組網需求
在一個新建的數據中心網絡中，要求核心層具有較高的可靠性，並且希望網絡結構簡單，易於配置和管理。
如圖4-1所示，根據用戶需求，核心層SwitchA和SwitchB兩台交換機采取堆疊組網。
配置思路
采用如下的思路配置：
1.提前規划好堆疊方案。
2.按照前期的規划，連接好SwitchA和SwitchB之間的堆疊線纜。
3.在SwitchA和SwitchB上進行堆疊軟件配置，包括堆疊成員ID、堆疊優先級、堆疊域編號、堆疊連接方式、堆疊端口等。
4.保存SwitchA和SwitchB的配置，並使能堆疊功能。
5.檢查堆疊組建是否成功。
6.配置雙主檢測。
操作步驟
1.提前規划堆疊方案。
規划的主要內容如表4-1所示。
表4-1 堆疊規划內容
| 內容 | switchA | switchB |
|---|---|---|
| 堆疊成員角色 | 主交換機 | 備交換機 |
| 堆疊成員ID | 1 | 2 |
| 堆疊優先級 | 150 | 100 |
| 堆疊域編號 | 10 | 10 |
| 堆疊連接方式 | 主控板直連方式 | 主控板直連方式 |
| 堆疊連接端口 | 40GE1/0/1～40GE1/0/2 40GE2/0/1～40GE2/0/2 | 40GE1/0/1～40GE1/0/2 40GE2/0/1～40GE2/0/2 |
| 雙主檢測端口 | 10GE3/0/5 10GE4/0/5 | 10GE3/0/5 10GE4/0/5 |
2.連接堆疊線纜。
如圖4-2所示，按照前期規划連接SwitchA和SwitchB之間的堆疊線纜。連接的端口包括主控板上的SIP口、業務板上的堆疊物理成員端口和雙主檢測端口。
圖4-2 堆疊連接示意圖
3.配置堆疊屬性。
配置SwitchA的優先級為150，Domain ID為10。此處默認SwitchA的堆疊成員ID為1，堆疊連接方式為主控板直連方式，無需配置。
<HUAWEI> system-view
[~HUAWEI] sysname SwitchA
[*HUAWEI] commit
[~SwitchA] stack
[~SwitchA-stack] stack member 1
[~SwitchA-stack] stack priority 150
[*SwitchA-stack] stack domain 10
[*SwitchA-stack] stack link-type mainboard-direct
[*SwitchA-stack] quit
[*SwitchA] commit
配置SwitchB的堆疊成員ID為2，Domain ID為10。此處默認SwitchB的堆疊優先級為100，堆疊連接方式為主控板直連方式，無需配置。
<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] stack link-type mainboard-direct
[*SwitchB-stack] quit
[*SwitchB] commit
4.配置堆疊端口。
在SwitchA上創建堆疊端口，並將端口40GE1/0/1～40GE1/0/2、40GE2/0/1～40GE2/0/2加入堆疊端口。在SwitchB上創建堆疊端口，並將端口40GE1/0/1～40GE1/0/2、40GE2/0/1～40GE2/0/2加入堆疊端口。SwitchB的配置與SwitchA類似，配置過程略。
[~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
被配置為堆疊物理成員端口后，端口下會自動配置port crc-statistics trigger error-down。
待SwitchA和SwitchB上的物理端口都加入堆疊端口后，再將之前被關閉的端口打開。SwitchB的配置與SwitchA類似，配置過程略。
[~SwitchA] port-group group1
[~SwitchA-port-group-group1] undo shutdown
[*SwitchA-port-group-group1] quit
[*SwitchA] commit
[~SwitchA] quit
端口先關閉然后再打開，這樣是為了避免端口因產生CRC錯包而導致Error-Down。在端口Up的情況下，如果鏈路一端被配置為堆疊物理成員端口，另一端為普通業務口，此時端口可能會產生CRC錯包。
5.檢查堆疊配置信息。
上述配置完成后，執行命令display stack configuration查看配置是否與規划的一致，如果不一致，需要修改配置。以查看SwitchA為例。
<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.保存配置並使能設備堆疊功能。
保存SwitchA的配置並使能堆疊功能。建議先使能規划為主交換機的SwitchA的堆疊功能。這樣SwitchA可以先完成重啟，從而優先成為主交換機。
<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
使能堆疊功能后，設備會自動重啟。
保存SwitchB的配置並使能堆疊功能。
<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.檢查堆疊是否組建成功。
通過Console口或管理網口登錄堆疊系統，使用命令display stack查看堆疊是否組建成功。當通過管理網口登錄時，需要使用主交換機的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，顯示兩台交換機的信息，表示堆疊建立成功，且主交換機為成員ID為1的設備，即SwitchA。
8.配置雙主檢測。
配置端口10GE1/3/0/5、10GE1/4/0/5、10GE2/3/0/5、10GE2/4/0/5的直連方式的雙主檢測功能。
<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.配置堆疊成員端口延遲上報Down狀態。
建議配置端口延遲上報Down，防止因端口閃斷導致堆疊狀態不穩定。
[~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.保存堆疊系統配置
在堆疊配置完成后，建議立即使用save命令保存堆疊系統配置。
<SwitchA> save
Warning: The current configuration will be written to the device. Continue? [Y/N]: y
