5.2.1.5 WR Slave @ wr0 / PTP Fan-Out
The primary timing source is provided using WR protocol through interface wr0.
The wr1 is configured as WR master and the ethernet ports (i.e., eth0 & eth1) are
configured as PTP masters.
This preset targets devices used as last hop with PTP. The primary timing source is
provided using WR protocol through interface wr0. The other port is configured as IEEE
1588-2008 (PTPv2) masters to distribute timing to 3rd party devices.
Note: PTP Master configuration: This preset only configures the role and
protocol (PTP or WR) used for all network interfaces with some default
settings. A specific configuration of PTP (e.g., Profile, packet rates, etc.) can
then be performed under the PTPv2 configuration tab if a valid license has
been detected.
5.2.1.6 WR Slave @ wr0>wr1 / PTP Fan-Out
The primary timing source is provided using WR through interface wr0. It can fail-
over to a secondary timing source provided using WR through interface wr1.
The ethernet ports (i.e., eth0 & eth1) are configured as PTP masters.
This preset targets critical devices used as last hop with PTP. The primary timing source is
provided using WR through interface wr0. It can failover to a secondary timing source
provided using WR through interface wr1.
Note: PTP on copper ports (eth0 & eth1): In v3.x, PTP will be activated on
copper ports only while using "PTP Fanout" presets or by manually enabling
while forcing the "Custom" preset. In default mode it is disabled.
5.2.1.7 Manual Free-Running
The primary timing source is the free running internal oscillator in the device.
All SFP ports (i.e., wr0 & wr1) are configured as WR masters.
The device announces itself as a Free-running GM using arbitrary timescale (ARB).
This preset is useful for laboratory and test networks where each node is disciplined by the
same free-running oscillator. Selecting this preset will also silence the possible warnings in
devices of the down-layers and will preclude the use of the holdover as it cannot learn from
a free-running oscillator.
