Configuring the XIP 3901 - JPEG - XS v1.0 Application with its Web Interface
PTP Panel
Property Description
Domain
Number
Specify the PTP Domain Number the card is to use to synchronize its clock. A domain is
an interacting set of clocks that synchronize to one another using PTP. Clocks are
assigned to a domain by virtue of the contents of the Subdomain name or the domain
Number (IEEE 1588-2008) fields in PTP messages they receive or generate.
The range is 0 to 127. The default value is 127.
Announce
Interval
Specify the Announce message interval used by the parent clock (Boundary clock).
Announce Interval range is: 0.125, 0.250, 0.500, 1, 2, 4, 8, 16 seconds. The default value is
0.125 second.
Announce
Receipt Timeout
Count
Specify the Announce Receipt Timeout used by the parent Boundary clock. The
Announce Receipt Timeout range is 2 to 10 seconds. The default value is 3 seconds.
DSCP Sets the quality of service priority for outgoing PTP packets. The range is 0 to 63. The
default value is 46.
PTP Status
ETH1 & ETH2 Shows the status of the ETH interfaces. The possible values are:
Faulty: The protocol’s fault state.
Listening: The port is waiting for the announceReceiptTimeout to expire or to receive an
Announce message from a master.
Uncalibrated: One or more master ports have been detected in the domain.
Slave:
The port is synchronized to the selected master port.
PTP Locked Shows the card’s current overall PTP lock status to the network’s Grandmaster clock.
Green: The card has successfully locked to the network’s PTP Grandmaster clock.
Red: The card is not locked to the network’s PTP Grandmaster clock.
Interface In Use Shows the interface that is currently receiving PTP (ETH1, ETH2).
Grand Master
Clock ID
Shows the Grand Master’s clock ID (for example, Tektronix).
Parent Master
Clock ID
Shows the Boundary clock’s ID (Switch ID).
UTC Offset (sec) Shows the current time offset between UTC and PTP. This value can change.
The possible range is -32768 to 32767.
Time Source Shows the source of time used by the grandmaster clock.
The possible values are Atomic Clock, GPS, Terrestrial Radio, PTP, NTP, Hand Set, Other,
Internal Oscillator.
Sync mode Shows the Sync Mode from the Grand Master. A boundary clock cannot have a different
setting.
The possible values are One Step, Two Step.
Steps removed Shows how many hops the card is from the Grandmaster. This is used by the Best Master
Clock Algorithm (BCMA).
The possible values are 0 to 65535.
Priority 1 Shows the first priority. This is used in the execution of the Best Master Clock Algorithm
(BCMA). The Priority (1 or 2) with the lowest value will be used as the clock reference.
The possible values are 0 to 255.
