The slave clock interface responds to the upstream PTP master clock.
To configure the PTP slave clock interface:
Configure the interface for the slave clock.
1.
[edit protocols ptp slave]
user@host# edit interface interface-name
Configure the upstream multicast PTP master clock source parameters.
2.
[edit protocols ptp slave interface interface-name]
user@host# edit multicast-mode
Specify the encapsulation type for PTP packet transport as Ethernet or IEEE 802.3.
3.
This statement is mandatory.
[edit protocols ptp slave interface interface-name multicast-mode]
user@host# set transport ieee-802.3
Alternatively, specify the encapsulation type as Ethernet with the link-local multicast
address to be used in the sending of PTP messages. If you specify the
attribute, the master clock chooses either of the two MAC addresses defined in the
IEEE 1588-2008 standard. When you configure this option, the system attempts to
use the 01 -80-C2-00-00-0E MAC address (link-local multicast MAC address) for
multicast transmission. If this MAC address is not available, the 01-1B-19-00-00-00
address (standard Ethernet multicast address) is used as the second priority. The
standard Ethernet multicast address is used by default. You need to explicitly configure
the link-local multicast address.
[edit protocols ptp slave interface interface-name multicast-mode]
user@host# set transport ieee-802.3 link-local
After you have configured the PTP over Ethernet slave clock interface, enter the
command in configuration mode.
