当我尝试删除任何规则或创建任何规则时出现 tc流量控制错误“tc：命令行不完整”

编程问答 2022-05-30

问题描述

我使用的是带有以下 Linux Open Industrial Linux 版本的 NXP 板 TQMLS1028A

$ cat /etc/os-realease
NAME=OpenIL
VERSION=2018.12
ID=OpenIL
VERSION_ID=2018.12
PRETTY_NAME="OpenIL 2018.12"

当我尝试使用命令删除任何界面中的规则时

[root@OpenIL:~]# tc qdisc delete dev enp0s0f0 root

输出是这个

tc: command line is not complete,try "help"

此外，如果我尝试制定这样的新规则

tc qdisc add dev enp0s0f0 parent root handle 100 taprio num_tc 2 map 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 queues 0@0 1@1 base-time 1554445635681310809 sched-entry S 01 500000 sched-entry S 02 500000 clockid CLOCK_TAI

即使我使用 replace 而不是添加，我也会得到以下输出，我得到相同的输出

tc: invalid argument 'root' to 'command'

知道我做错了什么吗？或者为什么我不能添加或删除任何规则？

以下输出是命令tc qdisc show

[root@OpenIL:~]# tc qdisc show

也许这会有所帮助
