2.8.10 Configuring PTP
Precision Time Protocol (PTP) is a time protocol that can be used to synchronize com-
puters on an Ethernet network. VersaSync supports PTP Version1 and2, as specified in
the IEEE 1588-2002 and IEEE 1588-2008 standard, via one (1) Ethernet port. PTP is cur-
rently only available on eth1 in order to take advantage of the Spectracom
Timestamper.
VersaSync currently can be configured as a PTP Master Clock only.
Next to PTP specifications, this topic describes the PTP menu items and settings, and out-
lines how to set up VersaSync as a PTP Master.
