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.
