linuxptp进行两个设备时间戳同步的过程中，我分别通过git和通过终端apt install了linuxptp的软件，在本机的调试中运行ptp4l -i eno1 -m -S时在终端中得到了如下反馈：
ptp4l[4173.699]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[4173.700]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[4173.700]: port 1: link down
ptp4l[4173.700]: port 1: LISTENING to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED)
ptp4l[4173.700]: selected local clock 902e16.fffe.6af5e0 as best master
ptp4l[4173.700]: assuming the grand master role
ptp4l[4173.700]: port 1: master state recommended in slave only mode
ptp4l[4173.700]: port 1: defaultDS.priority1 probably misconfigured
随后在另外2台设备上运行，均发现网口port1存在以上的信息，随后我按照一篇如下帖子进行了操作：

在最后 sudo systemctl status ptp4l的返回中有如下信息：

想请问这里的failed该如何解决呢
这里的failed可能是由于ptp4l.conf文件中的配置有误导致的，可以尝试检查一下ptp4l.conf文件中的配置是否正确，或者尝试重新安装linuxptp软件，看看是否能够解决这个问题。
