Introduction
This document provides PTP configuration examples.
Prerequisites
This document is not restricted to specific software or hardware versions.
The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.
This document assumes that you have basic knowledge of PTP.
Example: Configuring Layer 2 IEEE 1588v2 PTP
Network configuration
As shown in Figure 1, a PTP domain contains Device A, Device B, and Device C. Configure Layer 2 IEEE 1588v2 PTP as follows for time synchronization:
· Specify the IEEE 1588v2 PTP profile for the devices.
· Specify the OC clock node type for Device A and Device C, and E2ETC clock node type for Device B. These clock nodes elect a GM through BMC based on their respective default GM attributes.

Network configuration
As shown in Figure 3, configure PTP (IEEE 1588 version 2, IPv4 UDP transport, unicast transmission) to enable Device A, Device B, Device C, and the base station to synchronize the time with the ToD clock source.
· Specify the IEEE 1588 version 2 PTP profile and unicast IPv4 UDP transport of PTP messages for Device A, Device B, and Device C.
· Assign Device A, Device B, Device C, and the base station to PTP domain 0. Specify the BC clock node type for Device A, Device B, and Device C.
· Connect Device A to the ToD clock source and Device C to the base station.
· Use the default Request_Response delay measurement mechanism on all clock nodes in the PTP domain.

Network configuration
As shown in Figure 4, a PTP domain contains Device A, Device B, and Device C. Configure IEEE 802.1AS PTP as follows for time synchronization:
· Specify the IEEE 802.1AS PTP profile for the devices.
· Specify the OC clock node type for Device A and Device C, and the P2PTC clock node type for Device B. These clock nodes elect a GM through BMC based on their respective default GM attributes.

Network configuration
As shown in Figure 6, configure PTP (SMPTE ST 2059-2, IPv4 UDP transport, unicast transmission) to enable Device A, Device B, Device C, and the base station to synchronize time with the ToD clock source.
· Specify the SMPTE ST 2059-2 PTP profile and unicast IPv4 UDP transport of PTP messages for Device A, Device B, and Device C.
· Assign Device A, Device B, Device C, and the base station to PTP domain 0. Specify the BC clock node type for Device A, Device B, and Device C.
· Connect Device A to the ToD clock source and Device C to the base station.
· Use the default Request_Response delay measurement mechanism on all clock nodes in the PTP domain.

Restrictions and guidelines
The switch does not provide a ToD interface. You cannot use it as Device A, but can use it as Device B or C.
Procedure
|
|
IMPORTANT: The SMPTE ST 2059-2 PTP profile supports IPv4 UDP transport rather than IEEE 802.3/Ethernet transport of PTP messages. It supports both multicast and unicast transmission of PTP messages. |
|
|
IMPORTANT: · In Release 655x and Release 6607, for PTP to run on an interface, you only need to enable PTP on the interface. · In Release 6616, Release 6616P01, and Release 6635 and later, for PTP to run on an interface, you must enable PTP globally and on the interface. |

Configuring the base station.
# Specify PTP domain 0.
# Specify IPv4 UDP transport of PTP messages.
# Set the destination IP address of unicast PTP messages to 12.10.10.2.
# Specify the Request_Response delay measurement mechanism.
For more information, see the configuration guide for the base station.
Verifying the configuration
|
|
IMPORTANT: Only in Release 6616, Release 6616P01, and Release 6635 and later, the device supports PTP multiple instances and the InstID field is displayed in the output of the display ptp interface brief command. |
When the network is stable, perform the following tasks to verify the PTP configuration:
· Use the display ptp clock command to display PTP clock information.
· Use the display ptp interface brief command to display brief PTP running information.
