VSS Configure
1.定义domain----ID范围1-255
On Switch 1:
podx-vss-sw1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
podx-vss-sw1(config)#switch virtual domain x
Domain ID 1 config will take effect only
after the exec command 'switch convert mode virtual' is issued
podx-vss-sw1(config-vs-domain)#switch 1
podx-vss-sw1(config-vs-domain)#
On Switch 2:
podx-vss-sw2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
podx-vss-sw2(config)#switch virtual domain x
Domain ID 1 config will take effect only
after the exec command 'switch convert mode virtual' is issued
podx-vss-sw2(config-vs-domain)#switch 2
podx-vss-sw2(config-vs-domain)#
2.定义优先级----越大越优先
On Switch 1:
pod1-vss-sw1(config-vs-domain)#switch 1 priority 110
pod1-vss-sw1(config-vs-domain)#switch 2 priority 100
On Switch 2:
pod1-vss-sw2(config-vs-domain)#switch 1 priority 110
pod1-vss-sw2(config-vs-domain)#switch 2 priority 100
3.配置Virtual Switch Link (VSL)----最多8个10GE口捆绑(必须用10GE口）
控制面板通过VSL实现两个机箱的CPU到CPU的通讯，数据面板通过VSL扩展本机箱的交换矩阵到远端。
On Switch 1:
pod1-vss-sw1(config)#interface port-channel 1
pod1-vss-sw1(config)#no shut
pod1-vss-sw1(config-if)#switch virtual link 1
pod1-vss-sw1(config-if)#exit
pod1-vss-sw1(config)#interface range tenGigabitEthernet 1/4 - 5
pod1-vss-sw1(config-if-range)#no shut
pod1-vss-sw1(config-if-range)#channel-group 1 mode on
pod1-vss-sw1(config-if-range)#^Z
On Switch 2:
pod1-vss-sw2(config)#int port-channel 2
pod1-vss-sw2(config-if)#no shut
pod1-vss-sw2(config-if)#switch virtual link 2
pod1-vss-sw2(config-if)#exit
pod1-vss-sw2(config)#interface range tenGigabitEthernet 1/4 - 5
pod1-vss-sw2(config-if-range)#no shut
pod1-vss-sw2(config-if-range)#channel-group 2 mode on
pod1-vss-sw2(config-if-range)#^Z
4.执行转换-----转换完记得重启(重启不分先后可独立完成）,重启后端口命名变成三级编码，switch2的console不在可用，所有控制都通过switch1来做
On Switch 1:
pod1-vss-sw1#switch convert mode virtual
This command will convert all interface names
to naming convention "interface-type switch-number/slot/port",
save the running config to startup-config and
reload the switch.
Do you want to proceed? [yes/no]: yes
Converting interface names
Building configuration...
On Switch 2:
pod1-vss-sw2#switch convert mode virtual
This command will convert all interface names
to naming convention "interface-type switch-number/slot/port",
save the running config to startup-config and
reload the switch.
Do you want to proceed? [yes/no]: yes
Converting interface names
Building configuration...
5.在SWITCH1 上对switch2的VSL作最终配置（注意这里不能用range）
pod1-vss-sw1(config)#interface port-channel 2
pod1-vss-sw1(config-if)#no shut
pod1-vss-sw1(config-if)#switch virtual link 2
pod1-vss-sw1(config-if)#exit
pod1-vss-sw1(config)#interface tenGigabitEthernet 2/1/4
pod1-vss-sw1(config-if)#channel-group 2 mode on
pod1-vss-sw1(config-if)#exit
pod1-vss-sw1(config)#interface tenGigabitEthernet 2/1/5
pod1-vss-sw1(config-if)#channel-group 2 mode on
6.到此为止两台65已经一台了，可以改名并保存配置
podx-vss-sw1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
podx-vss-sw1(config)#hostname podx-vss
podx-vss(config)#^Z
podx-vss#
00:13:40: %SYS-5-CONFIG_I: Configured from console by console
podx-vss#
podx-vss#wr
Building configuration...
00:16:23: %PFINIT-SP-5-CONFIG_SYNC: Sync'ing the startup configuration to the standby Router.
[OK]
podx-vss#
至此VSS配置全部完成！！
7.查看VSS 状态
1） pod1-vss#sh module switch 1
Switch Number: 1 Role: Virtual Switch Active
---------------------- -----------------------------
Mod Ports Card Type Model Serial No.
--- ----- -------------------------------------- ------------------ -----------
1 5 Supervisor Engine 720 10GE (Active) WS-S720-10G SAD104707A7

