FedoraLinux system adjusts the Nic speed

Article title: FedoraLinux system adjusts the Nic speed. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

The following describes how to adjust the Nic speed in the Fedora Linux system. Some friends may have asked me how to adjust the Nic speed in the Fedora Linux system, hope to help you. Sometimes we need to adjust the speed of the NIC, which can be quickly set in Fedora.

Use mii-tool to quickly set the Nic speed

Command format: mii-tool [vVrRFwl] media [interface]

-V, -- verbose more verbose output displays network interface information;

-R, -- reset MII to poweron state resetting MII to enabled state;

-R, -- restart autonegotiation restart automatic negotiation mode;

-W, -- watch monitor for link status changes to view the status changes of network interface connections;

-L, -- log with-w, write events to syslog write events to system logs;

-A, -- advertise = media,... advertise only specified media instruction-specific network interface;

-F, -- force = media force specified media technology changes the speed of network interfaces;

Media:

100baseTx-FD, 100baseTx-HD, 10baseT-FD, 10baseT-HD

Interface indicates that the selected Nic is eth0 by default.

Instance:

Set the NIC to work in 10 m half duplex mode. enter the following command:

# Mii-tool-F 10baseT-HD eth0

To restore the adaptive working mode of the network adapter, run the following command:

# Mii-tool-r eth0
