Worked on the sonic-net/sonic-mgmt repository, delivering features and stability improvements across network testing and security. Developed an API for retrieving testbed console information, enhancing test automation and debugging workflows using Python and framework development skills. Implemented firewall configuration with iptables to restrict BGP traffic on management interfaces, strengthening network security. Addressed test flakiness by refining NTP service validation and improving log analysis for multi-ASIC and DSCP mapping tests, reducing false positives and maintenance overhead. Focused on quality assurance and robust test automation, consistently validating changes on complex topologies to improve CI reliability and accelerate validation cycles for network protocols.

Jun 1, 2026June 2026: DSCP Mapping Tests Stability Fix during Warm-Reboot in sonic-mgmt. Fixed test_qos_dscp_mapping failures caused by Loganalyzer false positives and a memory-utilization alarm during warm-reboot. Implemented targeted changes (ignore_loganalyzer in reboot() to suppress benign warm-reboot log messages and pytest.mark.disable_memory_utilization to avoid transient post-reboot memory spikes). Validated on Cisco-8000 topology with Uniform mode passing and appropriate pipe-mode behavior. This work improves CI reliability, reduces flaky test churn, and strengthens QoS mapping validation in warm-reboot scenarios. Ready for backport where applicable and aligned with existing 2025.11 backport plans.

Feb 1, 2026February 2026 monthly summary for sonic-mgmt: Focused on stabilizing multi-ASIC test infrastructure and improving test reliability, with notable impacts on CI stability and platform readiness. Key fixes include loganalyzer teardown stability in multi-ASIC static route tests and ethernet test port handling, alongside safeguards to suppress expected transient routeCheck errors during config rollback while preserving FRR config and CONFIG_DB validations. A revert of an initial loganalyzer teardown adjustment was performed after re-evaluation to ensure correctness. These efforts reduced false test failures, accelerated validation cycles, and improved confidence in routing convergence behavior across multi-ASIC platforms.
