Configuring PTP
Precision Time Protocol (PTP) is defined in IEEE 1588 as Precision Clock Synchronization for Networked Measurements
and Control Systems, and was developed to synchronize the clocks in packet-based networks that include distributed
device clocks of varying precision and stability. PTP is designed specifically for industrial, networked measurement and
control systems, and is optimal for use in distributed systems because it requires minimal bandwidth and little processing
overhead.
For information about configuring PTP on Cisco Industrial Ethernet switches, see Precision Time Protocol Software
Configuration Guide for IE 4000, IE 4010 and IE 5000 Switches.
