Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Overview

You activate the jobs in the network modules to establish a Shell connection to host machines. Discovery tries to connect to the remote machine through the SSH, Telnet, and NTCMD protocols, until the first valid connection is found.

The module includes the following jobs:

Host Connection by Shell. Establishes the connection to remote machines through the SSH, Telnet, NTCMD, and Universal Discovery protocols. This job discovers host type, OS information, and network connectivity information. For details, see How to Discover Host Connection by Shell.
Host Connection by SNMP. Discovers SNMP agents by trying to connect, using the SNMP protocol, to a data center machine (whose IP addresses have previously been discovered and populated in IpAddress CIs in UCMDB). It then updates the correct host class (Windows, UNIX, router, and so on) according to the relevant OID. For details, see How to Discover Host Connection by SNMP.
Host Connection by WMI. Establishes the connection to remote machines through the WMI protocol and discovers host type, OS information, and network connectivity information. For details, see How to Discover Host Connection by WMI.
Client Connection by SNMP. Discovers SNMP agents by running a ping sweep of all client ranges configured in the Data Flow Probe (or Management Zone). If successful, it connects to the IP address using the SNMP protocol, and updates the correct host class (Windows, UNIX, router, and so on) according to the relevant OID. For details, see How to Discover Client Connection by SNMP.

For details on using a wizard to discover the network, see Infrastructure Discovery Activity.
