Loopback adapters are removed from the network adapter table as they do not have a MAC addresses - Known Error

Loopback adapters are removed from the network adapter table as they do not have a MAC addresses Description Previously, PRB1646016 removed interfaces with no MAC address. However, this eliminated loopback interfaces from discovery.

In the pattern, SNMP Identity, reverted the change in the step "Remove empty MAC or name from Network Adapter" (from PRB1646016 ) where the filtering condition for cmdb_ci_ni_interface was All for name and mac_adress fidels. In other words, the condition is set back to "Any", And then removed the interfaces with no MAC from dscy_router_interface after the step "Insert network adapters data to dscy_router_interface" as IRE does not permit dscy_router_interface records with null value for the MAC address field.

Steps to Reproduce

Run discovery of network router with loopback interfaces Observe loopback interface network adapter records are removed Workaround This problem has been fixed. If an upgrade is possible, please upgrade to ITOM Visibility Content May 2024 release or later.
