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.

· Use the default Request-Response delay measurement mechanism for Device A and Device C.

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.

Example: Configuring IEEE 802.1AS PTP

Network configuration

As shown in Figure 1, 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 Device A, Device B, and Device C.

· Specify the OC clock node type for Device A and Device C, and P2PTC clock node type for Device B. These clock nodes elect a GM through BMC based on their respective default GM attributes.

· Use the default peer delay measurement mechanism on all clock nodes in the PTP domain.

Example: Configuring PTP (SMPTE ST 2059-2, IPv4 UDP transport, unicast transmission)

Network configuration

As shown in Figure 10, 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.

Procedures

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:

The device does not provide ToD interfaces. It can be deployed as Device B or Device C but not Device A.

‌

Before configuration, assign IP addresses to the interfaces, and make sure the devices can reach each other. (Details not shown.)

Verifying the configuration

IMPORTANT:

· The Lock status field in the output from the display ptp clock command is available only for the S6550XE-HI switch series and S6525XE-HI switch series.

· The InstID field in the output from the display ptp interface brief command is available only for the S6550XE-HI switch series and S6525XE-HI switch series.

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.
