Configuring the PTP over Ethernet Master Boundary Clock Interface

Configuring the PTP over Ethernet Slave Clock Parameters

After you configured the master boundary clock parameters for PTP over Ethernet with
multicast transmission of PTP traffic, complete the configuration of the master boundary
clock by configuring an interface to act in the role of the master clock.
To configure a PTP over Ethernet master boundary clock interface:
Configure the interface on which to respond to downstream PTP slave ports or clients.
1.
[edit protocols ptp master]
user@host# edit interface interface-name

clients.
[edit protocols ptp master 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 master 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.

user@host# set transport ieee-802.3 link-local
After you have configured the PTP over Ethernet master clock interface, enter the
command from configuration mode.
An interface on which the master clock is configured is called a master interface and an
interface on which the slave clock is configured is called a slave interface. A master
interface functions as the master port and a slave interface functions as the slave port.
Because PTP over Ethernet uses multicast addresses, a slave port can automatically
