组网需求

在一个新建的数据中心网络中，要求核心层具有较高的可靠性，并且希望网络结构简单，易于配置和管理。
如图4-1所示，根据用户需求，核心层SwitchA和SwitchB两台交换机采取堆叠组网。

配置思路

采用如下的思路配置：
1.提前规划好堆叠方案。
2.按照前期的规划，连接好SwitchA和SwitchB之间的堆叠线缆。
3.在SwitchA和SwitchB上进行堆叠软件配置，包括堆叠成员ID、堆叠优先级、堆叠域编号、堆叠连接方式、堆叠端口等。
4.保存SwitchA和SwitchB的配置，并使能堆叠功能。
5.检查堆叠组建是否成功。
6.配置双主检测。

操作步骤

1.提前规划堆叠方案。

规划的主要内容如表4-1所示。
表4-1 堆叠规划内容

2.连接堆叠线缆。

如图4-2所示，按照前期规划连接SwitchA和SwitchB之间的堆叠线缆。连接的端口包括主控板上的SIP口、业务板上的堆叠物理成员端口和双主检测端口。
图4-2 堆叠连接示意图

3.配置堆叠属性。

配置SwitchA的优先级为150，Domain ID为10。此处默认SwitchA的堆叠成员ID为1，堆叠连接方式为主控板直连方式，无需配置。

<HUAWEI> system-view
[~HUAWEI] sysname SwitchA
[*HUAWEI] commit
[~SwitchA] stack
[~SwitchA-stack] stack priority 150
[*SwitchA-stack] stack domain 10
[*SwitchA-stack] quit
[*SwitchA] commit

配置SwitchB的堆叠成员ID为2，Domain ID为10。此处默认SwitchB的堆叠优先级为100，堆叠连接方式为主控板直连方式，无需配置。

<HUAWEI> system-view
[~HUAWEI] sysname SwitchB
[*HUAWEI] commit
[~SwitchB] stack
[~SwitchB-stack] stack member 2
Warning: The device will use the configuration of member ID 2 after the device resets. Continue? [Y/N]: y
[*SwitchB-stack] stack domain 10
[*SwitchB-stack] quit
[*SwitchB] commit

4.配置堆叠端口。

在SwitchA上创建堆叠端口，并将端口40GE1/0/1～40GE1/0/2、40GE2/0/1～40GE2/0/2加入堆叠端口。在SwitchB上创建堆叠端口，并将端口40GE1/0/1～40GE1/0/2、40GE2/0/1～40GE2/0/2加入堆叠端口。SwitchB的配置与SwitchA类似，配置过程略。

[~SwitchA] port-group group1
[*SwitchA-port-group-group1] group-member 40ge 1/0/1 to 40ge 1/0/2
[*SwitchA-port-group-group1] group-member 40ge 2/0/1 to 40ge 2/0/2
[*SwitchA-port-group-group1] shutdown
[*SwitchA-port-group-group1] quit
[*SwitchA] commit
[~SwitchA] interface stack-port 1
[*SwitchA-Stack-Port1] port member-group interface 40ge 1/0/1 to 1/0/2
Warning: After the configuration is complete,
1.The interface(s) (40GE1/0/1-1/0/2) 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] port member-group interface 40ge 2/0/1 to 2/0/2
Warning: After the configuration is complete,
1.The interface(s) (40GE2/0/1-2/0/2) 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] quit
[*SwitchA] commit

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。
待SwitchA和SwitchB上的物理端口都加入堆叠端口后，再将之前被关闭的端口打开。SwitchB的配置与SwitchA类似，配置过程略。

[~SwitchA] port-group group1
[~SwitchA-port-group-group1] undo shutdown
[*SwitchA-port-group-group1] quit
[*SwitchA] commit
[~SwitchA] quit

端口先关闭然后再打开，这样是为了避免端口因产生CRC错包而导致Error-Down。在端口Up的情况下，如果链路一端被配置为堆叠物理成员端口，另一端为普通业务口，此时端口可能会产生CRC错包。

