receive the multicast messages from the master clock, and can begin sending messages
to the master clock without any pre-provisioning. The master boundary clock synchronizes
time through a slave boundary port.
To configure PTP over Ethernet with multicast master and slave ports, you must include
the multicast-mode transport ieee-802.3
and
interface interface-name]
levels, respectively.
To configure a PTP over Ethernet master boundary clock and slave boundary clock for
multicast transmission, complete the following tasks:
Configuring the PTP over Ethernet Master Boundary Clock Parameters on page 275
Configuring the PTP over Ethernet Master Boundary Clock Interface on page 277
Configuring the PTP over Ethernet Slave Clock Parameters on page 277
Configuring the PTP over Ethernet Slave Clock Interface on page 279
To configure the parameters of a PTP over Ethernet master boundary clock:
Configure the clock mode.
1.
[edit protocols ptp]
user@host# set clock-mode boundary
Configure the master clock.
2.
[edit protocols ptp]
user@host# edit master
(Optional) Specify the log mean interval between announce messages—from 0
3.
through 4. By default, one announce message is sent every two seconds. This
configuration is used for manual clock clients. The master boundary clock sends
announce messages to manual clock clients as specified in the announce-interval
value.
[edit protocols ptp master]
user@host# set announce-interval announce-interval-value
Configure the interface on which to respond to downstream PTP clients or slave ports.
4.
[edit protocols ptp master]
user@host# edit interface interface-name

messages—from 0 through 4. The default value is 4.
