nature of UDP, it is recommended to set to the shorter duration since the shorter the duration, the fresher is UPnP

4.21 PTP (IEEE1588)
4.21.1 Configuration
Click on “Add New PTP Clock” button to create a new entry.
Clock Instance:
Indicate the Instance of a particular Clock Instance. The valid instance number is from 0 to 3.
Device Type:
Indicate the Type of the Clock Instance. There are five Device Types.
Ord-Bound:
Clock's Device Type is Ordinary-Boundary Clock.
P2p Transp:
Clock's Device Type is Peer to Peer Transparent Clock.
E2e Transp:
Clock's Device Type is End to End Transparent Clock.
Master Only:
Clock's Device Type is Master Only.
Slave Only:
Clock's Device Type is Slave Only.
2 Step Flag:
True if two-step Sync events and Pdelay_Resp events are used
Clock Identity:
This shows unique clock identifier.
One Way:
If true, one-way measurements are used. This parameter applies only to a slave. In one-way mode no delay
measurements are performed, i.e. this is applicable only if frequency synchronization is needed. The master always
responds to delay requests.
Protocol:
Select transport protocol used by the PTP protocol engine.
Ethernet:
PTP over Ethernet multicast.
ip4multi:
PTP over IPv4 multicast.
ip4uni:
PTP over IPv4 unicast.
Note: IPv4 unicast protocol only works in Master only and Slave only clocks. In a unicast Slave only clock you also need
to configure which master clocks to request Announce and Sync messages from.
VLAN Tag Enable:
Enables the VLAN tagging for the PTP frames.
Note: Packets are only tagged if the port is configured for vlan tagging. i.e: Port Type != Unaware and PortVLAN mode
== None, and the port is member of the VLAN.
