PTP role is dynamic by default. For multicast transport mode, when you enable PTP, the system sends a join message.
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ptp transport ipv4 multicast
OS10(conf-if-eth1/1/1)# ptp enable
4. Enable PTP on interface 2 with IPv4 multicast transport mode.
PTP role is dynamic by default. For IPv4, multicast is the default transport mode.
OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# ptp transport ipv4 multicast
OS10(conf-if-eth1/1/2)# ptp enable
Interface 1 becomes the slave device and interface 2 becomes the master clock for other devices.
Example: Configure boundary clock with IPv4 unicast transport
method
Ensure that you configure the interface connected to the grandmaster clock as a slave device with a list of master device IP
addresses. Configure the other interface as the master device with a list of slave device IP addresses. In this example, the
grandmaster clock is connected to interface 1.
Configure a boundary clock with two PTP interfaces using IPv4 unicast transport. Use unicast
transport mode when you have clearly defined the role of each node in your deployment.
1. Configure the PTP boundary clock.
The delay mechanism of the boundary clock is end-to-end by default.
OS10(config)# ptp clock boundary
2. Enable PTP on interface 1 with IPv4 unicast transport mode.
For L3 interface, if you have not configured the source IP address, the interface IP address is used as the source IP address
for unicast transport from the slave device to the master device.
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ip address 10.10.10.1/24
OS10(conf-if-eth1/1/1)# ptp transport ipv4 unicast slave
OS10(conf-ethernet1/1/1-ptp-ipv4-slave)# master 10.10.10.2
OS10(conf-ethernet1/1/1-ptp-ipv4-slave)# exit
OS10(conf-if-eth1/1/1)# ptp enable
3. Enable PTP on interface 2 with IPv4 unicast transport mode.
