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

• https://github.com/openconfig/featureprofiles/blob/main/topologies/atedut_2.testbed

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
