    Table 1: show ptp global-information Output Fields

    Field Name

    Field Description

    PTP Global Configuration

    Configured PTP, master, and slave parameters.

    Profile Type

    Profile Type

    Domain Number

    PTP domain with values from 0 through 127. The default value is 0. Only one PTP domain is supported at any given point in time.

    Transport Encapsulation

    Name of the encapsulation type: Ipv4.

    Clock mode

    Clock mode is either boundary or ordinary.

    Priority Level1

    Priority value of the clock: 0 through 255. The default is 128. The lower value takes precedence.

    Priority Level2

    Priority value of the clock: 0 through 255. The default is 128. This value is used to differentiate and prioritize the master clocks when the priority1-value is the same for different master clocks in a network. The lower value takes precedence.

    Unicast Negotiation

    Method by which the announce, synchronization, and delay-response packet rates are negotiated between the master and the slave or client before a PTP session is established. Unicast negotiation is enabled or disabled.

    ESMC QL From Clock Class

    Denotes whether the conversion from clock class to QL is enabled or disabled.

    Clock Class/ESMC QLl

    Denotes the user defined clock class to QL conversion.

    SNMP Trap Status

    Denotes the SNMP trap generation status (Enabled or Disabled).

    Slave Parameters

    Parameters configured on the slave clock:

    • Sync Interval—Log mean interval between synchronization messages requested during unicast negotiation.
    • Delay Request Interval—Log mean interval between delay-response messages requested during unicast negotiation.
    • Announce Interval—Log mean interval between announce messages requested during unicast negotiation.
    • Announce Timeout—Number of announce messages missed and detected by the slave, resulting in the slave identifying the master as unreachable.
    • Grant Duration—Length of time a unicast grant is assigned for unicast negotiation.

    Master Parameters

    Parameters configured on the master clock:

    • Sync Interval—Log mean interval between synchronization messages sent to a configured manual slave.
    • Announce Interval—Log mean interval between announce messages sent to a configured manual slave.
    • The minimum and maximum parameters below are the minimum and maximum values accepted during unicast negotiation from remote clients:

      • Min Announce Interval—Log2 value, which means that announce messages are sent once every eight seconds. The value should be in the range 0 to 3.
      • Max Announce Interval—Maximum acceptable interval between announce messages. The value should be in the range 0 to 3.
      • Min Sync Interval—Minimum acceptable interval between synchronization messages.
      • Max Sync Interval—Log2 value, which means that the maximum synchronization rate is 128 messages per second.
      • Min Delay Response Interval—Minimum acceptable interval between delay-response messages.
      • Max Delay Response Interval—Maximum acceptable interval between delay-response messages.
    • Clock Step—Synchronous timing message: one-step or two-step. With two-step, a subsequent follow-up message is received after the first synchronous message.
    • Holdover In Specification Time—Display the status of holdover-in-specification time. The default time for holdover-in-specification state is 86400 seconds (24 hours).

    Number of Slaves

    Number of slaves configured on the router.

    Number of Masters

    Number of masters configured on the router.

    Stateful Ports

    Total number of interfaces that are configured to be stateful or dynamic. A stateful port functions as both a master port and a slave port.

    Transparent-clock-config

    Display whether transparent clock is configured.

    Transparent-clock-status

    Display the status of the transparent clock operation. The following status would be displayed:

    • N/A—Transparent clock is not configured.
    • Active—Transparent clock is configured and working properly.
    • sync-in-progress—This is a temporary state. During startup, all the PHYs are synchronized with each other. This status can also occur when a new MIC is plugged in to the router (for example, ACX4000) and all the PHYs go through the synchronization cycle again.

      Note: Transparent clock operation is disabled during the synchronization of PHYs.

    • Inactive—Transparent clock is configured but not working properly. This would indicate a hardware error in PHY timestamping logic.
