gNMI-1.17 Controller Card redundnacy test

Summary

  • collect inventory data for each controller card
  • Verify last restart time is updated

Procedure

test 1 Contyroller Card inventory

  • collect following attributes for each component of CONTROLLER_CARD type and verify corectness (mostly non-empty string)

    • /components/component/state/empty

    • /components/component/state/location

    • /components/component/state/oper-status

    • /components/component/state/switchover-ready

    • /components/component/state/redundant-role

    • /components/component/state/last-switchover-time

    • /components/component/state/last-switchover-reason/trigger

    • /components/component/state/last-switchover-reason/details

    • /components/component/state/last-reboot-time

    • /components/component/state/last-reboot-reason

    • /components/component/state/description

    • /components/component/state/hardware-version

    • /components/component/state/id

    • /components/component/state/mfg-name

    • /components/component/state/name

    • /components/component/state/parent

    • /components/component/state/part-no

    • /components/component/state/serial-no

    • /components/component/state/type

  • store list of present components of CONTROLLER_CARD type

test 2 switchover

  • Verify that all controller_cards have switchover-ready=TRUE
  • Collect and store redundant-role for each controller_card as "previous-role"
  • Initiate controller-card switchover
  • Try periodicaly (60 sec interval) untill sucesfull but no longer then 20 min: Collect redundant-role for each controller_card. Compare it with "previous-role"
    • for controller_card of current "PRIMARY" role, previous role must be "SECONDARY"
    • for controller_card of current "SECONDARY" role, previous role must be "PRIMARY"
  • try until (switchover-ready=TRUE on all controller_cards OR last-switchover-time is moret then 20min ago)
    • Wait(5min)
    • Verify that all controller_cards has switchover-ready=TRUE; if so test PASSED

test 2 Redundancy

  • Verify that all controller_cards has switchover-ready=TRUE
  • Select component with redundant-role=PRIMARY, store name as "previous_primary"
  • Perfom Controller_Card switchover and then power down "previous_primary" component. Wait 5s.
  • Collect redundant-role and oper-status from all components of CONTROLLER_CARD type as collected in test 1;
    • verify that "previous_primary" controller oper-status is not ACTIVE
    • verify that at exectly one controller_card has redundant-role=PRIMARY and oper-status=ACTIVE
    • if gNMI client can get this information, it is asumed controller card redundancy works. More torough tests of failover are part of forwarding tests.
  • Power up "previous_primary" controller card
  • Wait untill all controller_cards has switchover-ready=TRUE (cleanup)

test 3 last reboot time

  • Select component with redundant-role=SECONDARY
  • store last-reboot-time for this component as "previous-reboot-time"
  • Power down this component, wait 60 sec.
  • Power up this component
  • Wait
  • get last-reboot-time and compare with "previous-reboot-time"
    • "previous-reboot-time" must be smaller (earlier) then recently collected last-reboot-time
