查看linux系統網卡工作模式、速率等   有時候,我們需要看下linux系統網卡工作模式、速率等,比較常 用到的命令是mii-tool、ethtool,下面簡單看下即可。   www.2cto.com   查看下eth0網卡信息 [root@cloud ~]# mii-tool -v eth0 eth0: negotiated 100baseTx-FD flow-control, link ok product info: vendor 00:00:20, model 32 rev 1 basic mode: autonegotiation enabled basic status: autonegotiation complete, link ok capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD advertising: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control   從上面可以看出eth0 工作 100M全雙工自適應模式下 [root@cloud ~]# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Link partner advertised pause frame use: Symmetric Receive-only Link partner advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) Link detected: yes [root@cloud ~]#
