure the IP Manager for discovery

Preparing the IP Manager for discovery starts with seed systems, which serve as the starting point for both manual discovery and autodiscovery.

In addition, to support satellite Domain Managers, an administrator performs the following configuration tasks to prepare an IP Manager for discovery as listed in Configuration tasks to prepare an IP Manager for discovery .

Configuration tasks to prepare an IP Manager for discovery lists the configuration tasks to prepare an IP Manager for discovery.

Table 1. Configuration tasks to prepare an IP Manager for discovery
Configuration tasks	Applicability	Note
Enable light discovery “Enabling light discovery for satellite Domain Managers” on page 57 describes the procedure.	Satellite Domain Manager	By default, light discovery is disabled.
Set the DiscoveryAddrPref to IPV4_ADDRONLY in discovery.conf file	All satellite Domain Managers	Ensures that the SNMPAgent objects that are imported by a satellite Domain Manager from the IP Manager have only IPv4 addresses.
Specify one or more CLI device-access objects	If a satellite Domain Manager is to import CLI device-access objects from the IP Manager.	An administrator can attach the Polling and Thresholds Console directly to an IP Manager to configure CLI device-access objects.
Enable overlapping IP address discovery	If a satellite Domain Manager is to import tagged IP and IPNetwork objects from the IP Manager.	NA
Enable interoperability with the VPN-tagging server	Only if the IP Manager is enabled to perform overlapping IP address discovery.	NA

The tpmgr-param.conf file contains configuration parameters that you edit to customize IP Manager discovery. The parameters are a subset of table entries that are defined for the ICF-TopologyManager object. Use the parameters in this file to accomplish such tasks as disabling the discovery of certain interfaces or ports, enabling the discovery of topology collection sets for satellite Domain Managers, and changing the operation of the IP Manager to be backward compatible with earlier versions of satellite Domain Managers. To open and edit the tpmgr-param.conf file:

Go to the BASEDIR/smarts/bin directory in the IP Manager installation area and type the following command to open the tpmgr-param.conf file:
```
               sm_edit conf/discovery/tpmgr-param.conf
            
```
Press Enter. This opens the tpmgr-param.conf file. Make the necessary edits.

Discovery methods and the associated tasks lists the discovery methods, the scenarios when you would use it and the various tasks related to it.

Table 2. Discovery methods and the associated tasks
Discovery method	What it does...	Use it when...	Requirements	Tasks
Manual discovery	The IP Manager discovers a set of systems that are specified in a seed file, or discovers an individual system that is specified in an Add Agent command.	The topology information is available from a well-maintained database.	Seed files	“How to create a seed file” on page 96 Also, see “Seed file related tasks” on page 95
Autodiscovery	The IP Manager takes IPv4 addresses that are obtained from discovered systems to find additional discovery candidate systems.	The topology information is incomplete or unavailable, or when manual updates cannot be maintained.	Discovery filters	“How to create a discovery filter” on page 89 “How to delete a discovery filter” on page 89
