gNOI-5.1: Ping Test

Summary

Validate ping request and response work on the device, with parameters covering VRF, source-IP address and different packet sizes. L3 Protocol used will be ICMP, which is default.

Topology

• DUT
  • Note: The current test only pings its looplack address to exercise the gNOI API. The test may require the use of ATE for new tests in future.

Procedure

• Issue gnoi.system Ping command. Provide following parameters:
  • Destination: populate this field with the
    • target device loopback IP address
    • TODO: an IP-in-IP tunnel-end-point address
    • TODO: an address matching regular non-default route
    • TODO: an address matching the default route
    • TODO: an address requiring VRF fallback lookup into default vrf
    • TODO: supervisor's physical management port address
    • TODO: floating management address
  • Source: populate this field with
    • loopback IP address
    • regular interface address
    • TODO: an IP-in-IP tunnel-end-point address
    • TODO: supervisor's physical management port address
    • TODO: floating management address
  • VRF:
    • TODO: Set the VRF to be management VRF, TE VRF and default fallback VRF
  • Size:
    • Set to min packet size of 64, ethernet packet size of 1512, max mtu of jumbo frame 9202, and value slightly bigger than the egress interface MTU of a transit router to test do_not_fragment.
    • TODO: verify these for vlan tagged vs untagged packets. May need +4 bytes
