Wr Slave @ Wr0>Wr1 / Ptp Fan-Out; Manual Free-Running; Custom - Safran WR-ZEN Series User Manual

5.2 General Timing Management
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 con-
figured as IEEE 1588- 2008 (PTPv2) masters to distribute timing to 3rd party
devices.
5.2.1.9 WR Slave @ wr0>wr1 / PTP Fan-Out
Web GUI selection: BC: wr0->wr1|PTP
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.
5.2.1.10

Manual Free-Running

Web GUI selection: FR: Manual
This preset is useful for laboratory and test networks where each node is dis-
ciplined 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.
5.2.1.11

Custom

The Custom Preset has been designed to allow unique selections for timing
source and fanout settings in order to meet any kind of user needs. If the user

The primary timing source is provided using WR through interface wr0. It
can failover to a secondary timing source provided using WR through inter-
face wr1.
All ports except wr0 and wr1 are configured as PTP slaves.
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).
Caution: It is highly recommended to avoid integrating a Manual
Free-Running device to a timing network in production as in some
corner cases the BMCA/FOCA algorithms might select this timing
source when it is not the expected choice.
