Horizontal Discovery does not detect Extra IP address in the same discovery schedulesDescriptionFor a pattern based discovery, there is no detection of duplicate IP part of discovery. This leads to additional updates for discovered CIs every day (based on the Schedule Time). Customer instances will be moved from Probes to Pattern, and there is a feature to have duplicateIPs discovered for patterns (which is not enabled by default in OOB).Steps to Reproduce Create a discovery schedule for a switch or router that has multiple IP Addresses.Add all the ip addresses to the same schedule.Switch SNMP Classification to trigger probes.Run the schedule and observer that discovery will only went through Exploration phase for 1 of the IP Addresses. The other is stopped during the Identification Phase.Switch SNMP Classification to trigger Patterns.6. Run the schedule and observe that scans for all IP Address ran to completion. No Extra/Duplicate IP Addresses detected. WorkaroundThis problem has been fixed. If you are able to upgrade, review the Fixed In section to determine the latest version with a permanent fix your instance can be upgraded to. As a workaround, set the following properties to activate extra IP Address detection for Pattern based discovery: glide.discovery.ip_based.active = falseglide.discovery.device.duplicate.ip.optimization = true NOTE: This feature is there for patterns but disabled by default.Related Problem: PRB1358510
