5.2. 如何使用双以太网
Android 双以太网口分内网和外网。
| 硬件设备名 | dts 节点 | Android 系统设备名 | 主副关系 |
|---|---|---|---|
| eth0 | gmac1 | Ethernet 2 | 副网口，用于内网 |
| eth1 | gmac0 | Ethernet | 主网口，用于外网 |
5.2.1. 查看IP地址
-
双以太网口接入网络，可以通过调试串口或者adb来查看IP地址，比如
ifconfig eth0eth0 Link encap:Ethernet HWaddr 36:0a:d2:60:c9:05 Driver rk_gmac-dwmacinet addr:168.168.101.68 Bcast:168.168.255.255 Mask:255.255.0.0inet6 addr: fe80::3290:2dc:3624:1dec/64 Scope: LinkUP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1RX packets:15804 errors:0 dropped:1 overruns:0 frame:0TX packets:68 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:1811566 TX bytes:6748Interrupt:75ifconfig eth1eth1 Link encap:Ethernet HWaddr 32:0a:d2:60:c9:05 Driver rk_gmac-dwmacinet addr:168.168.101.38 Bcast:168.168.255.255 Mask:255.255.0.0inet6 addr: 240e:3b1:f174:f00:d3fe:4d8e:fda9:3c0/64 Scope: Globalinet6 addr: fe80::b556:9d3f:e684:bec4/64 Scope: Linkinet6 addr: 240e:3b1:f174:f00:9d78:e75f:6167:15c1/64 Scope: GlobalUP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1RX packets:913 errors:0 dropped:1 overruns:0 frame:0TX packets:210 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:108473 TX bytes:24906Interrupt:127
