The clock offset distribution section displays information about the received PTP clock.
R/W Allows specifying if the PTP clock is unicast or multicast.
R/W PTP clock domain number (from 0 to 128)
R/W Syntonized: means that IQOYA's clock is the same as the Grandmaster PTP, but they are not
synchronous (delay between the two clocks).
Synchronous clock is obtained thanks to E2E or P2P modes, which serve to compensate the delay
between Grandmaster PTP clock and IQOYA.
E2E is a more universal setting (it consists of requests and answers between the node (IQOYA) and the
Grandmaster PTP clock unit).
P2P provides higher clock sync precision but requires full PTP support from all participating switches
(between IQOYA and related clock master.)
In case the PTP clock is generated by an IQOYA, the PTP mechanism must be the same as in the
IQOYA master: syntonized.
R/W Select the network interface that receives the PTP
R/W Off: X/LINK subscribes to the multicast PTP clock which can be generated by any source IP address.
Include: X/LINK subscribes to the multicast PTP clock which is generated only by the listed source IP
addresses.
Exclude: X/LINK subscribes to the multicast PTP clock which is generated by any source IP address,
with exception of the listed IP addresses..
R/W
Allows declaring the source IP addresses to be included or excluded. Click on
the list.
¨R/W QoS assigned to the PTP frames. Select the value from the drop down list. For optimal QoS on PTP,
"Expedited forwarding (EF)" value is recommended.
R/W This parameter defines the condition for being synchronized to the PTP clock. The lower the value, the
better the phase with the PTP clock. Lower values require a deterministic network. For networks that
introduce an erratic jitter to the PTP frames, the value must be increased.
Default value is 0.5 sample. It can be increased up to 64 samples.
R/W It defines the sensibility of the slave clock to the PTP packet jitter. Enter a value between 500 (for a high
sensitivity) and 100 (for a low sensitivity). Default value is 500