3 48 CEF720 48 port 10/100/1000mb Ethernet WS-X6748-GE-TX SAD074102UP
2）pod1-vss#sh module switch 2
Switch Number: 2 Role: Virtual Switch Standby
---------------------- -----------------------------

3 48 CEF720 48 port 10/100/1000mb Ethernet WS-X6748-GE-TX SAD074206UM
3）pod1-vss#sh run switch 1

4）pod1-vss#sh run switch 2

5）pod1-vss#sh switch virtual
Switch mode : Virtual Switch
Local switch number : 1
Local switch operational role: Virtual Switch Active
Peer switch number : 2
Peer switch operational role : Virtual Switch Standby
6）pod1-vss#sh switch virtual link
VSL Status : UP
VSL Uptime : 18:36:43 UTC Apr 6 2007
VSL SCP Ping : Pass
VSL ICC Ping : Pass
VSL Control Link : Te1/1/4
7）pod1-vss#sh switch virtual role
Switch Switch Status Preempt Priority Role Session ID
Number Oper(Conf) Oper(Conf) Local Remote
------------------------------------------------------------------
LOCAL 1 UP FALSE(N) 110(110) ACTIVE 0 0
REMOTE 2 UP FALSE(N) 100(100) STANDBY 4217 6561
In dual-active recovery mode: No
8.功能性配置
VSS配置完并工作正常后就可以进行功能性配置了，功能性配置和传统交换机是一模一样的，只是在做配置时可以将两台交换机可以看作一台（比如可以跨机箱做port-Channel）
9.重启active交换机
1）podx-vss#redundancy reload shelf 1
Reload this shelf [confirm]
Preparing to reload this shelf
active的交换机会触发一个NSF/SSO切换，standby的交换机会成为active,这个切换过程是比较短的。
重启期间vss状态----switch 2变成了active，可以通过show 查看
2）podx-vss#sh switch virtual
Switch mode : Virtual Switch
Local switch number : 2
Local switch operational role: Virtual Switch Active
3）重启完后再看VSS状态----switch2 是active switch 1是standby
podx-vss#sh switch virtual
Switch mode : Virtual Switch
Local switch number : 2
Local switch operational role: Virtual Switch Active
Peer switch number : 1
Peer switch operational role : Virtual Switch Standby
podx-vss#sh switch virtual role
Switch Switch Status Preempt Priority Role Session ID
Number Oper(Conf) Oper(Conf) Local Remote
------------------------------------------------------------------
LOCAL 2 UP FALSE(N) 100(100) ACTIVE 0 0
REMOTE 1 UP FALSE(N) 110(110) STANDBY 4252 7907
10. VSLP Link Management Protocol (LMP) information，主要用来管理VLS组中的成员工作情况。
pod1-vss#sh vslp lmp summary
Instance #2:

11. VSLP Ping
可以在Active 交换机中执行VSLP PING来检查VSL组中的每对接口工作是否正常
pod1-vss#ping vslp output interface tenGigabitEthernet 2/1/4
Type escape sequence to abort.
Sending 5, 100-byte VSLP ping to peer-sup via output port 2/1/4, timeout is 2 seconds
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/14/16 ms
pod1-vss#ping vslp output interface tenGigabitEthernet 2/1/5
Type escape sequence to abort.
Sending 5, 100-byte VSLP ping to peer-sup via output port 2/1/5, timeout is 2 seconds
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/12/16 ms
