Optional Precision Time Protocol (PTP/IEEE-1588)
This chapter contains the configuration and status information for the optional Precision Time Pro-
tocol. PTP version 2 is supported. The PTP protocol running on RTM3205 is a full Grandmaster
Clock (default profile) implementation of the IEEE-1588-2008 standard.
Software Option
The PTP/IEEE-1588 protocol is an optional feature in the RTM3205. Read
Appendix I - Software
Options
if you need information on how to install a software option. To see whether this option is
installed on your RTM3205, use the
installed_sw_opts
command:
Command:
installed_sw_opts
RTM3205 reply: <no reply>
In this case, there is no PTP option installed. Contact EndRun Technologies if you would like to
obtain PTP for one or both ports. In the case below, PTP is installed on both ports.
Command:
installed_sw_opts
RTM3205 reply:
The PTP0 Daemon Option is Installed.
The PTP1 Daemon Option is Installed.
About PTP
The PTP implementation in RTM3205 is based on the distribution at the PTPd website:
For more information about the
ptpd
daemon and to obtain PTP Slave software, refer to the PTPd
website. When downloading PTP Slave software from the PTPd website, be sure to obtain this ver-
sion:
ptpd-2.2.2.tar.gz
.
An excellent book which describes the PTP Master and Slave operation is:
