After setting this parameters, click at the Save button. An instance based on the
previous configurations will be created.
At the instance created, select at the checkboxes which ports will be members of the
instance. In the example given, ports that must be in the same parameters instance
are:
o
Port where PTP Grandmaster Clock is connected;
o
Port where there are switch-to-switch connections;
o
Port where PTP slave clocks are connected. In this example, port
where Merging Unit is connected.
Repeat these steps on all switches that are being used to forward PTP messages. In
the example given, all switches should be configured with the parameter shown
above, and ports connecting switch-to-switch and PTP clocks should be members of
the instance.
PTP usage without VLANs
Consider the assumptions below:
1.
PTP information given by PTP Grandmaster Clock as:
o
Domain 0;
o
Transmitted over Ethernet without VLAN information and PCP is 0
o
Operation mode is two-step;
o
Delay mechanism is peer-to-peer.
2.
There is no VLAN being used by switches, that is, GOOSE, Sampled Values,
PTP and other messages at the LAN belong to the same LAN;
In addition, switches should be transparent clocks to the slaves.
With information given above, it is possible to go to the Settings PTP menu to start
configuration process. The configuration of the PTP should be as follows:
By default, no PTP clock instances are available. Thus, it is necessary to create an
instance to be used as P2P transparent clock. Click at the Add New PTP Clock button
to create a new instance.
After instance is displayed, configuration of the parameters should be as follows:
