Time Sync Configuration
Overview
Use this tab to synchronize the ports by using time synchronization (based on
Precision Time Protocol [PTP]). PTP synchronizes within 25-nanosecond
accuracy the real-time clocks of the devices in a network. Using the best master
clock algorithm, the switch identifies the switch port that is connected to a device
with the best clock source. The switch then synchronizes its internal clock with
the best clock source, and that port is set to master state. The most precise clock
source in the network is referred to as the Grandmaster clock.
TIP
The information displayed here is visible when Time Sync is not
enabled. When Time Sync is enabled (checkbox checked), you see the
following fields:
• Time Sync State
• Enable Time Sync Fowarding of Time Synchronization Data
