# 执行以太网操作 您可以执行以下基本操作，例如配置地址、查看链路状态、监控连接以及使用各种工具调试连接故障。 Tab QCS6490 Tab IQ-9075 Tab IQ-8275 Tab IQ-615 - *class* tabincludedirective - ## 检查数据连接 使用 `ping` 命令检查设备接口与远程连接接口之间的连接。 Note 客户端 IP 地址必须与设备 IP 地址在同一网段。 `ping` 命令的示例输出用于检查从 RB3 Gen 2 开发套件到主机 PC 的网络连接。 ping 169.254.227.240 PING 169.254.227.240 (169.254.227.240) 56(84) bytes of data. 64 bytes from 169.254.227.240: icmp_seq=1 ttl=64 time=1.45 ms
