NOTE: The PTP role is set to dynamic by default. If the role is set to dynamic, PTP uses the BMCA to select the master or slave role. Configure the PTP delay mechanism While measuring the time delay between the master and slave nodes, PTP takes into account the communication delay. This delay is measured using a delay request message from the slave and a delay response message from the master. To configure PTP delay mechanism: OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ptp delay-mechanism end-to-end Configure the PTP transport Supported PTP transport methods include Layer2 (ethernet), IPv4 (unicast and multicast), and IPv6 (unicast and multicast). Unicast transport method avoids flooding multicast messages in the network. OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ptp transport ipv4 unicast master Configure slave devices for a master clock device You can configure the IP addresses of multiple slave devices. To configure slave devices for the master clock device: OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ptp transport ipv4 unicast master OS10(conf-ethernet1/1/1-ptp-ipv4-master)# slave 10.10.10.1 OS10(conf-ethernet1/1/1-ptp-ipv4-master)# slave 10.10.10.2 Configure a source for unicast transport from a master clock device to a slave clock device You must configure a source IP address for unicast transport from a master clock device to a slave clock device. OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ptp transport ipv4 unicast master OS10(conf-ethernet1/1/1-ptp-ipv4-master)# source 10.10.10.2 NOTE: If you are configuring PTP on an OS10 switch that functions as a virtual router, configure the local IP address as the source IP address for UNICAST TRANSPORT mode. Do not configure the virtual IP address as the source IP address. Configure master clock devices for a slave clock device You can configure the IP addresses of multiple master clock devices. OS10 supports configuring a maximum of eight master clock devices. OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ptp transport ipv4 unicast slave OS10(conf-ethernet1/1/1-ptp-ipv4-slave)# master 10.10.10.1 OS10(conf-ethernet1/1/1-ptp-ipv4-slave)# master 10.10.10.2 Configure a source for unicast transport from a slave clock device to a master clock device You must configure a source IP address for unicast transport from a slave clock device to a master clock device. OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ptp transport ipv4 unicast slave OS10(conf-ethernet1/1/1-ptp-ipv4-slave)# source 10.10.10.2 NOTE: If you are configuring PTP on an OS10 switch that functions as a virtual router, configure the local IP address as the source IP address for UNICAST TRANSPORT mode. Do not configure the virtual IP address as the source IP address. Configure a PTP VLAN You can configure a VLAN on a PTP-enabled interface. If you configure a VLAN on the grandmaster clock, the grandmaster clock can drop untagged packets. If the VLAN tagged in a packet is the same as the PTP VLAN, the VLAN tagged packets are received on the PTP interface. Untagged packets are accepted on the PTP interface. OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ptp vlan 10 172 System management
