搭建集群环境

a.为两台交换机上电，按照数据规划分别对两台框式交换机进行配置

<HUAWEI> system-view 
[HUAWEI] sysname Switch1
[Switch1] set css id 1 
[Switch1] set css priority 150  //框1的集群优先级配置为150
[Switch1] interface css-port 1
[Switch1-css-port1] port interface xgigabitethernet 4/0/1 to xgigabitethernet 4/0/2 enable
[Switch1-css-port1] quit
[Switch1] interface css-port 2
[Switch1-css-port2] port interface xgigabitethernet 5/0/1 to xgigabitethernet 5/0/2 enable
[Switch1-css-port2] quit
[Switch1] display css status saved  //查看集群配置是否正确  
CSS port media-type: SFP+                                                              
Current Id   Saved Id     CSS Enable   CSS Mode    Priority    Master force      
------------------------------------------------------------------------------  
1            1            Off          LPU         150         Off   

[Switch1] css enable  //集群配置确认正确后，使能集群，重启设备，为保证框ID成为主交换机，先重启Switch1
Warning: The CSS configuration will take effect only after the system is rebooted. The next CSS mode is CSS card. Reboot now? [Y/N]:y

<HUAWEI> system-view 
[HUAWEI] sysname Switch2
[Switch2] set css id 2  //框2的集群优先级使用缺省值，不需要配置。
[Switch2] interface css-port 1
[Switch2-css-port1] port interface xgigabitethernet 4/0/1 to xgigabitethernet 4/0/2 enable
[Switch2-css-port1] quit
[Switch2] interface css-port 2
[Switch2-css-port2] port interface xgigabitethernet 5/0/1 to xgigabitethernet 5/0/2 enable
[Switch2-css-port2] quit
[Switch2] display css status saved //查看集群配置是否正确
CSS port media-type: SFP+                                                              
Current Id   Saved Id     CSS Enable   CSS Mode    Priority    Master Force                
------------------------------------------------------------------------------ 
1            2            Off          LPU         1           Off     
[Switch2] css enable  //集群配置确认正确后，使能集群，重启设备
Warning: The CSS configuration will take effect only after the system is rebooted. The next CSS mode is CSS card. Reboot now? [Y/N]:y

b.交换机重启后，查看集群是否组建成功

#通过交换机框上主控板的集群指示灯查看集群状态。

Switch1主控板上ACT灯绿色常亮，表示该主控板为集群系统主用主控板，Switch1为主交换机。

Switch2主控板上ACT灯绿色闪烁，表示该主控板为集群系统备用主控板，Switch2为备交换机。

#通过任意主控板上的Console口登录集群系统，使用命令行查看集群组建是否成功。

根据集群优先级，优先级大的Switch1会成为集群系统的主框，执行命令display device查看设备状态时，集群系统名为Switch1。

c.集群组建完成，配置多主检测

集群组建完成后，为防止集群故障分裂导致多主影响业务，在两台交换机直接连接一条线缆，用于多主检测。线缆对应的接口分别为XGE1/1/0/10和XGE2/1/10

[CORE] interface xgigabitethernet 1/1/0/10 
[CORE-XGigabitEthernet1/1/0/10] mad detect mode direct 
Warning: This command will block the port, and no other configuration running on this port is recommended. Continue?[Y/N]:y [CORE-XGigabitEthernet1/1/0/10] quit
[CORE] interface xgigabitethernet 2/1/0/10 
[CORE-XGigabitEthernet2/1/0/10] mad detect mode direct 
Warning: This command will block the port, and no other configuration running on this port is recommended. Continue?[Y/N]:y [CORE-XGigabitEthernet2/1/0/10] return
<CORE> display mad verbose   //查看多主检测配置
Current MAD domain: 0               
Current MAD status: Detect             
Mad direct detect interfaces configured:        
 XGigabitEthernet1/1/0/10                
 XGigabitEthernet2/1/0/10               
Mad relay detect interfaces configured:          
Excluded ports(configurable):                 
Excluded ports(can not be configured):

d.在集群上配置Eth-Trunk接口

<CORE> system-view 
[CORE] interface eth-trunk 10  //创建与AGG1相连的Eth-Trunk接口
[CORE-Eth-Trunk10] mode lacp
[CORE-Eth-Trunk10] quit 
[CORE] interface xgigabitethernet 1/1/0/1 
[CORE-XGigabitEthernet1/1/0/1] eth-trunk 10 
[CORE-XGigabitEthernet1/1/0/1] quit 
[CORE] interface xgigabitethernet 2/1/0/2 
[CORE-XGigabitEthernet2/1/0/2] eth-trunk 10 
[CORE-XGigabitEthernet2/1/0/2] quit
[CORE] interface eth-trunk 20  //创建与AGG2相连的Eth-Trunk接口
[CORE-Eth-Trunk20] mode lacp
[CORE-Eth-Trunk20] quit 
[CORE] interface xgigabitethernet 1/1/0/2 
[CORE-XGigabitEthernet1/1/0/2] eth-trunk 20 
[CORE-XGigabitEthernet1/1/0/2] quit 
[CORE] interface xgigabitethernet 2/1/0/1 
[CORE-XGigabitEthernet2/1/0/1] eth-trunk 20 
[CORE-XGigabitEthernet2/1/0/1] quit
