FlexE Time Synchronization Modes
As shown in Figure 1, the FlexE standards define two 1588v2 message transmission modes: OH and Client. By default, 1588v2 messages are transmitted in OH mode.
- OH mode: Clock messages are transmitted using FlexE overhead timeslots. The configuration related to clock synchronization is the same as the configuration on a standard Ethernet interface.
- Client mode: Clock messages are transmitted using FlexE clients. In this mode, the FlexE interface that carries clock services must be bound to a FlexE physical interface that has clock services deployed.
The time synchronization modes at the two ends of a FlexE link must be the same (either the OH or Client mode).
