华为CE6800交换机堆叠配置案例
新到了2台华为CE6857交换机， 需要配置堆叠
硬件型号：CE6857F-48S6CQ
示例拓扑：
实际物理拓扑
配置思路
采用如下的思路配置：
- 提前规划好堆叠方案。
- 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。
- 连接交换机之间的堆叠线缆，然后将交换机上电。
- 检查堆叠组建是否成功。
操作步骤
1 提前规划堆叠方案。
规划SwitchA的堆叠成员ID为1，SwitchB的成员ID为2。
规划SwitchA作为主交换机，其堆叠优先级最高，为150。SwitchB的堆叠优先级为120。
规划堆叠域编号（Domain ID）为10，不与网络中其他堆叠系统的域编号冲突。
规划SwitchA和SwitchB用于堆叠连接的端口为100GE1/0/1～100GE1/0/2。
2 配置堆叠属性。
配置SwitchA的堆叠优先级为150，Domain ID为10。缺省情况下，设备的堆叠成员ID为1。此处默认SwitchA的堆叠成员ID为1，无需配置。
<HUAWEI> system-view
[~HUAWEI] sysname SwitchA
[*HUAWEI] commit
[~SwitchA] stack
[~SwitchA-stack] stack member 1 priority 150
Info: The operation will take effect after reboot.
[*SwitchA-stack] stack member 1 domain 10
Info: The operation takes effect only after the save command is executed. The device with a lower priority then will be reset in the stack merging scenario.
[*SwitchA-stack] quit
[*SwitchA] commit
** 配置SwitchB的堆叠成员ID为2，优先级为120，Domain ID为10。**
<HUAWEI> system-view
[~HUAWEI] sysname SwitchB
[*HUAWEI] commit
[~SwitchB] stack
[~SwitchB-stack] stack member 1 priority 120
Info: The operation will take effect after reboot.
[*SwitchB-stack] stack member 1 domain 10
Info: The operation takes effect only after the save command is executed. The device with a lower priority then will be reset in the stack merging scenario.
[*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
[*SwitchB-stack] quit
[*SwitchB] commit
说明：
由于SwitchB尚未重启，当前堆叠成员ID为1，此时需要使用member 1来进行堆叠配置。
Switch B使用stack member 1 renumber 2 inherit-config命令修改堆叠成员ID时，需要指定inherit-config参数。
如果不指定inherit-config参数，member 2不会继承member 1的堆叠配置，需要使用member 2重新进行堆叠配置。
指定inherit-config参数后，member 2可直接继承member 1的堆叠配置。
3 配置堆叠端口
配置堆叠端口。
将SwitchA的业务口100GE1/0/1～100GE1/0/2加入堆叠端口1/1。
[~SwitchA] interface stack-port 1/1
[*SwitchA-Stack-Port1/1] port member-group interface 100ge 1/0/1 to 1/0/2
Warning: After the configuration is complete,
1.The interface(s) (100GE1/0/1-1/0/2) will be converted to stack mode and be configured with the port crc-statistics trigger error-down command if the configuration does not exist.
2.The interface(s) may go Error-Down (crc-statistics) because there is no shutdown configuration on the interfaces.Continue? [Y/N]: y
[*SwitchA-Stack-Port1/1] commit
[~SwitchA-Stack-Port1/1] return
被配置为堆叠物理成员端口后，端口下会自动配置port crc-statistics trigger error-down。
将SwitchB的业务口100GE1/0/1～10GE1/0/2加入堆叠端口1/1。
[~SwitchB] interface stack-port 1/1
[*SwitchB-Stack-Port1/1] port member-group interface 100ge 1/0/1 to 1/0/2
Warning: After the configuration is complete,
1.The interface(s) (100GE1/0/1-1/0/2) will be converted to stack mode and be configured with the port crc-statistics trigger error-down command if the configuration does not exist.
2.The interface(s) may go Error-Down (crc-statistics) because there is no shutdown configuration on the interfaces.Continue? [Y/N]: y
[*SwitchB-Stack-Port1/1] commit
[~SwitchB-Stack-Port1/1] return
4 检查堆叠配置信息。
上述配置完成后，执行命令display stack configuration查看配置是否与规划的一致，如果不一致，需要修改配置。以查看SwitchA为例。
<SwitchA> display stack configuration
Oper : Operation
Conf : Configuration
* : Offline configuration
Isolated Port : The port is in stack mode, but does not belong to any Stack-Port
Attribute Configuration:

5 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。

6 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。
7 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。
<SwitchA>display stack

MemberID Role MAC Priority DeviceType Description

2 Standby e4dc-ccc3-08f0 120 CE6857F-48S6CQ
--------------------------------------------------------------------------------
如上所示，显示两台交换机的信息，表示堆叠建立成功，且主交换机为成员ID为1的设备，即SwitchA。
查看堆叠系统拓扑信息。
