Users Guide

For both L2 and L3 interfaces, the configured source IP address is used as the source IP address for unicast transport from
the master device to the slave device.
OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/1)# ip address 30.30.30.1/24
OS10(conf-if-eth1/1/2)# ptp transport ipv4 unicast master
OS10(conf-ethernet1/1/2-ptp-ipv4-master)# source 20.20.20.1
OS10(conf-ethernet1/1/2-ptp-ipv4-master)# slave 20.20.20.2
OS10(conf-ethernet1/1/2-ptp-ipv4-master)# exit
OS10(conf-if-eth1/1/2)# ptp enable
In this example, a source address different from the interface IP address is configured because the slave device is reachable
in a different subnet of the source IP address.
Interface 1 becomes the slave device and interface 2 becomes the master clock for the other devices.
Example: Configure end-to-end transparent clock
Ensure that you configure the following on the OS10 switch:
● Enable IP multicast routing.
● Configure the IP address on the PTP-enabled interfaces.
● Enable PIM sparse mode on the PTP-enabled interfaces.
● Configure a rendezvous point (RP) or a bootstrap router (BSR).
● The OS10 switch sends all PTP packets to the multicast group address, 224.0.1.129. Ensure that the PTP-enabled interfaces
are part of this multicast group. Use IGMP and PIM for multicast routing.
You can enable the end-to-end transparent clock globally on the OS10 switch. The system applies this configuration on all the
PTP-enabled interfaces. In the following example, port 1 is connected to the grandmaster clock and port 2 is connected to a
slave device. Ports 1 and 2 are members of the multicast group, 224.0.1.129.
NOTE: OS10 does not support PTP multicast IPv6 negotiation in transparent clock mode.
To configure an end-to-end transparent clock, use the following command:
OS10(config)# ptp clock end-to-end-transparent
The system updates the residence time in the correction field of the message and forwards the PTP messages.
