TRANSCEIVER-7: Telemetry: 400ZR Optics inventory info streaming

Summary

Validate 400ZR modules report correct inventory information.

Procedure

  • Plug in the ZR module in the host port and make sure the transceiver state is enabled and host is able to detect the module.

  • With the module recognized verify it reports correct inventory information by subscribing ON_CHANGE to the following telemetry paths.

    • /platform/components/component/state/serial-no
    • /platform/components/component/state/part-no
    • /platform/components/component/state/type
    • /platform/components/component/state/description
    • /platform/components/component/state/mfg-name
    • /platform/components/component/state/mfg-date
    • /platform/components/component/state/hardware-version
    • /platform/components/component/state/firmware-version

  • Validate the streamed inventory information data is of type String.

  • Verify that the modules inventory information is reported correctly after an optic software reset.

    • With ZR module plugged in the host and properly recognized
    • Verify the ZR optics inventory is correctly reported via the streaming telemetry paths above.
    • Reset the optic by enabling and disabling the transceiver state through /components/component/transceiver/config/enabled.
    • Wait at least 20 seconds in between toggling transceiver state.
    • Verify the ZR optics still reports correct inventory information.
    • Telemetry subscription should be ON_CHANGE and streamed data should be of type String.

  • Verify that the modules inventory information is reported correctly when interface state is disabled.

    • With ZR module plugged in the host and properly recognized
    • Use /interfaces/interface/config/enabled to disable the module interface state, wait 20 seconds.
    • Verify the ZR optics inventory information is correctly reported via the streaming telemetry paths above in this state.
    • Telemetry subscription should be ON_CHANGE and streamed data should be of type String.

  • Verify the module behaviour and related inventory information when transceiver state is set to disabled.

    • With ZR module plugged in the host and properly recognized.
    • Use /components/component/transceiver/config/enabled to disable the module transceiver state, wait 20 seconds.
    • Verify the ZR module is powered off and no inventory information reported via the streaming telemetry paths above in this state.
    • When a component is powered off and is dropped from the inventory list explicit deletes for the relevant entity leaves should be streamed to clear any stale data.
    • Telemetry subscription should be ON_CHANGE and there should be no streamed inventory data in this state.

  • Verify the module inventory information updates when transceiver under test is swapped with a different one.

    • Make sure ZR module plugged in the host and properly recognized.
    • Verify module is reporting valid inventory information.
    • Swap the module with a different one and validate that the new inventory information is correctly streamed now.
    • Telemetry subscription should be ON_CHANGE and streamed data should be of type String.
