linux 下檢視網卡工作速率
Ethtool是用于查詢及設定網卡參數的指令。
概要:
ethtool ethX //查詢ethX網口基本設定
ethtool –h //顯示ethtool的指令幫助(help)
ethtool –i ethX //查詢ethX網口的相關資訊
ethtool –d ethX //查詢ethX網口注冊性資訊
ethtool –r ethX //重置ethX網口到自适應模式
ethtool –S ethX //查詢ethX網口收發包統計
ethtool –s ethX [speed 10|100|1000]\ //設定網口速率10/100/1000M
[duplex half|full]\ //設定網口半/全雙工
[autoneg on|off]\ //設定網口是否自協商
使用ethtool,結果如下:
[root@hadoop009 var]# ethtool em1