5.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
LC            : LineCard
MB            : MainBoard
*             : Offline configuration
Isolated Port : The port is in stack mode, but does not belong to any Stack-Port
Attribute Configuration:
---------------------------------------------------------------
 MemberID      Domain         Priority       Mode     Enable
Oper(Conf)   Oper(Conf)      Oper(Conf)   Oper(Conf)   Oper
---------------------------------------------------------------
1(1)         --(10)          100(150)     MB(MB)       Disable
---------------------------------------------------------------
Stack-Port Configuration:
--------------------------------------------------------------------------------
Stack-Port      Member Ports
--------------------------------------------------------------------------------
Stack-Port1     40GE1/0/1           40GE1/0/2           40GE2/0/1
                40GE2/0/2
--------------------------------------------------------------------------------

6.保存配置并使能设备堆叠功能。

保存SwitchA的配置并使能堆叠功能。建议先使能规划为主交换机的SwitchA的堆叠功能。这样SwitchA可以先完成重启，从而优先成为主交换机。

<SwitchA> save
Warning: The current configuration will be written to the device. Continue? [Y/N]: y
<SwitchA> system-view
[~SwitchA] stack
[~SwitchA-stack] stack enable
Warning: Make sure that one or more dual-active detection methods are configured once the conversion is complete and the device enters the stack mode. Switches working in different forward modes cannot set up a CSS.
Current configuration will be converted to the next startup saved-configuration file of stack mode.
System will reboot. Continue? [Y/N]: y

使能堆叠功能后，设备会自动重启。
保存SwitchB的配置并使能堆叠功能。

<SwitchB> save
Warning: The current configuration will be written to the device. Continue? [Y/N]: y
<SwitchB> system-view
[~SwitchB] stack
[~SwitchB-stack] stack enable
Warning: Make sure that one or more dual-active detection methods are configured once the conversion is complete and the device enters the stack mode. Switches working in different forward modes cannot set up a CSS.
Current configuration will be converted to the next startup saved-configuration file of stack mode.
System will reboot. Continue? [Y/N]: y

7.检查堆叠是否组建成功。

通过Console口或管理网口登录堆叠系统，使用命令display stack查看堆叠是否组建成功。当通过管理网口登录时，需要使用主交换机的IP地址。

<SwitchA> display stack
--------------------------------------------------------------------------------
MemberID Role     MAC              Priority   DeviceType         Description
--------------------------------------------------------------------------------
1        Master   006d-8835-2b00   150        CE12804
2        Standby  006d-8835-2c00   100        CE12804
--------------------------------------------------------------------------------

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。

8.配置双主检测。

配置端口10GE1/3/0/5、10GE1/4/0/5、10GE2/3/0/5、10GE2/4/0/5的直连方式的双主检测功能。

<SwitchA> system-view
[~SwitchA] interface 10ge 1/3/0/5
[~SwitchA-10GE1/3/0/5] dual-active detect mode direct
Warning: The interface will block common data packets, except BPDU packets. Continue? [Y/N]: y
[*SwitchA-10GE1/3/0/5] quit
[*SwitchA] interface 10ge 1/4/0/5
[*SwitchA-10GE1/4/0/5] dual-active detect mode direct
Warning: The interface will block common data packets, except BPDU packets. Continue? [Y/N]: y
[*SwitchA-10GE1/4/0/5] quit
[*SwitchA] interface 10ge 2/3/0/5
[*SwitchA-10GE2/3/0/5] dual-active detect mode direct
Warning: The interface will block common data packets, except BPDU packets. Continue? [Y/N]: y
[*SwitchA-10GE2/3/0/5] quit
[*SwitchA] interface 10ge 2/4/0/5
[*SwitchA-10GE2/4/0/5] dual-active detect mode direct
Warning: The interface will block common data packets, except BPDU packets. Continue? [Y/N]: y
[*SwitchA-10GE2/4/0/5] commit
[~SwitchA-10GE2/4/0/5] quit

9.配置堆叠成员端口延迟上报Down状态。

建议配置端口延迟上报Down，防止因端口闪断导致堆叠状态不稳定。

[~SwitchA] port-group group-member 40ge 1/1/0/1 40ge 1/1/0/2 40ge 1/2/0/1 40ge 1/2/0/2 40ge 2/1/0/1 40ge 2/1/0/2 40ge 2/2/0/1 40ge 2/2/0/2
[~SwitchA-port-group] carrier down-hold-time 2000
[*SwitchA-port-group] commit
[~SwitchA-port-group] return

10.保存堆叠系统配置

在堆叠配置完成后，建议立即使用save命令保存堆叠系统配置。

<SwitchA> save
Warning: The current configuration will be written to the device. Continue? [Y/N]: y
