Meaning
Boundary Clock function based on IEEE1588-2002
(PTPv1).
For the MS20, MS30 and PowerMICE devices with
realtime modules and for MACH 104 and MACH 1040,
see sections "Devices without PTP hardware support" on
page 81 and "Devices with PTP hardware support" on
page 82.
Support for PTPv1 without special hardware. The device
synchronizes itself with PTPv1 messages received. This
mode does not provide any other functions, such as PTP
management or runtime measuring.
Select this mode if the device only has ports absent a
timestamp unit.
(PTPv2).
The one-step mode determines the precise PTP time with
1 message.
For the MS20, MS30 and PowerMICE devices with MM23
or MM33 modules, see sections
hardware support" on page 81
hardware support" on page
(PTPv2).
The two-step mode determines the precise PTP time with
2 messages.
Transparent Clock function based on IEEE 1588-2008
(PTPv2).
Here, the MS20, MS30 and PowerMICE devices with
MM23 or MM33 modules use only the one-step mode.
Here, the MACH 104 and MACH 1040 devices use only
the two-step mode. They support a receive rate of
8 frames/s max.
Support for PTPv2 without special hardware. The device
synchronizes itself with PTPv2 messages received. This
mode does not provide any other functions, such as PTP
management or runtime measuring.
Select this mode if the device only has ports absent a
timestamp unit.
