华为CE交换机堆叠故障问题
问题描述
两台CE6857F交换机通过堆叠部署后， 其中两台迁移机房后，原先四台堆叠变成了两两堆叠，为使设备再次进行堆叠，手动清空原有配置，重新为设备定义域名、槽号和优先级等配置信息，在检查配置信息无误的情况下提交并保存配置，然后按照主、备顺序重启设备，但是最终发现堆叠组还是无法建立。
告警信息
Failed to join the stack because local configuration conflicted with the master device's configuration. Run the "display stack troubleshooting" command to view detailed information.
处理过程
步骤一：
使用display stack troubleshooting命令查看堆叠故障事件信息。
<CE6857F>dis stac troubleshooting
The records are only about tracks of active and historical stack events.
Total :1
--------------------------------------------------------------------------------
Seq Time Event Description
--------------------------------------------------------------------------------
1 2025-02-27 15:11:01.162 Configuration conflict: The port is configured as
member port of Stack-Port on the local device, but
it is configured as a stack isolated port or a fa
bric member port on the master device. (Port(s) =
100GE2/0/5, 100GE2/0/6, Maste
rMAC = XXXX-d330-XXXX)
步骤二：
通过dis stack link-state last-down-reason命令查看堆叠口DOWN的原因。
<CE6857F>dis stack link-state last-down-reason
Stack-Port :
--------------------------------------------------------------------------------
Stack-Port : Stack-Port2/1
Stack-Port Protocol State : down
Member Port(s) State :
Down Reason : The Stack-Port does not have member interfaces.
根因
据以上信息分析，该问题因堆叠端口冲突导致堆叠无法创建，但是在清空原有堆叠配置，重新配置后设备始终无法创建堆叠组。
再次经过反复排查发现，因设备之前已创建好堆叠组，相关堆叠配置信息且已保存在内核系统中（一般情况下无法删除或更改配置）。
解决方案
1、拆分堆叠。
在全局模式下通过clear inactive-configuratio n all命令来清除离线设备的非激活配置信息。
[~E5_E6/CE6851_computing]clear inactive-configuration all
Warning: All inactive configurations will be deleted and can't be restored.
Are you sure to continue? [Y/N]:y
Info: Operating, please wait for a moment..................done.

2、查看现有堆叠配置
#display stack configuration --------------------------------------------------------查看堆叠配置
Oper : Operation
Conf : Configuration
* : Offline configuration
Isolated Port : The port is in stack mode, but does not belong to any Stack-Port
Attribute Configuration:
-----------------------------------------
MemberID Domain Priority
Oper(Conf) Oper(Conf) Oper(Conf)
-----------------------------------------
1(1) 10(10) 200(200)
2(2) 10(10) 150(150)
-----------------------------------------
Stack-Port Configuration:
--------------------------------------------------------------------------------
Stack-Port Member Ports
--------------------------------------------------------------------------------
Stack-Port1/1 40GE1/0/5 40GE1/0/6-----------------------------槽位1堆叠接口
Stack-Port2/2 40GE2/0/5 40GE2/0/6-----------------------------槽位2堆叠接口
--------------------------------------------------------------------------------
Isolated Port Configuration:
3、删除堆叠配置
步骤一：
#stack---------------------------------------------------------------进入堆叠管理视图
#display this--------------------------------------------------------查看系统当前视图运行配置
#
stack
#
stack member 1 domain 10-------------------------------------堆叠域编号
stack member 1 priority 200------------------------------------堆叠优先级
#
stack member 2 domain 10
stack member 2 priority 150
#
Return
#undo stack member 1 domain 10----------------------------删除配置
Info: The operation will take effect after reboot.
#undo stack member 1 priority 200----------------------------删除配置
Info: The operation will take effect after reboot.
#undo stack member 2 domain 10------------------------------删除配置
Info: The operation will take effect after reboot.
#undo stack member 2 priority 150--------------------------删除配置
Info: The operation will take effect after reboot.
步骤二：
#int Stack-Port 1/1---------------------------------------------------------进入堆叠端口
#undo port member-group interface 100GE 1/0/5 to 1/0/6------------剔除堆叠端口
#commit---------------------------------------------------------------------提交配置
#qui--------------------------------------------------------------------------退出
#save-------------------------------------------------------------------------保存配置
Warning: The current configuration will be written to the device. Continue? [Y/N]:y
Now saving the current configuration to the slot 1 .
Info: Save the configuration successfully.
步骤三：
#stack
#stack member 1 domain 10-------------------------------------------配置堆叠ID1域编号为10
#stack member 1 priority 200------------------------------------------配置堆叠ID1优先级为200
#int Stack-Port 1/1---------------------------------------------------------进入堆叠端口
#port member-group interface 100GE 1/0/5 to 1/0/6------------------添加堆叠端口
#commit---------------------------------------------------------------------提交配置
#qui--------------------------------------------------------------------------退出
#save-------------------------------------------------------------------------保存配置
Warning: The current configuration will be written to the device. Continue? [Y/N]:y
Now saving the current configuration to the slot 1 .
Info: Save the configuration successfully.
4、重启设备
