Configure ptp-1588 timing for circuit pack

Procedure 8-1.2: Configure ptp-1588 timing for circuit pack

Overview

Use this procedure to provision ptp-1588 timing for a VLNC6x circuit pack.

The IEEE 1588 protocol distributes time and frequency via Ethernet with expected endpoint time-alignment time precision measured in nanoseconds. The protocol is designed to synchronize real-time clocks on the nodes of a distributed system that communicate using a network.

The protocol uses a master/slave relationship to distribute timestamps from one device to the others. The protocol traffic is an Ethernet frame with a special Ethertype field to indicate 1588.

Step


1	From the Navigation menu, select Timing → System Timing → Configuration. Result: The System Timing Configuration screen appears.
2	Important! The System Timing Source parameter must be provisioned to ptp-1588 for 1588ver2 Precision Timing Protocol timing. Enter the required System Timing Source and Differential Timestamp Frequency parameters, then click Submit.
3	From the Navigation menu, select Timing → System Timing → Summary and verify that the system timing parameters were provisioned correctly. Result: The System Timing Summary screen appears.
4	From the Navigation menu, select Timing → ptp-1588 Timing → ptp-1588 Protocol Configuration. Result: The ptp-1588 Protocol Configuration screen appears.
5	Enter the required parameters, then click Submit. Parameters include: State: Enables or disables the IEEE 1588 Precision Timing Protocol on the system. Mode: Enables/disables the master or slave mode. VLAN ID: Specifies the VLAN id over which the 1588 protocols are transmitted. Primary Port: Specifies the primary port over which the 1588 protocols are transmitted and received. Backup Port: Specifies the backup port over which the 1588 protocols are transmitted and received. Priority1: Specifies the priority1 of the 1588 protocol. It is used only in the Master mode while sending the 1588 protocol message. Priority2: Specifies the priority2 of the 1588 protocol. It is used only in the Master mode while sending the 1588 protocol message. Domain: Specifies the PTP domain value of the 1588 protocol. Log Mean Sync Interval: Specifies the Log Mean Sync Interval of the 1588 protocol. Log Min Mean Delay Interval: Specifies the Log Minimum Mean Delay Interval of the 1588 protocol. Log Mean Announce Interval: Specifies the Log Mean Announce Interval of the 1588 protocol. Announce Receipt Timeout: Specifies the Announce Receipt Timeout Interval of the 1588 protocol. Time Switch Mode: Specifies the switch over of master clock selection is controlled by 1588 protocol’s master clock selection algorithm or by the system. Multicast MAC Address: Specifies the Multicast MAC address on which to send/receive the 1588 protocol messages.
6	From the Navigation menu, select Timing → ptp-1588 Timing → ptp-1588 Protocol Summary and verify that the required parameters were provisioned correctly. Result: The ptp-1588 Protocol Summary screen appears. End of steps
