BCM957810A1008G 10g linux 로그

꽂고 켠 김에 기록

 

장치는 제대로 잡힌건가 드라이버를 어떻게 확인해야 하지?

BCM957810A1008G <- 요게 모델로 알고 있는데 BCM 뒤에 9는 멀까..?

SR-IOV를 켜놓고 VT 안 켜서 켜고 끄고 해봤는데 bnx 관련으로 달라지는건 없다.

두개의 칩셋을 하나의 pciex 보드에 올린 유형인가 두번 초기화 하네?

커널 모듈에서는 아래와 같이 bnx2x 모듈로 로드되었고

$ lsmod | grep bnx bnx2x                1028096  0 mdio                   12288  1 bnx2x libcrc32c              12288  1 bnx2x

 

케이블을 바꾸어도 watch -n 0 으로 해서 0.2초 간격으로 봐도 저 놈의 link가 떨어지는게 보이지 않는다.

커널로그로도 없고 도대체 어디서 탐지하는거지?

FEC는 Forward Error Correction 의 약자라는데 먼가 CRC 보다 강해 보이는데

이해를 포기(!)
