和：
我正在使用 G8316 作为带有ptp transparent enableMellanox 354 适配器的交换机。
使用 LACP 绑定和中继的端口。
第一：服务器Aptp4l -m -l 7 -i xxxx -i xxxx -S
我可以在 ServerB 上捕获 ServerA 的广播包，并且 G8316 交换机上的 ptp 计数器显示非零。这意味着 ptp 包已发送，这很好。
然后：服务器 Bptp4l -m -l 7 -i xxxx -i xxxx -S -s
服务器 B 无法找到服务器 A，并使用本地时钟作为最佳主时钟
问题：
- 为什么服务器A说
master sync timeout - 为什么服务器 B 固执地认为本地时钟是最好的主时钟
我也尝试使用配置文件设置优先级，主服务器为 0，从服务器为 255。没有作用。
