Purpose
The range for the number is from 0 to 128.
(Optional)
Configures the priority1 value to use when advertising this
clock. This value overrides the default criteria (clock
quality, clock class, and etc.) for best master clock selection.
Lower values take precedence.
The range for the value is from 0 to 255.
(Optional)
Configures the priority2 value to use when advertising this
clock. This value is used to decide between two devices
that are otherwise equally matched in the default criteria.
For example, you can use the priority2 value to give a
specific switch priority over other identical switches.
The range for the value is from 0 to 255.
(Optional)
Configures the encapsulation that is to be used for PTP. In
Layer 3 encapsulation, PTP packets are encapsulated with
IP + UDP frame. In Layer 2 encapsulation, PTP packets
are encapsulated within the Ethernet frame. The default
PTP encapsulation is Layer-3; PTP mode is Boundary.
Layer 2 encapsulation is supported only with AVB.
(Optional)
Configures the PTP device mode. The default mode is
boundary-clock. The generalized-PTP mode is used for
AVB. The transparent-clock peer-to-peer mode is added
for experimental purpose, not supported officially.
(Optional)
Configures the maximum estimate switch latency value in
nano-secs (ns). This value is used in AVB. The range is 0
- 2147483647. The default value is 5000.
(Optional)
Displays information about foreign masters.
(Optional) Displays link delay and residency delay
information for all interfaces. It is used in AVB.
(Optional) Displays parent clock information.
(Optional) Displays local clock time property information.
