Two Gigabit Ports
The PTP daemon status and configuration is supported from two PTP companion utilities
ptpstatx
and
ptpconfigx
, where x is network port 0 (
eth0)
or 1 (
eth1)
. The following table shows the
Sonoma utilities that pertain to PTP:
Daemon Status Configuration
PTP
ptpd0
ptpd1 ptpstat0
ptpstat1 ptpconfig0
ptpconfig1
PTP can be enabled on one or both network ports (
eth0
and
eth1
). If PTP is enabled on only one
port, then
eth0
is the network port identifier and you would use
ptpstat0
and
ptpconfig0
for
PTP status and configuration. If PTP is enabled on both ports, then both
eth0
and
eth1
will be used.
PTP Configuration
and Status
The default PTP configuration settings in the Sonoma are shown below. If you need to modify these
settings then you will need to reconfigure the PTP Subsystem. You may perform the configuration
from either a
telnet
or
ssh
session, or the local RS-232 console. Default PTP settings are:
Port 0 (eth0) Port 1 (eth1)
Sync Interval 1 second 1 second
Announce Inverval 2 seconds 2 seconds
Priority 1 128 128
Priority 2 128 128
Delay Mechanism E2E E2E

PTP Time Mode PTP PTP
PTP TTL 1 1
PTP Configuration Using the Network or Serial Port
The
ptpconfig0
or
ptpconfig1
command starts an interactive shell script that will allow you to
configure the PTP Subsystem of the Sonoma. You will be prompted to set PTP parameters as fol-
lows:
ETH Port: 0 or 1
Sync Interval (Per Second): 1, 2, 4, 8, 16, 32, 64, 128
