2.
Network Protocol
By default, the 'NETWORK PROTOCOL' is set to Layer 2 (Ethernet), which will send packets via the Ethernet
data layer
3.
Select Operating Mode
Select the operating mode for the PTP network from the 'OPERATING MODE' dropdown.
Operating mode is a network wide parameter. The configurable options are 'One Step' or 'Two Step'.
Note:
Select Two Step operation if the Operating Mode is unknown.
4.
Delay Mechanism
By default the 'DELAY MECHANISM' will be set to E2E which will set the delay mechanism to end to end as
defined in IEEE 1588v2-2008.
5.
Configure Priority Fields
The 'PORT LOCAL PRIORITY' setting doesn't have a significant behavioural impact in client only mode and
the clock local priority setting has no impact. The port local priority only affects the BMCA comparison of
different servers it can see, as it can't consider itself as a server candidate.
Clock Local Priority
The 'CLOCK LOCAL PRIORITY' doesn't affect the execution of the BMCA in client only mode, as the port
cannot consider itself as a potential server in the BMCA process. Therefore, it can be left unchanged.
Modify these fields to achieve your desired BMCA outcome.
Port Local Priority
The 'PORT LOCAL PRIORITY' is applied to the announce messages received on the port from a potential
server when comparing that potential server to the local clock or other potential server. Setting this to a lower
value will give preference to foreign servers connected to this port, against servers connected to a different
port. The input range is 1 to 255, where 1 is the highest priority. The default setting is 128. This attribute is not
used when operating as a grandmaster.
