S5720交换机，做下堆叠，两条线，交叉互联（即A交换机23口连到B交换机24口，A交换机24口连接B交换机23口）。
改名
[Huawei]sysname SWA
最好先shutdown接口
[SWA]interface GigabitEthernet 0/0/23 [SWA-GigabitEthernet0/0/23]shutdown [SWA-GigabitEthernet0/0/23]interface GigabitEthernet 0/0/24 [SWA-GigabitEthernet0/0/24]shutdown [SWA-GigabitEthernet0/0/24]quit
SWA默认number0
[SWA]interface stack-port 0/1
[SWA-stack-port0/1]port interface GigabitEthernet 0/0/23 enable
[SWA-stack-port0/1]quit
[SWA]interface stack-port 0/2
[SWA-stack-port0/2]port interface GigabitEthernet 0/0/24 enable
[SWA-stack-port0/2]quit
开启23和24接口，保存配置
[SWA]interface GigabitEthernet 0/0/23 [SWA-GigabitEthernet0/0/23]undo shutdown [SWA-GigabitEthernet0/0/23]interface GigabitEthernet 0/0/24 [SWA-GigabitEthernet0/0/24]undo shutdown [SWA-GigabitEthernet0/0/24]quit [SWA]quit <SWA>save The current configuration will be written to the device. Are you sure to continue?[Y/N]y Info: Please input the file name ( *.cfg, *.zip ) [vrpcfg.zip]: Now saving the current configuration to the slot 0. Save the configuration successfully. ————————————————
改名
[Huawei]sysname SWB
关闭接口
[SWB]interface GigabitEthernet 0/0/23 [SWB-GigabitEthernet0/0/23]shutdown [SWB-GigabitEthernet0/0/23]interface GigabitEthernet 0/0/24 [SWB-GigabitEthernet0/0/24]shutdown [SWB-GigabitEthernet0/0/24]quit
修改成员号
[SWB]stack slot 0 renumber 1
默认100，华为是1-255，值越大优先级越高会被推举为Master
[SWB]stack slot 0 priority 10
[SWB]interface stack-port 0/1
[SWB-stack-port0/1]port interface GigabitEthernet 0/0/23 enable
[SWB-stack-port0/1]quit
[SWB]interface stack-port 0/2
[SWB-stack-port0/2]port interface GigabitEthernet 0/0/24 enable
[SWB-stack-port0/2]quit
开启23和24接口，保存配置
[SWB]interface GigabitEthernet 0/0/23 [SWB-GigabitEthernet0/0/23]undo shutdown [SWB-GigabitEthernet0/0/23]interface GigabitEthernet 0/0/24 [SWB-GigabitEthernet0/0/24]undo shutdown [SWB-GigabitEthernet0/0/24]quit [SWB]quit <SWB>sava The current configuration will be written to the device.

补充：
[SwitchA] stack slot 0 priority 200 //修改主交换机的堆叠优先级为200，大于其他成员交换机。堆叠ID采用缺省值0。
[SwitchB] stack slot 0 renumber 1 //堆叠优先级采用缺省值100。修改堆叠ID为1。
[SwitchC] stack slot 0 renumber 2 //堆叠优先级采用缺省值100。修改堆叠ID为2。
