On my system your command autoloads the sch_red
module. The question is rather old so on a modern system the autoloading should work fine if you have the required module. Check if you miss the kernel module by running:
在我的系统上,您的命令会自动加载sch_red
模块。这个问题相当古老,因此在现代系统上,如果您有所需的模块,自动加载应该可以正常工作。通过运行以下命令检查您是否错过了内核模块:
modprobe sch_red
If it prints nothing, then retry running tc
command and see if it helps.
如果它什么也没打印,然后重试运行tc
命令,看看它是否有帮助。
If not, ensure you have CONFIG_NET_SCH_RED
(Random Early Detection) compiled in your kernel. More info at kernel documentation.
如果没有,请确保您CONFIG_NET_SCH_RED
在内核中编译了(随机早期检测)。内核文档中的更多信息。
