May 2025 delivered two high-value features with robust test coverage, improving observability and config flexibility. ICMP_ECHO_SESSION support was added end-to-end in sonic-sairedis (meta, syncd, and notification paths) with unit tests validating notifications and attribute handling. The MUX_CABLE YANG model gained a prober_type field to configure hardware/software probing, defaulting to software, enabling DualToR LinkMrgrd Icmp Prober workflows. No explicit bug fixes were reported in this period; the focus remained on feature delivery and test coverage, strengthening business value through improved monitoring, configurability, and deployment flexibility.

Month 2024-11 highlights: Stability and reliability improvements to the sonic-mgmt test suite for SNMP telemetry on multi-ASIC platforms. Delivered fixes that address test flakiness, a KeyError in multi-ASIC buffer queue deletion, and timing issues to ensure commands run only after interfaces come up. The work strengthens CI confidence, accelerates validation of multi-ASIC deployments, and reduces debugging time for platform issues. Key deliverables were implemented in a focused commit addressing test_snmp_queue_counters.py and related telemetry tests, enabling more predictable test outcomes and smoother onboarding of new platforms.
