(Optional) Configuring a Time Synchronization Mode for a FlexE Physical Interface

The FlexE standards define two 1588v2 message transmission modes: Overhead (OH) and Client. By default, 1588v2 messages are transmitted in OH mode.

Context

OH mode: Clock messages are transmitted using FlexE overhead timeslots. The configuration related to clock synchronization is the same as that 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.

Pre-configuration Tasks

1588v2 has been configured, no matter which mode is used to transmit 1588v2 messages. For details, see HUAWEI NetEngine 8000 F Series Router Configuration Guide > System Management.

After 1588v2 is configured on a FlexE physical interface, 1588v2 messages are transmitted in OH mode by default. To change the transmission mode of 1588v2 messages to Client, perform the following steps.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The view of a specified FlexE physical interface (for example, FlexE-50G 0/1/0) is displayed.
Run clock binding flexe interface iftype ifnum
A specified FlexE interface carrying clock services is bound to the FlexE physical interface.
Run commit
The configuration is committed.
