Linux to see the network card operating rate

Ethtool is the command used to query and set the network card parameters.

Profile:
Ethtool ethx//Query Ethx the basic settings of the network port
ETHTOOL–H//Display command Help for Ethtool
Ethtool–i ethx//Query ETHX network port information
Ethtool–d ethx//Inquiry ETHX Network registration information
Ethtool–r ethx//Reset ETHX network port to Adaptive mode
Ethtool–s ethx//query ETHX network receipt and contract statistics
Ethtool–s ethx [Speed 10|100|1000]\//Set network port rate 10/100/1000m
[Duplex half|full]\//Set net port half/Full-duplex
[Autoneg on|off]\//Set the network port is self negotiated

Using Ethtool, the results are as follows:
