Validate interfaces counters including both IPv4 and IPv6 counters.

In the automated ondatra test, verify the presence of the telemetry paths of the following features:

• Configure Interface and add load-interval:

  • /interfaces/interface/rates/config/load-interval

• Configure IPv4 and IPv6 addresses under subinterface:

  • /interfaces/interface/config/enabled
  • /interfaces/interface/subinterfaces/subinterface/config/enabled
  • /interfaces/interface/subinterfaces/subinterface/ipv4/config/enabled
  • /interfaces/interface/subinterfaces/subinterface/ipv6/config/enabled

  Validate that IPv4 and IPv6 addresses are enabled:

  • /interfaces/interface/subinterfaces/subinterface/ipv4/addresses/address/state/enabled
  • /interfaces/interface/subinterfaces/subinterface/ipv6/addresses/address/state/enabled

• Validate that Interface has load-interval configured:

  • /interfaces/interface/rates/state/load-interval

• Validate if counters are being updated consistently

  Check the presence of packet counter paths and monitor counters every 30 seconds. Generate traffic to get atleast 10 or more samples.

The test uses a 2 port ATE setup where 2 ports are used as a singleton interface Ports are configured with ipv4, ipv6 interfaces on DUT and ATE. Traffic is sent and from ATE to DUT and the counters are verified.

The below yaml defines the OC paths intended to be covered by this test. OC paths used for test setup are not listed here.
