Some commands about bandwidth MTU in Linux

to view negotiated bandwidth sizes

sudo ethtools eth0

Linux change the NIC MTU method:

1. Open Terminal , view current network card settings: ifconfig

650) this.width=650; "src="/e/u261/themes/default/images/spacer.gif "style=" Background:url ("/e/u261/lang/zh-cn/ Images/localimage.png ") no-repeat center;border:1px solid #ddd;" alt= "Spacer.gif"/>650 "this.width=650;" src= "http ://s4.51cto.com/wyfs02/m02/8b/79/wkiol1hpcjohtki0aafnm9vkqei917.png-wh_500x0-wm_3-wmp_4-s_3215724699.png "title = "2.png" alt= "Wkiol1hpcjohtki0aafnm9vkqei917.png-wh_50"/>

2. Set the NIC for which you want to change the MTU (you need to figure out which NIC it is), such as Eth0:sudo ifconfig eth0 MTU 1600

The MTU setting is viewed again via ifconfig after the change is complete

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/8B/79/wKioL1hPcl3C8x_jAAGI55R8uwE966.png "title=" 1.png " alt= "Wkiol1hpcl3c8x_jaagi55r8uwe966.png"/>

Note: This method is a temporary change, such as a system restart or a network service restart will fail!

As a result of the MTU setting, the MTU setting can be written to the NIC configuration to automatically set when the hardware is loaded.
