思科VSS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:
Purpose
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:
Purpose
Step 1
Switch-2(config)# switch virtual domain 100
Step 2
Switch-2(config-vs-domain)# switch 2
Step 3
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:
Purpose
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
Exits interface configuration.
SWITCH2:
Purpose
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）(一定确认port-channel先加入switch v irtual link)
SWITCH1:
Switch-1(config)# interface range tengigabitethernet 3/1-2
Switch-1(config-if)# channel-group 10 mode on
witch-1(config-if)# no shutdown
SWITCH2:
Step 1
Switch-2(config)# interface range tengigabitethernet 5/2-3
Switch-2(config-if)# channel-group 20 mode on
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
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
license升级：
思科VSS 45 License升级配置步骤：
1、关闭standby所有非VSL端口
int range gigabitethernet 2/2/1 - 12
sh
int range gigabitethernet 2/3/1 - 12
sh
int range gigabitethernet 2/4/1 - 12
sh
int range gigabitethernet 2/5/1 - 12
sh
int range gigabitethernet 2/6/1 - 12
sh
2、在active上安装license：
license install bootflash:SPE16220060_201309210212042440.lic
3、在active上关闭VSL端口
int ra Tengigabitethernet 1/1/2 - 4
sh
4、在standby上安装license：
license install bootflash:SPE16300069_201309210212562900.lic
5、确认standby的VSL端口没被shutdown，重启standby设备
reload
6、当standby重启时，开启active的VSL端口：
int ra Tengigabitethernet 1/1/2 - 4
no sh
7、当standby处于SSO-HOT模式时，开启所有关闭的端口：
int range gigabitethernet 2/2/1 - 12
no sh
int range gigabitethernet 2/3/1 - 12
no sh
int range gigabitethernet 2/4/1 - 12
no sh
int range gigabitethernet 2/5/1 - 12
no sh
int range gigabitethernet 2/6/1 - 12
no sh
8、在切换两台active/standby，确认license生效：
redundancy force-switchover
sh license inmage levels
9、启用ipbase:
license boot level ipbase
