Virtual Parameters Device IP Interface

Hello, i want to ask about Virtual Parameters.

List Device IP Interface Parameters sample 1-10 it may be more, every parameters have value

Device.IP.Interface.1.IPv4Address.1.IPAddress
Device.IP.Interface.2.IPv4Address.1.IPAddress
Device.IP.Interface.3.IPv4Address.1.IPAddress
Device.IP.Interface.4.IPv4Address.1.IPAddress
Device.IP.Interface.5.IPv4Address.1.IPAddress
Device.IP.Interface.6.IPv4Address.1.IPAddress
Device.IP.Interface.7.IPv4Address.1.IPAddress
Device.IP.Interface.8.IPv4Address.1.IPAddress
Device.IP.Interface.8.IPv4Address.2.IPAddress
Device.IP.Interface.9.IPv4Address.1.IPAddress
Device.IP.Interface.10.IPv4Address.1.IPAddress

Every device have random parameter Device.IP.Interface.*

How to do it?, virtual parameter displays who has value “10.150.x.x” or “10.170.x.x”.
I want to show this parameter at index page.

- label: "'IP OAM'"
  parameter: Device.IP.Interface.3.IPv4Address.1.IPAddress

sometimes it’s in the parameters Device.IP.Interface.3.IPv4Address.1.IPAddress or Interface.1
inconsistent parameters for put at index page
