Configuring the G.8275.1 Synchronization Function on the router Where an Atom GPS Module Houses

You need to enable G.8275.1 in the system view of a device, configure the device as a T-BC, specify the domain to which the device belongs to, and enable the static configuration of the status of the T-BC interface. After enabling G.8275.1 in the system view, you need to enable G.8275.1 in the interface view.

Context

Perform the following operations on the T-BC:

Procedure

Run system-view
The system view is displayed.
Run ptp enable
PTP is enabled.
Run ptp profile g-8275-1 enable
G.8275.1 is enabled.
Run ptp device-type t-bc
The device type is set to T-BC.
(Optional) Run ptp domain domain-value
The domain where the device resides is configured.

Devices in the same clock domain can exchange G.8275.1 packets to synchronize time signals.
(Optional) Configure automatic asymmetry measurement for fibers.
1. Run ptp asymmetry-measure enable
  Automatic asymmetry measurement is enabled on the device.
2. Run ptp passive-measure enable
  The performance monitoring function is enabled on the passive interface of a G.8275.1 device.
3. Run ptp passive-measure alarm-threshold alarm-threshold-value
  An alarm threshold is configured for the time offset (time difference between the master and slave clocks) on the passive interface of a G.8275.1 device.
(Optional) Configure the clock source access control function.
1. Run ptp acl enable
  The clock source access control function is enabled.
2. Run ptp acl-permit-clockid clockid-value
  A clock ID is configured for a T-BC to allow for local BMC algorithm.
(Optional) Run ptp max-steps-removed max-steps-removed-value
The maximum number of hops for time synchronization is configured.

A clock source is considered unavailable if stepsRemoved in the Announce packets received by the clock source is greater than or equal to max-steps-removed-value.
Run commit
The configuration is committed.
Run interface interface-type interface-number
The interface view is displayed.
Run ptp enable
PTP is enabled on the interface.
(Optional) Run ptp notslave disable.
The notslave attribute of the interface is set to FALSE.
(Optional) Run ptp local-priority local-priority-value.
The local priority of a PTP interface is set.
(Optional) Run ptp asymmetry-correction { positive | negative } correction-value
The asymmetric correction time for sending G.8275.1 packets on the interface is set.
(Optional) Run ptp clock-step { one-step | two-step }
The timestamping mode of the synchronization packets sending by the G.8275.1 port is set.
Run commit
The configuration is committed.
