PROFILE
Sarabjeet Singh [marvell]
Sarabjeet Singh enhanced the sonic-net/sonic-mgmt repository by expanding Marvell-Teralynx platform test coverage and improving SNMP service reliability. He developed Python-based test automation to validate NVGRE hash, VLAN tagging, and ARP handling, integrating CLI MAC metadata reading to streamline configuration and debugging. Singh also addressed SNMP test flakiness by enforcing IPv4-only addresses in management VRF contexts, updating test fixtures to align with expected configurations and reduce service restarts. His work demonstrated depth in network management, Python scripting, and platform integration, resulting in more robust, maintainable test suites and improved CI reliability for complex networking scenarios.

Mar 1, 2026In March 2026, delivered SNMP Service Reliability improvements for sonic-net/sonic-mgmt by enforcing IPv4-only addresses in mgmt-vrf contexts to fix test-case failures caused by IPv6 usage. The change updates test fixtures to remove IPv6 from DUT, aligning mgmt-vrf SNMP configuration with test expectations and preventing excessive SNMP restarts. Verified by running mvrf/test_mgmtvrf.py tests (warmboot, reboot, fastboot) all PASSED. Commit: ec524cfdac12ce3c173812387c9477c5e9ec694d. Impact: more stable SNMP service, fewer restarts, and improved CI reliability. Skills demonstrated: Python test automation, fixture development, VRF/mgmt-vrf orchestration, and IPv4-centric SNMP validation.

Feb 1, 2026February 2026: Expanded Marvell-Teralynx platform testing coverage and tooling in sonic-mgmt, enabling robust validation of NVGRE hash, VLAN/test enablement, HASH module compatibility, and ARP handling. Implemented CLI MAC metadata reading to simplify test configuration, execution, and debugging. Improved test reliability through enhanced error messaging and targeted test cases (e.g., arp_unknown_mac), with tighter integration to platform-specific test suites.
