本次采用软硬件：
硬件：CE6881-48S6CQ
软件：VRP (R) software, Version 8.191 (CE6881 V200R019C10SPC800)
组网：
配置思路：
1. 提前规划好堆叠方案。
2. 按照前期的规划，完成各台交换机的堆叠配置，包括堆叠成员ID、堆叠优先级、堆叠域编号、堆叠端口等。完成后保存配置并将交换机下电。
3. 连接交换机之间的堆叠线缆，然后将交换机上电。
4. 检查堆叠组建是否成功。
SwitchA配置：
[~HUAWEI]sysname SwitchA
[*HUAWEI]commit
[~SwitchA]stack
[~SwitchA-stack]stack member 1 priority 120
[~SwitchA-stack]stack member 1 domain 10
[*SwitchA-stack]qu
[*SwitchA]commit
[~SwitchA]interface Stack-Port 1/1
[*SwitchA-Stack-Port1/1]port member-group interface 100GE 1/0/1
Warning: After the configuration is complete,
1.The interface will be configured with the port crc-statistics trigger error-down command.
2.The interface may go Error-Down (crc-statistics) because of no shutdown configuration.Continue? [Y/N]:y

[*SwitchA]interface Stack-Port 1/2
[*SwitchA-Stack-Port1/2]port member-group interface 100GE 1/0/4
Warning: After the configuration is complete,

2.The interface may go Error-Down (crc-statistics) because of no shutdown configuration.Continue? [Y/N]:y

SwitchB配置：
[~HUAWEI]sysname SwitchB
[*HUAWEI]commit
[~SwitchB]stack
[~SwitchB-stack]stack member 1 priority 90
[~SwitchB-stack]stack member 1 domain 10
[*SwitchB-stack]stack member 1 renumber 2 inherit-config
Warning: The stack configuration of member ID 1 will be inherited to member ID 2 after the device resets. Continue? [Y/N]:y
Info: The operation will take effect after reboot.

保存配置后将设备下电。
保存SwitchA和SwitchB的配置，然后将设备下电。SwitchB的配置与SwitchA相同，略。
连接线缆
按照前期规划及配置，连接堆叠线缆。线缆连接完成后将设备上电。
建议先将高优先级设备上电，以使其先完成启动，优先竞争为主交换机。
验证配置结果。
等待几分钟后，在主交换机SwitchA上使用命令display stack查看堆叠是否组建成功。
