To configure the IEEE 1588 PTP clock on a 7210 SAS, 7250 IXR, 7450 ESS, or 7750 SR

Purpose

Perform this procedure to configure the IEEE 1588 PTP clock on a device that is configured as an IEEE 1588 PTP client. See To configure timing synchronization for information about how to configure a device as a PTP client.

Depending on the PTP profile you are configuring, you may need to configure PTP peers or PTP ports; see To configure the IEEE 1588 PTP peer of a 7210 SAS, 7250 IXR, 7450 ESS, or 7750 SR and To configure IEEE 1588 PTP ports on a 7210 SAS, 7250 IXR, 7450 ESS, 7750 SR, or 7950 XRS.

Steps
 
1 

In the navigation tree equipment view, right-click on the required device and choose Properties. The Network Element (Edit) form opens.

2 

Click on the IEEE PTP Clock tab.

3 

Select an IEEE 1588 PTP Clock from the list and click Properties. The IEEE 1588 PTP Clock (Edit) form opens.

4 

Configure the required parameters.

At least one IEEE PTP peer or port must be created before you can set the Admin State parameter to Enabled. See To configure the IEEE 1588 PTP peer of a 7210 SAS, 7250 IXR, 7450 ESS, or 7750 SR and To configure IEEE 1588 PTP ports on a 7210 SAS, 7250 IXR, 7450 ESS, 7750 SR, or 7950 XRS.

When the Admin State parameter is set to Enabled, you cannot change the following parameters:

  • Clock Type

  • PTP Profile

  • Domain

  • Clock Announce Rx Timeout

  • Clock Announce Interval

  • Log sync interval

The PTSF Unusable Admin State parameter is only configurable when the PTP Profile is set to ITU-T G.8275.1.

For the 7210 SAS-D ETR, 7210 SAS-K, 7210 SAS-M, 7210 SAS-R, 7210 SAS-S/Sx VC, 7210 SAS-T, 7210 SAS-T ETR, and 7210 SAS-X: when the Clock Type parameter is set to Boundary, you must set the PTP Profile parameter to IEEE-1588-2008.

If you are configuring an ITU-T G.8275.1 profile on a supporting 7210 SAS NE, you must choose Boundary Clock for the Clock Type parameter and ITU-T G.8275.1 for the PTP Profile parameter.

If you are configuring an ITU-T G.8275.1 profile on a 7250 IXR, you must choose Boundary or Slave for the Clock Type parameter and ITU-T G.8275.1 for the PTP Profile parameter.

The ITU-T G.8265.1 profile only supports master slave clocks and PTP peers. For the 7250 IXR-e big/small, the ITU-T G.8265.1 profile only supports ordinary slave clocks and PTP peers.

Changes to the PTP Profile and Frequency Source parameters may require an NE reboot to take effect; see the NE documentation for more information. The currently effective frequency source is displayed as the Oper Frequency Source.

To make SSU the effective Oper Frequency Source, the timing reference must be qualified and the Status must be set to Master Locked on the Timing tab of the shelf properties form; see To configure timing synchronization. Also, the Admin State parameter on the General tab of the ptp clock tab must be set to enabled.

Note: The displayed parameters vary depending on the NE type, release, and the settings of other parameters.
