Delay mechanism Displays which PTP delay mechanism is currently used by OTMC 100 .
The value of this parameter may either be E2E (end-to-end) or P2P
(peer-to-peer). The PTP delay mechanism used depends on the PTP
profile selected in the
PTP configuration (see page 62 ).
Sync interval [s] Displays the mean synchronization interval for multicast messages
(interval between successive Sync messages).
This parameter is set in the PTP configuration (see page 62 ).
Sync Interval = 2 Log sync interval seconds, see IEEE 1588-2008, clause
8.2.5.4.3.
Announce interval [s] Displays the mean time interval between successive Announce
messages. See IEEE 1588-2008, clause 8.2.5.4.1.
This parameter is set in the PTP configuration (see page 62 ).
Announce interval = 2 Log announce interval seconds.
Announce receipt timeout Displays the number of "Announce Interval" intervals that have to pass
without the receipt of an Announce message before an
ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES event occurs. See
IEEE 1588-2008, clause 8.2.5.4.2.
This parameter is set in the PTP configuration (see page 62 ).
Minimum pdelay request
interval [s] Displays the minimum permitted mean time interval between successive
Pdelay_Req messages. See "logMinPdelayReqInterval" in
IEEE 1588-2008.
Only available for profiles Default P2P, Power
(C37.238-2011), Power (C37.238-2017), and Power utility
(61850-9-3:2016).
This parameter is set in the PTP configuration (see page 62 ).
Minimum pdelay request interval = 2
Log min pdelay request interval
seconds, see
IEEE 1588-2008, clause 8.2.5.4.5.
Minimum delay request
interval [s] Displays the minimum permitted mean time interval between successive
Delay_Req messages. This value is determined and advertised by a
master clock based on the ability of the master.
Only available for PTP
profile Default E2E.
This parameter is set in the PTP configuration (see page 62 ).
Minimum delay request interval = 2
Log min delay request interval
seconds, see
IEEE 1588-2008, clause 8.2.5.3.2.
Peer mean path delay [ns] Displays the estimate of the current one-way propagation delay on the
link computed using the peer delay mechanism. If the delay mechanism
is E2E, this value is zero. See IEEE 1588-2008, clause 8.2.5.3.3.
Delay asymmetry [ns] Displays the asymmetry delay. The asymmetry delay is defined to be
positive when the master-to-slave or responder-to-requestor propagation
time is longer than the slave-to-master or requestor-to-responder
propagation time. See IEEE 1588-2008, clause 7.4.2.
Time (master -> slave) = meanPat delayAsymmetry
Time (slave -> master) = meanPathDelay - delayAsymmetry
