configure network-clock clock-source input

configure network-clock clock-source input {[sync-e | ptp | tdm | [bits-rj45 | bits-bnc] {quality-level value}] | region [E1 | T1]}

Description

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

Syntax Description

sync-e Synchronous Ethernet (ITU-T standard) (Default).
ptp Precision Time Protocol.
tdm Time Division Multiplexing.
bits-rj45 External bits clock from RJ45.
bits-bnc External bitsw clock from BNC connector.
value Value of the quality level of the clock (T1 default QL_ST3, E1 default QL_SEC).
E1 Specifies the European and Asian clock region selection (Default).
T1 Specifies the North American clock region selection.

Default

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

Usage Guidelines

The E4G-200 and E4G-400 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.

  • TDM – an optional module which has multiple T1/E1 interfaces for TDM/Ethernet interworking.

  • BITS – Building Integrated Timing Supply. A connector capable of receiving a timing signal provided by other building equipment.

Example

The following command configures the region as T1:

configure network-clock clock-source input region t1

The following command configures the network-clock source as TDM:

configure network-clock clock-source input tdm

History

This command was first available in ExtremeXOS 15.1.

Platform Availability

This command is available on X460-24x, X460-48x E4G-200 and E4G-400 switches. On X460 platforms only Sync-E option is available as clock-source.
