网络需求

l  实现Device0、Device1形成链形堆叠系统，其中Device0成为主控设备。

网络拓扑

图 1‑2配置设备形成链形堆叠系统

配置步骤

步骤1：
 配置Device0。
 

#在Device0上配置虚拟交换成员设备编号为0，并配置域编号为10，优先级为255。

Device0#configure terminal  

Device0(config)#switch virtual member 0

Do you want to modify member id(Yes|No)?y

% Member ID 0 config will take effect only after the exec command 'switch mode virtual' is issued

Device0(config-vst-member-0)#domain 10

% Domain ID 10 config will take effect only after the exec command 'switch mode virtual' is issued

Device0(config-vst-member-0)#priority 255

Device0(config-vst-member-0)#exit

#在Device0上创建虚拟交换链路接口1，并将端口tengigabitethernet1/1和tengigabitethernet1/2加入虚拟交换链路接口1。

Device0(config)#vsl-channel 1

Device0(config-vsl-channel-1)#exit

Device0(config)#interface tengigabitethernet 1/1-1/2

Device0(config-if-range)#vsl-channel 1 mode on

Device0(config-if-range)#exit

#在Device0上保存配置。

Device0#write 

Are you sure to overwrite /flash/startup (Yes|No)?y

Building Configuration...done

Write to startup file ... OK

Write to mode file... OK

步骤2：
 配置Device1。
 

#在Device1上配置虚拟交换成员设备编号为1，并配置域编号为10，优先级为200。

Device1#configure terminal  

Device1(config)#switch virtual member 1

Do you want to modify member id(Yes|No)?y

% Member ID 1 config will take effect only after the exec command 'switch mode virtual' is issued

Device1(config-vst-member-1)#domain 10

% Domain ID 10 config will take effect only after the exec command 'switch mode virtual' is issued

Device1(config-vst-member-1)#priority 200

Device1(config-vst-member-1)#exit

#在Device1上创建虚拟交换链路接口1，并将端口tengigabitethernet1/1和tengigabitethernet1/2加入虚拟交换链路接口1。

Device1(config)#vsl-channel 1

Device1(config-vsl-channel-1)#exit

Device1(config)#interface tengigabitethernet 1/1-1/2

Device1(config-if-range)#vsl-channel 1 mode on

Device1(config-if-range)#exit

#在Device1上保存配置。

Device1#write 

Are you sure to overwrite /flash/startup (Yes|No)?y

Building Configuration...done

Write to startup file ... OK

Write to mode file... OK

步骤3：
 配置Device0、Device1运行模式为堆叠模式。
 

#配置Device0运行模式为堆叠模式。

Device0#switch mode virtual 

This command will convert all interface names to naming convention "interface-type member-number/slot/interface" , 

Please make sure to save current configuration.Do you want to proceed? (yes|no)?y

Converting interface names Building configuration...

Copying the startup configuration to backup file named "startup-backupalone"...

Please wait...system reloading is in progress!

 ok

Reset system!

#配置Device1运行模式为堆叠模式。

Device1#switch mode virtual 

This command will convert all interface names to naming convention "interface-type member-number/slot/interface" ,

步骤4：
 检验结果。
 

#在Device0上查看，已经形成链形堆叠系统，且Device0为主控设备。

Device0#show switch virtual 

Codes: L - local-device,I - isolate-device

Virtual Switch Mode        : VIRTUAL

Virtual Switch DomainId    : 10
