Release Information Statement introduced in Junos OS Release 15.2 for MX Series routers.

Description Configure multicast transmission of Precision Time Protocol (PTP) packets between

the master node and the slave node. The multicast method of transport of PTP packets

is applicable in environments in which PTP uses IEEE 802.3 or Ethernet encapsulation

for the transmission of PTP packets. Because PTP over Ethernet uses multicast addresses,

a slave port can automatically start receiving the multicast announce messages

transmitted by the master ports on a network and can also start communicating with

the master port with minimal or no configuration. Unlike PTP over IPv4 where IP addresses

are used to identify the master and slave ports, with PTP over Ethernet, multicast MAC

addresses are used in forwarding of PTP traffic.

NOTE: You can configure only multicast mode or only unicast mode of

transmission of PTP traffic on an interface at a point in time.

The remaining statements are explained separately. See CLI Explorer.
