gNMI-1.16 Fabric redundnacy test
Summary
collect inventory data for each fabric card
Verify last restart time is updated
verify traffic could be forwarded with one of Fabric Card inactive.
Procedure
topology and basic setup
Connect OTG port1 to DUT port1 and OTG port2 to DUT port2
Configure IPv6 addresses on both links
test 1 Fabric inventory
collect following attributes for each component of FABRIC_CARD type and verify corectness (mostly non-empty string)
/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/oper-status
/components/component/state/parent
/components/component/state/part-no
/components/component/state/serial-no
/components/component/state/type
/components/component/state/location
/components/component/state/last-reboot-time
store list of present components of FABRIC_CARD type
test 2 redundancy
Power down exectly one component of fabric type
Run traffic between ATE por1 and port 2 for 16 millions of packets on 100kpps rate and using 4000B packets.
verify loss-lessness (with 10E-6 tolerance); Since remaining fabric is not overloaded in any form
with above traffic pattern 0 losses is expected
Power up all components
test 3 last reboot time
Select one component from list of available
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". The "PREVIOUS_REBOOT_TIME" must be smaller (earlier) then recently collected last-reboot-time
