Multiport PTP
When only one PTP option is enabled it will be configured for
eth0
PTP Domain 0. If a second PTP
option is enabled then it will be configured for
eth1
PTP Domain 1. This configuration will allow
PTP to run as master on both ports.
If the PTP Domain is configured as the same value for both ports (for example, PTP Domain 0 on
eth0
and PTP Domain 0 on
eth1
) then
eth0
Port State will be master and
eth1
Port State will be
listening.
Disable the
PTP Protocol
The instructions below assume that the PTP Option has been installed on Port 0 (
eth0
) of your Me-
ridian II. To check, see the section titled
Option
at the beginning of this chapter.
To disable the Precision Time Protocol on Port 0 issue the following command:
chmod -x /etc/rc.d/rc.ptpd0
Copy the
rc.ptpd0
file to the non-volatile FLASH area like this:
cp -p /etc/rc.d/rc.ptpd0 /boot/etc/rc.d
Then:
reboot
Once PTP has been disabled, the user interface will no longer show the existence of PTP.
Re-Enable PTP
To re-enable PTP on Port 0, remove the
rc.ptpd0
file from the
/etc/rc.d
directory as shown below:
rm /boot/etc/rc.d/rc.ptpd0
Then:
reboot
NOTE
If PTP is also installed on Port 1, then follow the instructions above using
rc.ptpd1
.
