option available.
Port List
Shows the ports configured for that Clock Instance.
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
The options for Transport protocol used by the PTP protocol engine are:
•
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 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 (PCP) values used for PTP frames. The default value is 1. Other
values available are from 0 to 7.
