[英]How to get current running ethernet speed from LabWindows\CVI C code or CMD commands
I am developing Test Equipment which has couple of Ethernet ports. 我正在开发具有几个以太网端口的测试设备。 As part of the testing i want to check the current speed of the ethernet ports (10/100/1000) when a tested unit is connected.
作为测试的一部分,我想在连接被测设备时检查以太网端口的当前速度(10/100/1000)。
How can i get this information? 我如何获得此信息? is there a C library or CMD command which i can use that can supply this information?
我可以使用可以提供此信息的C库或CMD命令吗?
C# is probably quicker to get up and running than API access with c/c++. 与使用c / c ++进行API访问相比,C#的建立和运行速度可能更快。
Try using the System.Net.NetworkInformation classes. 尝试使用System.Net.NetworkInformation类。 In particular,
System.Net.NetworkInformation.IPv4InterfaceStatistics
ought to have some information along the lines of what you're looking for. 特别是,
System.Net.NetworkInformation.IPv4InterfaceStatistics
应该具有与您所寻找内容System.Net.NetworkInformation.IPv4InterfaceStatistics
信息。
Specifically, you can check the bytesReceived
property, wait a given interval, and then check the bytesReceived
property again to get an idea of how many bytes/second your connection is processing. 具体来说,您可以检查
bytesReceived
属性,等待给定的时间间隔,然后再次检查bytesReceived
属性以了解连接正在处理多少字节/秒。 To get a good number, though, you should try to download a large block of information from a given source, and check then; 但是,要获得一个好的数字,您应该尝试从给定的源下载大量信息,然后进行检查; that way you should be 'maxing' the connection when you do the test, which should give more helpful numbers.
这样一来,您在进行测试时就应该“最大化”连接,这将提供更多有用的数字。
You need a linux running machine for the code to work You need to use the SIOCETHTOOL ioctl()
call in Linux. 您需要一台Linux运行机器才能使代码正常工作。您需要在Linux中使用
SIOCETHTOOL ioctl()
调用。
#include <stdio.h>
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <netinet/in.h>
#include <linux/sockios.h>
#include <linux/if.h>
#include <linux/ethtool.h>
#include <string.h>
#include <stdlib.h>
int main (int argc, char **argv)
{
int sock;
struct ifreq ifr;
struct ethtool_cmd edata;
int rc;
sock = socket(PF_INET, SOCK_DGRAM, IPPROTO_IP);
if (sock < 0) {
perror("socket");
exit(1);
}
strncpy(ifr.ifr_name, "eth0", sizeof(ifr.ifr_name));
ifr.ifr_data = &edata;
edata.cmd = ETHTOOL_GSET;
rc = ioctl(sock, SIOCETHTOOL, &ifr);
if (rc < 0) {
perror("ioctl");
exit(1);
}
switch (ethtool_cmd_speed(&edata)) {
case SPEED_10: printf("10Mbps\n"); break;
case SPEED_100: printf("100Mbps\n"); break;
case SPEED_1000: printf("1Gbps\n"); break;
default: printf("Speed returned is %d\n", edata.speed);
}
return (0);
}
I'm not sure about the Windows .May be you can refer here: Microsoft Developer Network 我不确定Windows。可能您可以在这里参考: Microsoft Developer Network
use wmic
command like this 使用这样的
wmic
命令
wmic PATH Win32_NetworkAdapter WHERE "PhysicalAdapter = TRUE AND NetEnabled = TRUE" GET Name, Speed
