[LINUX] 리눅스에서 NIC Slot 위치 찾기

리눅스에서 사용하고 있는 Device(ethX, ensX)의 슬롯 위치를 찾기위해 lshw 명령어를 사용하면 찾기가 쉬워진다. 

lshw 명령은 설치 기본 설치이미지의 ISO파일에 포함이 되어있다 먼저 패키지를 설치하고 명령어로 확인해보자 

 

NIC Device name 별 bus 주소확인

lshw명령으로 Device 별 버스정보를 먼저 확인 한다.

위와 같이 dmidecode 명령으로 버스주소에 해당되는 위치의 슬롯 번호를 확인하면 Device에 대한 슬롯위치를 확인할 수 있다.
