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

------------------------------------------------------------------------------
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]:yb.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。

[Switch1] sysname CORE //为便于记忆，修改集群系统的设备名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
