switch-1#
说明：由于 两台核心交换机之间配置了VSS，所以两台交换机的配置信息将合并为一台，65-1之前的接口GigabitEthernet1/2现在变为 GigabitEthernet1/1/2，之前的接口GigabitEthernet2/3现在变为GigabitEthernet1/2/3，之前的 接口TenGigabitEthernet5/4现在变为TenGigabitEthernet1/5/4，而65-2之前的接口 GigabitEthernet1/2现在变为GigabitEthernet2/1/2，之前的接口GigabitEthernet2/3现在变为 GigabitEthernet2/2/3，之前的接口TenGigabitEthernet5/4现在变为TenGigabitEthernet2/5 /4；除此之外，最重要的就是之前双方都配置好的EtherChannel，现在只剩Active交换机65-1的 TenGigabitEthernet1/5/4和TenGigabitEthernet1/5/5还正常存在，而Standby交换机65-2的 EtherChannel配置在经过VSS合并之后被清空，所以必须手工添加交换机65-2上应有的EtherChannel配置和VSL配置，否则双方 的VSL将不能正常工作，那么VSS也就不能正常工作。
（3）手工添加交换机65-2上应有的EtherChannel配置和VSL配置：
switch-1(config)#int range tenGigabitEthernet 2/5/4 - 5
switch-1(config-if-range)#channel-group 20 mode on
switch-1(config-if-range)#no shutdown
% Range command terminated because it failed on TenGigabitEthernet2/5/4
switch-1(config-if-range)#exit
00:10:36: %EC-5-STAYDOWN: Te2/5/4 will remain down as its port-channel Po20 is admin-down
switch-1(config)#
switch-1(config)#int port-channel 20
switch-1(config-if)#switch virtual link 2
switch-1(config-if)#no shutdown
switch-1(config-if)#exit
switch-1(config)#exit
switch-1#
00:11:03: %SYS-5-CONFIG_I: Configured from console by consolewr
switch-1#write
Building configuration...
00:14:16: %PFINIT-SW1_SP-5-CONFIG_SYNC: Sync'ing the startup configuration to the standby Router. [OK]
switch-1#
说明：虽然是配置65-2的EtherChannel和VSL，但还是在VSS的Active交换机上配置的，因为65-2工作在Standby状态，是不能进入enable进行配置和管理的。
（4）再次查看交换机65-1的工作模式：
switch-1#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
Conversion completed : No
Perform exec command 'switch accept mode virtual' to complete the VSS conversion
switch-1#
说明：交换机65-1当前工作在VSS模式，并显示域名为100，本地交换机号码为1，本地交换机的角色为Active，即具有控制权限的主交换机，而对端交换机号码为2，并且对端交换机角色为Standby。
（5）查看当前交换机的VSS角色：
switch-1#show switch virtual role
Switch Switch Status Preempt Priority Role Session ID
Number Oper(Conf) Oper(Conf) Local Remote
------------------------------------------------------------------
LOCAL 1 UP TRUE (Y*) 200(200) ACTIVE 0 0
REMOTE 2 UP TRUE (Y*) 100(100) STANDBY 6887 6831
Active configured preempt timer(switch 1): 5 minutes
In dual-active recovery mode: No
switch-1#
说明：本地交换机65-1的角色为Active，即具有控制权限的主交换机，而对端交换机角色为Standby。
（6）查看当前交换机的VSL链路状态：
switch-1#show switch virtual link
VSL Status : UP
VSL Uptime : 5 minutes
VSL SCP Ping : Pass
VSL ICC Ping : Fail
VSL Control Link : Te1/5/4
switch-1#
说明：当前交换机双方的VSL链路已经工作正常。
（7）再次查看核心交换机65-1的EtherChannel状态：
switch-1#sh etherchannel summary
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use N - not in use, no aggregation
f - failed to allocate aggregator
M - not in use, no aggregation due to minimum links not met
m - not in use, port not aggregated due to minimum links not met
u - unsuitable for bundling
d - default port
w - waiting to be aggregated
Number of channel-groups in use: 2
Number of aggregators: 2

20 Po20(RU) - Te2/5/4(P) Te2/5/5(D)
switch-1#
说明：目前 EtherChannel状态已经工作正常，虽然双方VSL互连的链路为TenGigabitEthernet5/4和 TenGigabitEthernet5/5，但本实验中只在TenGigabitEthernet5/4之间连接了单条光纤，所以 TenGigabitEthernet5/5的状态为D。
（8）再次查看交换机当前的SSO状态：
switch-1#
switch-1#show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 21
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured) = sso
Redundancy State = sso
Maintenance Mode = Disabled
Communications = Up
client count = 72
client_notification_TMR = 30000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 1
keep_alive threshold = 18
RF debug mask = 0x0
switch-1#
switch-1#
说明：本地交换机当前的SSO状态为ACTIVE，而对端为STANDBY HOT，表明工作正常，如果对端不是工作在STANDBY HOT，则必须解决该问题，除STANDBY HOT之外的任何状态都为不正常。
VSS故障测试
1．手工命令故障切换 （1）在Active交换机65-1上输入命令手工执行故障切换（命令输入之后，本地交换机将自动重启）：
switch-1#redundancy force-switchover

