Modelinggateway import does not model a device whose network_address is already present in the DeviceIPAddressList of a device already discovered and modeled in the ssdb.
the above device has IP Network_Addess = 10.35.60.253 and a Vlan interface with IP 10.183.1.35
If you try to import via modelinggateway a device with IP = 10.183.1.35 (same of vlan interface) it will not be created because the IP 10.183.1.35 also appears in the DeviceIPAddressList of device Sim36432...
The DeviceIPAddressList is a table that contains an Instance =
Release : 20.2.x, 21.2.x
Component : Spectrum Core / SpectroSERVER
This is FAD for the current Spectrum versions.
Engineering team are thinking to add an option "IgnoreAssociatedDeviceIPAddress" in .modelinggatewayresource.xml file in the "ImportConfiguration" section . When set to true it allows modeling gateway device creation even if the concerned IP is associated with another device . The only exception is that new model device creation fails if the concerned IP address is used as Network_address of another device .
This new functionality will be included in the next Spectrum release (probably 21.2.7).
