, 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
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
For more information, please refer to
Device Type
.
In a unicast Slave Only clock, you also need to configure which
master clocks to request Announce and Sync messages from.
For more information, please refer to Unicast Slave Configuration
VLAN Tag Enable
Enables VLAN tagging for 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.
VID
VLAN identifiers used for tagging the PTP frames
PCP
Priority code point values used for PTP frames
