Explains Precision Time Protocol configuration and setup, including Network Time Protocol to Precision Time Protocol conversion and serviceability features for network switches.
Precision time protocol
Describes a time synchronization protocol designed for packet-based networks with distributed device clocks.
NTP to PTP time conversion
Describes a feature that allows you to use Network Time Protocol (NTP) as a time source for PTP, enabling customers to correlate data between PTP networks and enterprise data centers running NTP.
Requirements for NTP to PTP conversion
Outlines the prerequisites for using the NTP to PTP conversion feature on the switch.
PTP configuration and mode limitations
Consider these guidelines and limitations when configuring PTP messages, modes, packet formats, VLANs, clocks, and feature interactions.
Default settings
Lists the default PTP configuration settings for the switch.
PTP switch configuration
Describes the procedures for configuring Precision Time Protocol (PTP) on network switches.
Configure NTP to PTP time conversion
Configure NTP to PTP time conversion to enable the switch to use Network Time Protocol as a time source for Precision Time Protocol synchronization.
PTP serviceability
Describes the ability to troubleshoot and monitor PTP performance on a network with a Cisco IE Switch.
