ptp domain

Function

The ptp domain command specifies the domain in which a device resides.

The undo ptp domain command restores the default domain.

By default, a 1588v2 device resides in domain 0.

Format

ptp domain domain-value

undo ptp domain

Parameters

Parameter	Description	Value
domain-value	Specifies the clock domain value.	In 1588v2 mode, The value is an integer ranging from 0 to 255. The default value is 0. In G.8275.1 mode, the value ranges from 24 to 43, and the default value is 24. In CU-106 mode, the value ranges from 24 to 43, and the default value is 24. In SMPTE-2059-2 mode, the value ranges from 0 to 127, and the default value is 127.

Usage Guidelines

Usage Scenario

A PTP network is large scale and allows multiple carriers to lease the PTP network as a bearer network. To transparently transmit PTP packets for specific carriers, the PTP network can be logically divided into clock domains. Each clock domain has a single clock source, and all devices in the domain synchronize clock signals with the clock source.

Precautions

This command is supported only by the admin AS.

The method of configuring a domain varies according to the device mode.

On the OC, BC, TC, TCOC, and T-BC, a domain can be configured only in the system view, not in the interface view.
After a domain is configured in the system view on the TCandBC, the BC interface uses the domain configured in the system view, and the TC interface needs to be configured with a domain in the interface view.
The GPS 3.0 module does not support this command.

Example

# Specify domain 4.

<HUAWEI> system-view
[~HUAWEI] ptp domain 4

# Specify the domain for a TCandBC.

<HUAWEI> system-view
[~HUAWEI] ptp device-type tcandbc
[*HUAWEI] interface GigabitEthernet 0/1/0
[~HUAWEI-GigabitEthernet0/1/0] ptp port-type tc
[*HUAWEI-GigabitEthernet0/1/0] ptp domain 1
