PTP (Precision Time Protocol) configuration manages IEEE 1588v2 clock synchronization on NX-OS devices. Settings include global clock properties (domain, priority, device type, source IP), convergence tuning, correction range thresholds, delay tolerance, multi-domain support, notifications, and per-interface PTP parameters (intervals, transport, transmission mode, role, unicast peers). The global ttag marker interval used for PTP-based latency measurement (ttag-marker-interval) is configured under system.
