Dell EMC SmartFabric OS10 User Guide Release 10.5.1

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.

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.
   • The interface is a trunk port.
   • A source address is configured for unicast transport from the slave device to the master clock device.
   • The unicast IP traffic flows through the PTP-enabled interface and reaches the destination. The system applies hardware time stamps on PTP packets.

   OS10(config)# interface vlan 100
   OS10(conf-if-vl-100)# ip address 10.10.10.1/24
   
   OS10(config)# interface ethernet 1/1/1
   OS10(conf-if-eth1/1/1)# switchport mode trunk
   OS10(conf-if-eth1/1/1)# switchport trunk allowed vlan 100
   OS10(conf-if-eth1/1/1)# ptp vlan 100
   OS10(conf-if-eth1/1/1)# ptp transport ipv4 unicast slave
   OS10(conf-ethernet1/1/1-ptp-ipv4-slave)# source 10.10.10.1
   OS10(conf-ethernet1/1/1-ptp-ipv4-slave)# master 10.10.10.2
   
   OS10(conf-if-eth1/1/1)# ptp enable

3. Enable PTP on interface 2 with IPv4 unicast transport mode.
   • The interface is an access port.
   • Configure a source IP address for unicast transport from the master device to the slave device.
   • The unicast IP traffic flows through PTP-enabled interface, interface 2. The system applies hardware time stamps on PTP packets.

   OS10(config)# interface vlan 200
   OS10(conf-if-vl-200)# ip address 20.20.20.1/24
   
   OS10(config)# interface ethernet 1/1/2
   
   OS10(conf-if-eth1/1/2)# switchport access vlan 200
   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-if-eth1/1/2)# ptp enable
