配置 Cisco VSS 的方法和命令行、脚本
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:
- 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
- Switch-1# show running-config
- Switch-1# show redundancy states //Displays the operating redundancy mode.
- Switch2:
- Switch-2(config)# redundancy
- Switch-2(config-red)# mode sso
- Switch-2(config-red)# exit
- Switch-2# show running-config
- Switch-2# show redundancy states
2.配置虚拟交换机的域(Virtual Switch Domain and Switch Numbers)
- Switch1:
- Step 1
- Switch-1(config)# switch virtual domain 100
- Step 2
- Switch-1(config-vs-domain)# switch 1
- Step 3
- Switch-1(config-vs-domain)# exit
- Switch2:
- Switch-2(config)# switch virtual domain 100
- Switch-2(config-vs-domain)# switch 2
- Switch-2(config-vs-domain)# exit
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:
- Step 1
- Switch-1(config)# interface port-channel 10
- Step 2
- Switch-1(config-if)# switch virtual link 1
- Step 3
- Switch-1(config-if)# no shutdown //Activates the port channel.
- Step 4
- Switch-1(config-if)# exit
- Switch2:
- Switch-2(config)# interface port-channel 20
- Switch-2(config-if)# switch virtual link 2
- Switch-2(config-if)# no shutdown
- Switch-2(config-if)# exit
2)把引擎上的万兆端口加入channel(假设引擎在slot3,一定先确认port-channel已加入switch virtual link)
- Switch1:
- Switch-1(config)# interface range tengigabitethernet 3/1-2
- Switch-1(config-if)# channel-group 10 mode on
- Switch-1(config-if)# no shutdown
- Switch2:
- Step 1
- Switch-2(config)# interface range tengigabitethernet 3/1-2
- Switch-2(config-if)# channel-group 20 mode on
- Switch-2(config-if)# no shutdown
4.转换机箱变成虚拟交换机模式
1)先查看机箱的PFC模式,保证2个机箱相同
- 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
- 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.
2)切换机箱模式
- Switch1:
- 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:
- Switch-2# switch convert mode virtual
5.查看VSS信息
- 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 http://www.xiaoxiongboke.com
- 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
