configure network-clock clock-source input

configure network-clock clock-source input {[sync-e | ptp |region [E1 | T1]}


Configure the input network clock source as Sync-E or PTP. A region can also be configured using this command.

Syntax Description

sync-e Synchronous Ethernet (ITU-T standard) (Default).
ptp Precision Time Protocol.
E1 Specifies the European and Asian clock region selection (Default).
T1 Specifies the North American clock region selection.


The default input clock source is Synchronous Ethernet. The default region is E1.

Usage Guidelines

The ExtremeSwitching X460-G2 series switches have clock sources beyond SyncE. The clock which drives all of the ports on a switch may be selected from:
  • SyncE (Synchronous Ethernet).
  • PTP – Precision Time Protocol, an optional 1588v2 module.


The following command configures the region as T1:

# configure network-clock clock-source input region t1


This command was first available in ExtremeXOS 15.1.

Platform Availability

This command is available on the ExtremeSwitching X460-G2 series switches.
