Core fields

You use five fields which are referred to as core fields to specify a discovery filter. The five core fields are identified in Core fields of a discovery filter.

When a candidate system’s IP address matches an IP address of a discovery filter, the IP Manager uses the candidate system’s IP address and the default values of the following options to poll the candidate system:

• SNMP port number (161 by default)

• SNMP version (AUTODETECT by default)

• Access mode (ICMPSNMP by default)

• Read community string (public by default)

  These options are described in the IP Manager Reference Guide. The polling of a candidate system is shown in GUID-69F98B95-599F-48CE-BC2A-EC8301721415.html#GUID-69F98B95-599F-48CE-BC2A-EC8301721415___IP_CONCEPTS_DISCOVERY_38232.
