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.
1. Ord-Bound – clock’s Device Type is Ordinary-Boundary Clock.
2. P2p Transp – clock’s Device Type is Peer to Peer Transparent Clock.
3. E2e Transp – clock’s Device Type is End to End Transparent Clock.
4. Master Only – clock’s Device Type is Master Only.
5. Slave Only – clock’s Device Type is 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
It 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
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
See parameter Device Type
In a unicast Slave only clock you also need configure which master clocks
to request Announce and Sync messages from. See: Unicast Slave Configuration
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.
VID
VLAN Identifier used for tagging the PTP frames.
PCP
Priority Code Point value used for PTP frames.
