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 Meridian II. You will be prompted to set PTP parameters as follows:
ETH Port:
0 or 1
Sync Interval (Per Second):
1, 2, 4, 8, 16, 32, 64, 128
Announce Interval (Seconds):
1, 2, 4, 8, or 16
Priority1:
0-255
Priority2:
0-255
Delay Mechanism:
E2E or P2P
Domain:
0-255
PTP Time Mode:
UTC or PTP
PTP TTL:
1-255
Transmission Mode
Multicast or Hybrid
One file is modified for each port. Either
/etc/ptp0.conf
for
eth0
or
/etc/ptp1.conf
for
eth1
. These
are non-volatile files stored in the FLASH disk
/boot/etc
directory. You must reboot Meridian II after
running this script for the changes to take effect.
The following is a transcript of the question and answer configuration utility provided by
ptpcon-
fig0 or ptpconfig1
. The user-entered parameters are underlined:
Meridian II(root@host~)-> ptpconfig0
