For March 2026, sonic-net/sonic-utilities delivered a significantly enhanced network diagnostics capability by introducing a Network Interface Diagnostics CLI that surfaces PHY signal and SERDES attributes per interface. The feature adds CLI commands show interfaces <intf> <phy-signal/phy-serdes> with two subcommands for quick health checks and deeper metrics. The work, anchored by commit d09d6cd67a397a52524d56ffbee9ce6abf868f0f (PR #4312), includes added tests, minor command refinements, and fixes to interface alias display names and DB connections. A bug fix ensures show interface outputs are produced correctly even when the database has no data. Overall, this delivers faster troubleshooting, richer diagnostics, and improved operator experience across the SONiC utilities suite.

November 2025 monthly summary focused on stabilizing sonic-mgmt container checker tests by fixing Monit-driven configuration updates and ensuring proper Monit startup sequencing. The work emphasizes reliability, faster feedback, and maintainability of the test infra.
