4. 每台设备上可以同时启动多个gPTP程序,但是不能存在多个gPTP master,否则会自动切换; root@DevelLinux:~# ifconfig eth0 192.168.200.101/24 up && ptp4l -i eth0 -f gPTP.cfg-m & # 设备1 root@DevelLinux:~# ifconfig eth0 192.168.200.102/24 up && ptp4l -i eth0 -f gPTP.cfg-m & # ...
用于gPTP模式判断Sync是否超时，是否触发best master clock选择。
默认配置：linuxptp的默认配置文件通常位于packages/rfs/yoctopoky/build/tmp/work/core264pokylinux/linuxptp/2.0r0/linuxptp3.1.1/configs/default.cfg。修改配置：删除gPTP.cfg中的neighborPropDelayThresh 800配置，并将修改后的配置文件下载至/home/root目录。执行测试命令：在两台设备上分别执行测试...
