gNMI-1.21: Integrated Circuit Hardware Resource Utilization Test

Summary

Test used-threshold-upper configuration and telemetry for hardware resources.

Procedure

  • Connect ATE port-1 to DUT port-1, and ATE port-2 to DUT port-2.

  • Establish BGP session between ATE Port1 --- DUT Port1.

  • Get initial utilization percentages (free/(used+free) * 100) for the FIB resource in the system.

  • Configure DUT used-threshold-upper to 60% and used-threshold-upper-clear to 50%.

    • The configuration must be done at the system level such that the percentages are reflected in all components using the resource.
  • Inject unique BGP routes such that FIB utilization increases by at-least 1% (250000 routes should increase utilization by at-least 1% for Arista/Cisco/Juniper/Nokia).

  • Get utilization percentages again and validate increase in utilization.

  • Teardown BGP session such that routes are removed from FIB.

  • Get utilization percentages again and validate decrease in utilization.
