Validate PORT components attached to a CONTROLLER_CARD are modeled with the expected OC paths. The operational use case is:

As an automated network repair tool, I want to ensure at least one interface between redundant CONTROLLER_CARD components is fully operational. Before performing a power off or reboot of a CONTROLLER_CARD or a network device wired to a CONTROLLER_CARD PORT, I want to use the OC component tree to trace the subject PORT to it's associated redundant PORT.

• Single DUT

There are no DUT configuration pre-requisites for this test. The DUT must contain the following component types:

• Two CONTROLLER_CARD components
• Each CONTROLLER_CARD must contain at least one PORT

• gNMI Subscribe to the /components and /interfaces tree using ONCE option.
• Verify two CONTROLLER_CARD components are present.
• Verify each PORT present on a CONTROLLER_CARD has the following paths set:
  • Find components of type PORT with parent = CONTROLLER_CARD. For example:
    • /components/component/state/parent = the appropriate component of type CONTROLLER_CARD
    • Save the /components/component/name for each of the identified PORTs.
  • Search the /interfaces/interface/state/hardware-port values to find the port names for the physical port on the CONTROLLER_CARD
    • For each of these interfaces, verify /interfaces/interface/state/management = TRUE
