gNMI-1.22: Controller card port attributes

Summary

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

1. 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.

Testbed type

• Single DUT

Testbed prerequisites

There are no DUT configuration pre-requisites for this test. The DUT must contain the following component types: 2 CONTROLLER_CARD components Each CONTROLLER_CARD contains at least one PORT

Procedure

• gNMI-1.22: Validate component PORT attributes attached to a CONTROLLER_CARD
  • gNMI Subscribe to the /components and /interfaces tree using ONCE option.
  • Verify each PORT present on a CONTROLLER_CARD has the following paths set:
    • Search the components to to find components of type PORT with parent = CONTROLLER_CARD
      • /components/component/state/parent = the appropriate component of type CONTROLLER_CARD
    • Search the /interfaces/interface/state/hardware-port values to find the expected /components/component/name for the physical port on the CONTROLLER_CARD
      • For each of these interfaces, verify /interfaces/interface/state/cpu = TRUE

OpenConfig Path and RPC Coverage

The below yaml defines the OC paths and RPC intended to be covered by this test.

paths:
  ## State Paths ##
    /components/component/state/name:
        platform_type: [
            "CONTROLLER_CARD",
            "PORT"
        ]
    /components/component/state/type:
        platform_type: [
            "CONTROLLER_CARD",
            "PORT"
        ]
    /interfaces/interface/state/name:
    /interfaces/interface/state/cpu:
    /interfaces/interface/state/hardware-port:

rpcs:
    gnmi:
        gNMI.Subscribe:
            ONCE: true

Minimum DUT platform requirement

MFF - Modular form factor is specified to ensure coverage for redundant CONTROLLER_CARD platform_types.
