•
Units.
Time unit for the period of generation of synchronization messages. It can

This sets whether messages should be sent with
authentication information.
•
Authentication Key.
If the previous option is enabled it determines which of the
authentication keys defined in the previous block is used to authenticate the

PTP CONFIGURATION
The
PTP
menu is only useful when the SWT-L3 is equipped with PTP ports
.
The equipment supports the IEEE 1588v2 (PTP) protocol according to Power Profile in
2-step mode, although it accepts 1-step and converts automatically to 2-step.
When the PTP protocol is in execution, the user can individually configure the execution of
the protocol in each of the ports.
The equipment supports tuning, although it only does it with the PTP messages of a
specific PTP domain and a specific VID, of the many that it can send; both the PTP domain
and the VID are configurable parameters. The calculated tuning will be used to adjust all
the corrections calculated by the equipment, regardless of the PTP domain and/or the
VLAN to which they belong.
In the PTP messages, typical of the Peer-to-Peer mode, for the calculation of the line delay,
the same PTP and VID domain will always be used as the one configured for tuning, as
well as the established 802.1p priority.
As optional feature, the equipment can be synchronized at hour level from the PTP
messages with which the tuning is performed, although the equipment never behaves as a
PTP client.
