1.4 PTP parameters and data sets
The PTP protocol defines several parameters and data sets that the user can read and/set.
The parameters and data sets are described in chapter 15 of the IEEE1588 Std 2008.
The OnTime PTP protocol stack support both PTP version 1 (IEEE1588 Std 2002) and
version 2 (IEEE1588 Std 2008). A subset of the version 2 parameters and data sets below
will be available in case version 1 is used.
1.4.1 ClockDesc data set
Parameter
Type Read/Write Description
clockType Text Read-only The value clockType shall indicate
the type of PTP node (OC = 0x01,
BC = 0x02, P2P TC = 0x04, E2E

0x10, Private use: 0xFF - 0x20) as
defined in Table 42 of IEEE 1588
Std 2008.
Example:
