我一辈子都无法在 SRX 上获得任何出口队列优先级。

我有一个从 SRX 出来的标签交换路径，还有几个以太网 CCC。一个ccc完全是加急转发，另一个完全是尽力而为。

我在接口节上有输入过滤器来设置两个 ccc 的转发类。然后我可以在标签交换路径上应用监管过滤器来限制相应电路的速率。

此时，如果我设置监管使 BE 流量限制为 9Mb，EF 流量限制为 1Mb，那么一切都按我的意愿运行。然而....

我只想在标签交换路径上监管 EF 电路，并让 BE 电路全开，但确保 EF 流量可以优先达到其监管限制。

我整天都在玩转发类，无济于事。开始认为那不是我应该寻找的地方？

这是我在这里转发课程的尝试：
