  • TE-11.2, TE-11.21: reduce traffic rate to 10k pps for SRL containers.
  • TE-2.1: add WaitForARP after StartProtocols in createTrafficFlows.
  • TE-3.5: use gnmi.Watch/Await for AFT ipv4-entry telemetry checks.

Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces several stability and reliability improvements for gRIBI tests running on KNE. The changes primarily focus on adjusting traffic parameters, ensuring proper ARP resolution before traffic flow, and enhancing telemetry verification mechanisms to handle asynchronous state updates more effectively.

Highlights

  • Traffic Rate Adjustment: Reduced the traffic rate to 10k pps for SRL containers in multiple test files to improve stability on KNE.
  • ARP Resolution: Added WaitForARP calls after protocol startup in createTrafficFlows to ensure network readiness.
  • Telemetry Verification: Updated AFT IPv4-entry telemetry checks to use gnmi.Watch/Await for more robust state validation.

Code Review

This pull request reduces the traffic frames per second (fps) in backup NHG tests, adds mandatory WaitForARP calls in ipv4_entry_test.go to ensure neighbor resolution, and replaces static gnmi.Get calls with gnmi.Watch in ordering_ack_test.go to monitor IPv4 entry states. The reviewer recommended replacing the hardcoded time.Minute timeout in the new gnmi.Watch calls with the package-level awaitDuration constant to prevent test flakiness in slow virtual environments.
