gNMI-1.18: gNMI subscribe with sample mode for backplane capacity counters

Summary

WBB is required to support gNMI Subscribe with SAMPLE or ON_CHANGE mode for various counters. This test if to verify that DUT supports gNMI Subscribe with ON_CHANGE for backplane-facing-capacity

Testbed type

Procedure

gNMI-1.18.1

  • Connect DUT port-1 and 2 to ATE port-1 and 2 respectively

    • For MFF DUT ports 1 and 2 SHOULD be on different linecards

  • Configure IPv4/IPv6 addresses on the interfaces

  • Using gNMI subscribe with "ON_CHANGE" mode

    • /components/component/integrated-circuit/backplane-facing-capacity/state/consumed-capacity

      • consumed-capacity is the sum of the admin-up front panel interface speeds connected to the integrated-circuit

  • Ensure that we receieve the initial consumed-capacity metric

  • Set port-2 enabled=false

    • Validate that we recieve a changed consumed-capacity metric of a higher value

  • Set port-2 enable=true

    • Validate that we recieve a changed consumed-capacity metric matching the initial value

gNMI-1.18.2

  • Use gNMI subscribe with "ON_CHANGE" mode for the below telemetry paths

    • /components/component/integrated-circuit/backplane-facing-capacity/state/total
    • /components/component/integrated-circuit/backplane-facing-capacity/state/total-operational-capacity
    • /components/component/integrated-circuit/backplane-facing-capacity/state/available-pct

  • Make sure we recieve the initial metric for each of the telemetry paths

  • Disable two FABRIC components

    • set /components/component/{fabric}/config/power-admin-state to POWER_DISABLED

  • Validate that we recieve changed metric of a lower value for the below telemetry paths

    • /components/component/integrated-circuit/backplane-facing-capacity/state/total-operational-capacity
    • /components/component/integrated-circuit/backplane-facing-capacity/state/available-pct

  • Ensure that the metric for the below telemetry path should not have changed hence no updated metric should be received

    • /components/component/integrated-circuit/backplane-facing-capacity/state/total

  • Enable the FABRIC components that were disabled previously

    • Set /components/component/{fabric}/config/power-admin-state to POWER_ENABLED

  • Validate that we recieve changed metric matching the initial metric for the below of the telemetry paths

    • /components/component/integrated-circuit/backplane-facing-capacity/state/total-operational-capacity
    • /components/component/integrated-circuit/backplane-facing-capacity/state/available-pct

  • Ensure that the metric for the below telemetry path should not have changed hence no updated metric should be received

    • /components/component/integrated-circuit/backplane-facing-capacity/state/total
