(Optional) Configuring Time Attributes for 1588v2 Messages

(Optional) Configuring Time Attributes for 1588v2 Messages

Context

1588v2 switches exchange Announce, Sync, and Delay or Pdelay messages to send time information and maintain 1588v2 connections. You can set the interval at which a 1588v2 interface sends Announce, Sync, and Delay or Pdelay messages and the maximum number of Announce message receiving timeouts. Using the default time attribute values is recommended.

If switches exchange 1588v2 messages frequently and consume a lot of bandwidth resources, increase the interval. If the time synchronization accuracy is low, reduce the interval. If required clock synchronization accuracy is guaranteed, set the interval to a larger value.

Perform the following steps on a 1588v2 device.

Procedure

  • Configure time attributes for Announce messages.
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run ptp announce-interval announce-interval

      The interval at which the interface sends Announce messages is set. The following formula applies:

      Interval = 2n x 1/1024s, where n equals to announce-interval

      By default, announce-interval is 7, indicating that an interface sends an Announce message at an interval of 128/1024s.

      Remote timeout period of receiving Announce messages = Number of remote Announce message receiving timeouts (receipt-timeout) x Local interval at which Announce messages are sent (announce-interval)

    4. Run ptp announce receipt-timeout receipt-timeout

      The maximum number of Announce message receiving timeouts is set.

      By default, the maximum number of Announce message receiving timeouts is 3.

      Local timeout period of receiving Announce messages = Number of local Announce message receiving timeouts (receipt-timeout) x Remote interval at which Announce messages are sent (announce-interval)

    5. Run commit

      The configuration is committed.

  • Configure time attributes for Sync messages.
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run ptp sync-interval sync-interval

      The interval at which the interface sends Sync messages is set. The following formula applies:

      Interval = 2n x 1/1024s, where n equals to sync-interval

      By default, sync-interval is 3, indicating that an interface sends a Sync messages at an interval of 8/1024s.

    4. Run commit

      The configuration is committed.

  • Configure time attributes for Delay or Pdelay messages.
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run ptp min-delayreq-interval min-delayreq-interval

      The interval at which the interface sends Delay_Req messages is set. The following formula applies:

      Interval = 2n x 1/1024s, where n equals to min-delayreq-interval

      By default, min-delayreq-interval is 7, indicating that an interface sends a Delay_Req message at an interval of 128/1024s.

    4. Run ptp min-pdelayreq-interval min-pdelayreq-interval

      The interval at which the interface sends Pdelay_Req messages is set. The following formula applies:

      Interval = 2n x 1/1024s, where n equals to min-pdelayreq-interval

      By default, min-pdelayreq-interval is 7, indicating that an interface sends a Pdelay_Req message at an interval of 128/1024s.

    5. Run commit

      The configuration is committed.
