CHAPTER 4
WEB OPERATION & 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.
VID:
VLAN Identifier used for tagging the PTP frames.
PCP:
Priority Code Point value used for PTP frames.
Click on the Clock Instance number to edit the Clock details.
