Mii-tool-help

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

-V,-- version display version information displays version information

-v,-- verbose more verbose output displays information about the network interface

-R,-- reset reset MII to poweron state resets MII to on

-r,-- restart restart autonegotiation restart autonegotiation mode

-w,-- watch monitor for link status changes to view changes in the status of network interface connections

-l,-- log with-w, write events to syslog writes events to the system log

-A,-- advertise=media,... Advertise only specified media directs specific network interfaces

-F,-- force=media force specified media technology changes the negotiation mode of network interface

Media: 1000baseTx-HD, 1000baseTx-FD

100baseT4, 100baseTx-FD, 100baseTx-HD

10baseT-FD, 10baseT-HD

(to advertise both HD and FD) 1000baseTx, 100baseTx, 10baseT change the working mode of the network card, enter the command:

[root@10.10.90.97] # mii-tool-f media [interface]

Media: 1000baseTx-HD, 1000baseTxFD FDD, 100baseTx-FD, 100BasTxMelody HDpr 10BasTlue FD, 10baseT-HD

Interface: represents the selected network card, such as eth0,eth2. Default is eth2 instance 1: view the working mode of the network card.

[root@10.10.90.97] # mii-tool-v eth0

Eth0: negotiated 1000baseT-FD flow-control, link ok

Product info: vendor 00:50:ef, model 60 rev 8

Basic mode: autonegotiation enabled

Basic status: autonegotiation complete, link ok

Capabilities: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD

Advertising: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control

Link partner: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD

The above shows that the network card works in 1000m full-duplex adaptive mode, and "1000basetx-fd" means 1000m full duplex instance 2: set the network card to work in 100m half-duplex mode

[root@10.10.90.97 ~] # mii-tool-f 100baset-hd eth0 instance 3: restore the adaptive working mode of the network card

[root@10.10.90.97] # mii-tool-r eth0
