@jordanm이 언급했듯이 이더넷 포트입니다.
다음은 포트의 명명 규칙입니다.
enp4s10f1 pci 0000:04:0a.1
| | | | | | | |
| | | | domain <- 0000 | | |
| | | | | | |
en| | | --> ethernet | | |
| | | | | |
p4| | --> prefix/bus number (4) <-- 04 | |
| | | |
s10| --> slot/device number (10) <-- 10 |
| |
f1 --> function number (1) <-- 1
네트워킹 세계에서 "비활성화" 또는 "비활성화" 포트라고 부르는 현상이 발생하고 있습니다. 여기에서 볼 수 있듯이 state DOWN포트는 여전히 물리적으로 사용 가능하고 전력을 소비하지만 소프트웨어 수준에서는 트래픽 전달이 금지되어 있습니다. 안타깝게도 Linux에서 포트를 완전히 종료하는 유일한 방법은 해당 포트의 드라이버를 제거하는 것입니다. 이 경우 사용되지 않는 포트는 전력을 거의 소비하지 않으므로 전원을 완전히 끄려고 시간을 들일 가치가 없습니다.
