Configuring Unicast Negotiation on a 1588 ATR Server

An router that functions as a 1588 ATR server needs to be enabled with unicast negotiation so that it can use Layer 3 unicast packets to establish clock links with a 1588 ATR client and use PTP packets to implement time synchronization over a third-party network.

Context

If the router only functions as a client in 1588 ATR client hop-by-hop mode, configuration on the server side is not involved.

Procedure

Run system-view
The system view is displayed.
Run ptp-adaptive enable
1588 ATR is enabled on the router.
Run ptp-adaptive device-type server
The router is configured to function as a 1588 ATR server.
Run ptp-adaptive time profile
The device is configured to support ITU-T G.8275.2.

After the ptp-adaptive time profile command is run, the default value of the clock domain changes to 44, and the value range changes to 44 to 63.
(Optional) Run ptp-adaptive domain domain-value
A 1588 ATR domain is configured for the router.

The 1588 ATR client and server must be in the same clock domain.
Run ptp-adaptive local-ip ip-address
The local IP address used for implementing Layer 3 unicast negotiation is configured.

During Layer 3 unicast negotiation, a 1588 ATR client initiates a connection request to a 1588 ATR server. The local IP address and server IP address uniquely identify a 1588 ATR Layer 3 unicast negotiation connection. Specifying a local loopback interface IP address as the local IP address is recommended to allow all the packets to be transmitted from the server to the client.
Run ptp-adaptive atr unicast-negotiate enable
1588 ATR unicast negotiation is enabled on the router.
Enable 1588 ATR on the outbound interface used to transmit 1588 ATR packets.
1. Run interface interface-type interface-number
  
  The interface view is displayed.
2. Run ptp-adaptive atr enable
  
  1588 ATR is enabled on the interface.
3. Run commit
  
  The configuration is committed.
4. Run quit
  
  The system view is displayed.
Run commit
The configuration is committed.
