[大数据]Setting the Marvell mv88e6190 switch with i.MX6 via rgmii interface [MAC to MAC layer]

[1] Adding TxC and RxC clock skew

[4] Configure the switch to be a bridge

ip link set eth0 up
ip link set lan1 up
ip link set lan2 up
ip link set lan3 up
ip link set lan4 up
ip link set lan5 up
ip link add name br0 type bridge
ip link set br0 up
ip link lan1 master br0
ip link lan2 master br0
ip link lan3 master br0
ip link lan4 master br0
ip link lan5 master br0
ip addr add 192.168.1.4/24 dev br0

linux中的 ip addr 和 ip link命令详解
一、ip addr命令
我是使用的linux系统是redhat7.3，其它linux的相关操作大同小异(在这里不做赘述)

1.查看

(1). ip addr 的缩写是ip a ，可以查看网卡的ip、mac等，?

即使网卡处于down状态，也能显示出网卡状态，但是ifconfig查看就看不到。

(2).ip addr show device ?查看指定网卡的信息

比如查看网卡接口的信息，就是ip addr show eth0

?
2.增加ip

ip addr add ip/netmask dev 接口

比如给eth0增加一个172.25.21.1/24 地址

ip addr add 172.25.21.1/24 dev eth0

3.删除ip

ip addr del ip/netmask dev 接口 ??

4.清空指定网卡的所有ip

ip addr flush dev 接口 ? ? ? ?

?5. 给网卡起别名，起别名相当于给网卡多绑定了一个ip ?

?用法： 比如给网卡eth0增加别名 ? ? ? ? ? ? ? ?

?ip addr add 172.25.21.1/32 dev eth0 label eth0:1

?6.删除别名 ? ? ? ? ? ? ?

?ip addr del ip/netmask dev eth0?

注意:

使用命令的方式设置别名，重启服务就没了，若要永久生效，

需要写配置文件，步骤如下：

1、确保NetworkManager服务是停止的

? ? systemctl stop NetworkManager ? ?关闭该服务?

? ? systemctl disable NetworkManager ?开机不自启动

? ?注意：

使用命令的方式增加或者删除ip，都是临时的，

如果重启network服务，那么操作就失效了。

想要永久生效可以修改配置文件ifcfg-eth0

二、ip link ?命令
?1.查看

? ip link只能看链路层的状态，看不到ip地址

?2.启用、禁用接口

? ip link set device down ? 禁用指定接口

? ip link set device up ? ?启用指定接口

? 比如禁用eth0就是ip link set eth0 down

说明：

? ? ip link不支持tab键补齐
