9.5.7.2.2 End to End Default Profile Server Only Mode
This section describes how to provision a PTP End to End Default Profile Server Only Mode Clock.
1.
Select Server Only for PTP Clock Mode
Select 'Server Only' from the 'PTP CLOCK MODE' dropdown.
2.
Select Network Protocol
Select the network protocol PTP will operate on using the 'NETWORK PROTOCOL' dropdown.
The Network protocol should be consistent across the network subnet. The supported options are IPv4 (layer
4) and PTP over Ethernet (layer 2). By default the network protocol is set to IPv4 (UDP).
Note:
IPv4 is the most common PTP Network Protocol.
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 1 and Priority 2 Fields
Modify the 'PRIORITY #1' and 'PRORITY #2' fields if required, otherwise it is recommended that these are left
as their default values.
These parameters modify the automatic selection of server clocks in PTP networks. Lower values mean that
the unit will be preferred against other server capable clocks during the selection process. The priority 1
value is used to manually select which server capable clock will become the grandmaster and will be used
in preference over other selection criteria including clock accuracy , so should be modified very carefully.
The priority 2 value is treated as the least important criteria, providing greater selection control between
otherwise-equal clocks
