(Optional) Adjusting Parameters for Establishing a Unicast Negotiation Connection

Adjustable parameters include the maximum number of consecutive Announce packets that the client fails to receive (If the number of unreceived Announce packets exceeds the threshold, the client determines that the connection to the server fails), duration of the Sync, Delay_Resp, and Announce packets (After the duration of a Sync packet, a Delay_Resp packet, or an Announce packet expires, the client re-establishes the connection with the server), DSCP value (the DSCP value ensures that 1588v2 packets reach the destination even if a congestion occurs on the network), and the interval at which the server sends Sync, Delay_Resp, and Announce packets.

Context

Adjustable parameters on a client are as follows:

  • Maximum number of consecutive Delay_Resp packets that the client fails to receive
  • Duration field values in Sync, Delay_Resp and Announce packets
  • DSCP value for 1588 ACR packets
  • Interval at which Sync, Delay_Resp and Announce packets are sent

Adjustable parameters on a clock server are as follows:

  • DSCP value for 1588 ACR packets

Procedure

  1. Run ptp-adaptive dscp dscp-value

    The DSCP value in 1588 ACR packets is set.

    Setting a large DSCP value to ensure that 1588v2 packets reach the destination even if a congestion occurs on a network. This value is adjustable on both the client and clock server.

  2. Run ptp-adaptive { announce-duration | sync-duration | delay-resp-duration } duration-value

    The duration field value is set for each type of 1588 ACR packet.

  3. Run ptp-adaptive request sync-interval interval-value

    The interval at which an ACR clock server sends Sync packets is set.

  4. Run ptp-adaptive request announce-interval announce-interval-value

    The interval at which an ACR clock server sends Announce packets is set.

  5. Run ptp-adaptive request delay-resp-interval interval-value

    The interval at which the 1588 ACR-enabled server sends Delay_Resp packets is set.

  6. Run ptp-adaptive announce receipt-timeout timeout-time

    The allowable maximum number of consecutive Announce packets that the client fails to receive is set.

  7. Run commit

    The configuration is committed.
