linux 查看网卡单双工,Linux 查看网卡全双工 还是半双工 以及设置网卡为半双工...

请问各位兄弟，在Linux中怎么看网卡是全双工工作还是半双工工作？

mii-tool

Linux:~ # mii-tool

eth0: no link

eth1: no autonegotiation, 100baseTx-HD, link ok

Linux:~ #

Linux:~ # mii-tool -F

mii-tool: option requires an argument -- F

usage: mii-tool [-VvRrwl] [-A media,... | -F media] [interface ...]

-V, --version display version information

-v, --verbose more verbose output

-R, --reset reset MII to poweron state

-r, --restart restart autonegotiation

-w, --watch monitor for link status changes

-l, --log with -w, write events to syslog

-A, --advertise=media,... advertise only specified media

-F, --force=media force specified media technology

media: 100baseT4, 100baseTx-FD, 100baseTx-HD, 10baseT-FD, 10baseT-HD,

(to advertise both HD and FD) 100baseTx, 10baseT

Linux:~ # mii-tool

eth0: no link

eth1: no autonegotiation, 100baseTx-HD, link ok

Linux:~ # mii-tool -F 100baseTx-HD

//切换网卡得状态为半双工状态

Linux:~ # mii-tool

eth0: 100 Mbit, half duplex, no link

eth1: 100 Mbit, half duplex, link ok
