system_identity Structure

This structure defines settings for system_identity for gPTP

C/C++ Declare

typedef struct __declspec (align(1))
{
   uint8_t priority_1;
   clock_quality clock_quality;
   uint8_t priority_2;
   uint64_t clock_identity;
}system_identity; 

Visual Basic .NET Declare

<StructLayout(LayoutKind.Sequential, Pack:=1)> Public Structure system_identity
   Dim priority_1 As Byte
   Dim clock_quality As clock_quality
   Dim priority_2 As Byte
   Dim clock_identity As UInt64
End Structure 

C# .NET Declare

[StructLayout(LayoutKind.Sequential,Pack=1)]
public struct system_identity
{
   public byte priority_1;
   public clock_quality clock_quality;
   public byte priority_2;
   public UInt64 clock_identity;
}

Remarks

Item	Description
priority_1	Priority1 sets the ordering priority. Lower values set a better ClockMaster. See gPTP spec, 8021AS for more details and restrictions.
clock_quality	See clock_quality structure
priority_2	priority2 uses a similar scheme as priority1. See gPTP spec, 8021AS for more details.
clock_identity	clockIdentity attribute is defined in 7.5.2.2 of IEEE Std 1588-2019
