What is cwnAtmSourceBestClockSource?

This read-only TruthValue indicates whether this entry is the best clock source currently being advertised. An admin uses this flag, together with cwnRootClockSource, to identify which specific configured source in cwnAtmSourceTable is acting as the actual root of the clock distribution tree for this device or network segment. Only one entry per relevant scope should show true here, so an admin seeing multiple sources marked true unexpectedly would suspect an NCDP inconsistency.

Examples
