[LINUX] 리눅스에서 NIC Slot 위치 찾기

by 양눈 2020. 12. 19.

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. 

#  lshw -c network -businfo
Bus info          Device      Class          Description
========================================================
pci@0000:03:00.0 ens0      network        I350 Gigabit Network Connection
pci@0000:03:00.1 ens1      network        I350 Gigabit Network Connection
pci@0000:03:00.2 ens2      network        I350 Gigabit Network Connection
pci@0000:03:00.3 ens3      network        I350 Gigabit Network Connection
pci@0000:05:00.0  eno1        network        OneConnect NIC (Skyhawk)
pci@0000:05:00.1  eno2        network        OneConnect NIC (Skyhawk)
pci@0000:05:00.2  eno3        network        OneConnect NIC (Skyhawk)
pci@0000:05:00.3  eno4        network        OneConnect NIC (Skyhawk)
