华三交换机irf堆叠配置实验

华三交换机irf堆叠配置实验

配置如下：

通过堆叠我们将四台交换机堆叠为一台交换机，其中设置第一台为主交换机，优先级为32，所以其他的从交换机配置都会被主交换机覆盖，四台堆叠成一台交换机后的配置如下：

现在配置irf （注意配置前需要将堆叠线拆除）

首先我们先确认一些信息 使用的堆叠口为XG1/0/51 到 XG1/0/52

左边的设备设置member 号为1使用irf端口1-1

右边的设备设置member 号为2使用irf端口2-2

左边的设备irf优先级为32作为主设备，

右边的设备irf优先级为1作为备用设备

配置交换机时候会用到的命令如下
[sw1]irf member 1 priority 32 //设置优先级为32

memberid就是设备的member号，member号决定了端口号
[sw2]irf member 1 renumber 2 //交换机的端口命名格式： 接口类型/ 框号/插槽号/端口号当member号发生改变时，对应端口的框号就会发送改变
[sw1]quit
<sw1>reboot
此时重启完设备后irf 成员id就会变成2
我们查看下重启后的irf信息，发现irf成员id变成2

此时我们可以看到有两个设备了，
一个的member id 为1 优先级为32 是（master）主设备
另一个的member id 为2 优先级为1 是(standby)备用设备
星号标识的是master（主设备）
加号标识的是当前登陆的设备
也就是说我们当前登陆的左边的这台交换机是主设备
我们再来看 下是否能在左边设备上看到右边设备上的端口
