Network from
master/boundary clock
Compensates the OWD based on the network configuration from the PTP
master or boundary clock to the SNP. Options include:
•
100M->1G->100G
•
100M->100G
•
1G->100G
•
10G->100G
•
100G->100G (default)
Note that the control makes an assumption based on how the switch
normally behaves internally. Use the OWD Offset parameter (below)
to manually compensate.
OWD Offset (microseconds)
Enter a compensation value to adjust the OWD setting that comes from
the Network From Master/Boundary Clock parameter (above). The range
is from -1000 to 1000 microseconds, with a default of 0. See
Connecting to
a PTP Source
(on page 26) for more information.
Negotiated PTP Unicast
Interface
When configured for Negotiated Unicast, you must select the interface to
receive timing data. Options are the four primary and four secondary IP
WANs, with
IP WAN 1 Primary
as the default.
Negotiated PTP Unicast
Master IP
When configured for negotiated Unicast, you must enter the IP address of
the PTP master device.
PTP Unicast Mode
By default, SNP uses Mixed mode. To reduce network traffic, you can
configure it to instead use only Unicast mode. When Negotiated Unicast is
enabled, you must select a single source IP for the PTP data, and the
specific IP WAN to receive it. In Non-Negotiated Unicast, SNP will use the
first one it finds exclusively.
Options are:
•
Disabled (default)
•
Non-Negotiated Unicast
•
Negotiated Unicast
