● 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.
Example: Configure boundary clock with IPv4 unicast transport
method and L3 VLAN
Ensure that the interface connected to the grandmaster clock is configured as a slave device with a list of master clock IP
addresses. Configure the other interface as a master clock with a list of slave device IP addresses. Both the interfaces are only
reachable through the L3 VLAN.
In this example:
● Interface 1 that is part of VLAN 100 is connected to the grandmaster clock.
● The grandmaster clock is reachable only through VLAN 100.
● Interface 2 that is part of VLAN 200 is connected to the slave device.
● The slave device is reachable only through VLAN 200.
