PTP Clock Configuration
Delete
Check this box and click on 'Save' to delete the clock instance.
Clock Instance
Indicates the Instance of a particular Clock Instance [
0
..
3
]. Click on the linked Clock Instance
number to edit the Clock details for the selected instance.
Device Type
Indicates 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.
BC-frontend
- clock's Device Type is Boundary Clock frontend.
Port List
Set a check mark for each port configured for this Clock Instance.
2 Step Flag
Static member: defined by system, true if two-step Sync events and Pdelay_Resp events used.
Clock Identity
Shows the 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 the ‘Device
Type’ parameter.
In a unicast Slave only clock you must also 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 Port VLAN mode == None, and the
port is member of the VLAN.
VID
VLAN Identifier used for tagging the PTP frames.
