PTP Clock Subnet

According to the actual networking situation, the network planning personnel need to divide the entire network into different clock subnets in planning the clock network. Within each subnet, time synchronization can be implemented for all clocks, to meet customer requirements. In this user interface, you can set the clock subnet to ensure that the clocks in the same clock subnet are synchronized according to the network planning.

Background Information

The calculation of PTP clock source is based on the clock subnet. Each clock subnet calculates its own current clock source separately. For an NE, only a time domain is supported at a time. According to the actual networking situation, the network planning personnel need to divide the entire network into different clock subnets in planning the clock network. Within each subnet, time synchronization can be implemented for all clocks, to meet the requirement of customers. Each BC or OC equipment can only be configured with a clock subnet. The clock source should be selected in the same clock subnet. The packets sent from different clock subnets are discarded by the NE.

Navigation Path

In the NE Explorer, select an NE and then choose Configuration > Clock > PTP Clock > PTP Clock Subnet Configuration from the Function Tree. Click the PTP Clock Subnet tab.

Parameters

Parameter

Value

Description

NE Name

For example: NE7183

Indicates the NE name.

PTP Clock Subnet No.

0 to 255

Default: 0

Specifies the clock subnet number to which the NE belongs.

NOTE:
  • The NEs that have the same subnet number belong to the same clock subnet.
  • For the equipment that is in the BC or OC work mode, it can belong to only one clock subnet, and its clock source can be selected only in the same clock subnet.
