[Linux] lshw를 통한 network 종류 확인방법

SR-IOV를 사용하다보면, 해당 인터페이스뒤에 v0 등으로 표시되면 좋은데 그렇지 않은 경우 물리NIC인지, VF 인지 확인하기 번거로울때가 있는데, 이때 "lshw -c network -businfo" 명령어를 통해 쉽게 network 종류를 확인할 수 있습니다.

 

확인하기 편한 예

4: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether e4:43:4b:b5:28:b0 brd ff:ff:ff:ff:ff:ff
    vf 0     link/ether 12:64:a4:b8:e1:f2 brd ff:ff:ff:ff:ff:ff, spoof checking on, link-state auto, trust off, query_rss off
    vf 1     link/ether ce:e9:dd:b9:86:d5 brd ff:ff:ff:ff:ff:ff, spoof checking on, link-state auto, trust off, query_rss off
