You should make sure the sfptpd interface is configured to meet
network requirements. One method is to create the interface config file which is picked
up by the network service from the network-scripts
directory. For example:
# cat /etc/sysconfig/network-scripts/ifcfg-enp4s0f0
DEVICE="enp4s0f0"
TYPE="Ethernet"
BOOTPROTO="none"
ONBOOT="yes"
HWADDR="00:0f:53:1a:3b:4c"
IPADDR="172.11.123.123"
PREFIX=24
DEFROUTE="yes"
UUID="04426332-5e84-45fd-ad70-17c8790c99a9"
