linux – 如何识别孤立的veth接口以及如何删除它们？

root@hostname /home # ifconfig | grep veth | wc -l
53
root@hostname /home # docker run -d -P  axibase/atsd -name axibase-atsd-
28381035d1ae2800dea51474c4dee9525f56c2347b1583f56131d8a23451a84e

我如何识别哪些接口与现有容器链接,以及如何删除与已删除的对手链接的额外接口？

这种方式不起作用(通过root)：

ifconfig veth55d245e down
brctl delbr veth55d245e
can't delete bridge veth55d245e: Operation not permitted

现在由传输流量定义的额外接口(如果没有活动,则是额外接口).
