思科VSS65配置步骤

一、将2台VSS65从单机箱模式切换到虚拟机箱模式

基本步骤：

1.分别在交换机1、2上配置SSO高可用性协议：

2.配置虚拟交换机的域（Virtual Switch Domain and Switch Numbers）

3.配置两台交换机之间的VSL 端口。(利用引擎上的2个万兆光口进行连接)

4.转换机箱变成虚拟交换机模式

 

详细配置：

1.分别在交换机1、2上配置SSO高可用性协议：

SWITCH1:

	Command	Purpose
Step 1	Switch-1(config)# redundancy	Enters redundancy configuration mode.
Step 2	Switch-1(config-red)# mode sso	Configures SSO. When this command is entered, the redundant supervisor engine is reloaded and begins to work in SSO mode.
Step 3	Switch-1(config-red)# exit	Exits redundancy configuration mode.
Step 4	Switch-1# show running-config	Verifies that SSO are configured and enabled.
Step 5	Switch-1# show redundancy states	Displays the operating redundancy mode.

SWITCH2:

	Command	Purpose
Step 1	Switch-2(config)# redundancy	Enters redundancy configuration mode.
Step 2	Switch-2(config-red)# mode sso	Configures SSO. When this command is entered, the redundant supervisor engine is reloaded and begins to work in SSO mode.
Step 3	Switch-2(config-red)# exit	Exits redundancy configuration mode.
Step 4	Switch-2# show running-config	Verifies that SSO are configured and enabled.
Step 5	Switch-2# show redundancy states	Displays the operating redundancy mode.

 

2.配置虚拟交换机的域（Virtual Switch Domain and Switch Numbers）

 SWITCH1:

 

	Command	Purpose
Step 1	Switch-1(config)# switch virtual domain 100	Configures the virtual switch domain on Chassis A.（id可自定义）
Step 2	Switch-1(config-vs-domain)# switch 1	Configures Chassis A as virtual switch number 1.
Step 3	Switch-1(config-vs-domain)# exit	Exits config-vs-domain.

SWITCH2:

	Command	Purpose
Step 1	Switch-2(config)# switch virtual domain 100	Configures the virtual switch domain on Chassis B. （id可自定义）
Step 2	Switch-2(config-vs-domain)# switch 2	Configures Chassis B as virtual switch number 2.
Step 3	Switch-2(config-vs-domain)# exit	Exits config-vs-domain.

 

 

 

3.配置两台交换机之间的VSL 端口。(利用引擎上的2个万兆光口进行连接)

 

1）配置channel

SWITCH1:

	Command	Purpose
Step 1	Switch-1(config)# interface port-channel 10	Configures port channel 10 on Switch 1. （id可自定义,两端的id不一样）
Step 2	Switch-1(config-if)# switch virtual link 1	Associates Switch 1 as owner of port channel 10.
Step 3	Switch-1(config-if)# no shutdown	Activates the port channel.
Step 4	Switch-1(config-if)# exit	Exits interface configuration.

SWITCH2:

	Command	Purpose
Step 1	Switch-2(config)# interface port-channel 20	Configures port channel 20 on Switch 2. （id可自定义,两端的id不一样）
Step 2	Switch-2(config-if)# switch virtual link 2	Associates Switch 2 as owner of port channel 20.
Step 3	Switch-2(config-if)# no shutdown	Activates the port channel.
Step 4	Switch-2(config-if)# exit	Exits interface configuration mode.

 

2）把引擎上的万兆端口加入channel（假设引擎在slot3）

SWITCH1:

	Command	Purpose
Step 1	Switch-1(config)# interface range tengigabitethernet 3/1-2	Enters configuration mode for interface range tengigabitethernet 3/1-2 on Switch 1.
Step 2	Switch-1(config-if)# channel-group 10 mode on	Adds this interface to channel group 10.
Step 3	witch-1(config-if)# no shutdown	Activates the port.

SWITCH2:

	Command	Purpose
Step 1	Switch-2(config)# interface range tengigabitethernet 5/2-3	Enters configuration mode for interface range tengigabitethernet 5/2-3 on Switch 2.
Step 2	Switch-2(config-if)# channel-group 20 mode on	Adds this interface to channel group 20.
Step 3	Switch-2(config-if)# no shutdown	Activates the port.

 

4.转换机箱变成虚拟交换机模式

先查看机箱的PFC模式，保证2个机箱相同

	Command	Purpose
Step 1	Switch-1# show platform hardware pfc mode	Ensures that the PFC operating mode matches on both chassis, to ensure that the VSS comes up in SSO redundancy mode.
Step 2	Switch-2# show platform hardware pfc mode	Ensures that the PFC operating mode matches on both chassis, to ensure that the VSS comes up in SSO redundancy mode.
Step 3	Switch-1(config)# platform hardware vsl pfc mode pfc3c	(Optional) Sets the PFC operating mode to PFC3C on Chassis A.
Step 4	Switch-2(config)# platform hardware vsl pfc mode pfc3c	(Optional) Sets the PFC operating mode to PFC3C on Chassis B.

然后切换机箱模式

SWITCH1:

Command	Purpose
Switch-1# switch convert mode virtual	Converts Switch 1 to virtual switch mode. After you enter the command, you are prompted to confirm the action. Enter yes. The system creates a converted configuration file, and saves the file to the RP bootflash.

SWITCH2:

Command	Purpose
Switch-2# switch convert mode virtual	Converts Switch 2 to virtual switch mode. After you enter the command, you are prompted to confirm the action. Enter yes. The system creates a converted configuration file, and saves the file to the RP bootflash.

 

5.查看VSS信息

 

Command	Purpose
Router# show switch virtual	Displays the virtual switch domain number, and the switch number and role for each of the chassis.
Router# show switch virtual role	Displays the role, switch number, and priority for each of the chassis in the VSS.
Router# show switch virtual link	Displays the status of the VSL.

 

The following example shows the information output from these commands:

Router# show switch virtual

Switch mode                  : Virtual Switch

Virtual switch domain number : 100

Local switch number          : 1

Local switch operational role: Virtual Switch Active

Peer switch number           : 2

Peer switch operational role : Virtual Switch Standby

Router# show switch virtual role

Switch  Switch Status  Preempt    Priority  Role     Session ID

        Number         Oper(Conf) Oper(Conf)         Local  Remote

------------------------------------------------------------------

LOCAL    1     UP      FALSE(N)   100(100)  ACTIVE   0      0  

REMOTE   2     UP      FALSE(N)   100(100)  STANDBY  8158   1991

 

In dual-active recovery mode: No

 

Router# show switch virtual link

VSL Status: UP

VSL Uptime: 4 hours, 26 minutes

VSL SCP Ping: Pass OK

VSL ICC (Ping): Pass

VSL Control Link: Te 1/5/1
