Label Description
Delete Check this box and click Save to delete the clock instance.
Clock Instance Indicates the instance of a particular clock instance [0..3]
Click on the clock instance number to edit the clock details
Device Type Indicates the type of the clock instance. There are five device types.
Ord-Bound: ordinary/boundary clock
P2p Transp: peer-to-peer transparent clock
E2e Transp: end-to-end transparent clock
Master Only: master only
Slave Only: slave only
Port List Set check mark for each port configured for this Clock Instance.
2 Step Flag Static member defined by the system; true if two-step Sync events and Pdelay_Resp events are used.
Clock Identity Shows a 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 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