switch-1#
switch-1#
说明：原本工作在Standby状态的交换机65-2在Active交换机65-1出现故障时接替了Active的角色，所以现在65-2已经可以进入enable模式进行配置和管理了。
（3）查看交换机65-2当前的工作模式：
switch-1#show switch virtual
Switch mode : Virtual Switch
Virtual switch domain number : 100
Local switch number : 2
Local switch operational role: Virtual Switch Active
Peer switch number : 1
Peer switch operational role : Virtual Switch Standby
switch-1#
说明：结果显示当前交换机的号码为2，即为交换机65-2，并且目前交换机65-2的角色为Active，即具有控制权限的主交换机，而交换机65-1目前角色为Standby。
（4）查看当前交换机的VSS角色：
switch-1#show 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

switch-1#
说明：结果显示当前交换机的号码为2，即为交换机65-2，并且目前交换机65-2的角色为Active，即具有控制权限的主交换机，而交换机65-1目前角色为Standby。
（5）查看当前交换机的VSL链路状态：
switch-1#show switch virtual link
VSL Status : UP
VSL Uptime : 3 minutes
VSL SCP Ping : Pass
VSL ICC Ping : Pass
VSL Control Link : Te2/5/4
switch-1#
说明：当前交换机双方的VSL链路已经工作正常。
（6）查看交换机当前的SSO状态：
switch-1#show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 37
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured) = sso

keep_alive threshold = 18
RF debug mask = 0x0
switch-1#
switch-1#
说明：本地交换机当前的SSO状态为ACTIVE，而对端为STANDBY HOT，表明工作正常。
2．关闭电源故障切换
说明：目前核心交换机65-2为VSS的Active交换机，而65-1工作在Standby状态，所以应该关闭核心交换机65-2的电源来做故障切换测试。
（1）连接目前工作在Standby状态的交换机65-1，并观察关闭Active交换机65-2的电源之后，65-1的状态变化：

配置Multichassis EtherChannel (MEC)
说明：继续以上图为例，配置VSS核心交换机与接入交换机2960之间的Multichassis EtherChannel (MEC)。
1．配置Multichassis EtherChannel (MEC)
（1）在VSS核心交换机上配置Multichassis EtherChannel (MEC)：
switch-1(config)#interface gigabitEthernet 1/1/1 , g2/1/1
switch-1(config-if-range)#switchport
switch-1(config-if-range)#no shutdown
% Range command terminated because it failed on TenGigabitEthernet5/4
switch-1(config-if-range)#channel-group 100 mode desirable
switch-1(config-if-range)#exit
switch-1(config)#interface port-channel 100
switch-1(config-if)#switchport mode access
switch-1(config-if)#switchport access vlan 100
switch-1(config-if)#no shutdown
switch-1(config-if)#exit
说明：在VSS核心交换机上将连接接入交换机2960的两个光接口gigabitEthernet 1/1/1和gigabitEthernet 2/1/1配置为Multichassis EtherChannel (MEC)，并且配置为2层access接口，然后划入VLAN 100中。
（2）在接入交换机2960上配置普通EtherChannel：
2960(config)#interface gigabitEthernet 0/21 - 22
2960(config-if-range)#no shutdown
2960(config-if-range)#channel-group 1 mode desirable
2960(config-if-range)#exit
2960(config)#interface port-channel 1
2960(config-if)#switchport mode access
2960(config-if)#switchport access vlan 100
2960(config-if)#exit
说明：在接入交换机2960上将连接VSS核心交换机两个光接口gigabitEthernet 0/21和gigabitEthernet 0/22配置为普通EtherChannel即可，并且划入VLAN 100中。
（3）查看VSS核心交换机上的EtherChannel状态：
switch-1#show etherchannel summary
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use N - not in use, no aggregation
f - failed to allocate aggregator
M - not in use, no aggregation due to minimum links not met
m - not in use, port not aggregated due to minimum links not met
u - unsuitable for bundling
d - default port
w - waiting to be aggregated
Number of channel-groups in use: 3
Number of aggregators: 3
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
10 Po10(RU) - Te1/5/4(P) Te1/5/5(D)
20 Po20(RU) - Te2/5/4(P) Te2/5/5(D)
100 Po100(SD) PAgP Gi1/1/1(P) Gi2/1/1(P)
switch-1#
说明：VSS核心交换机上显示与接入交换机之间的EtherChannel工作正常。
（4）查看接入交换机2960上的EtherChannel状态：
2960#show etherchannel summary
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator
M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
d - default port
Number of channel-groups in use: 1
Number of aggregators: 1
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
1 Po1(SU) PAgP Gi0/21(P) Gi0/22(P)
2960#
说明：接入交换机2960上与VSS核心交换机之间的EtherChannel工作正常。
2．测试交换机之间的EtherChannel连通性
（1）在VSS核心交换机上创建SVI接口，并配置IP地址：
switch-1(config)#int vlan 100
switch-1(config-if)#ip add 100.1.1.1 255.255.255.0
switch-1(config-if)#no shutdown
说明：在VSS核心交换机上创建与2960之间的SVI接口，以作测试。
（2）在接入交换机2960上创建SVI接口，并配置IP地址：
2960(config)#int vlan 100
2960(config-if)#ip add 100.1.1.2 255.255.255.0
2960(config-if)#no shutdown
说明：在接入交换机2960上创建与VSS核心交换机之间的SVI接口，以作测试。
（3）测试VSS核心交换机与2960之间的连通性：
switch-1#ping 100.1.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 100.1.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
switch-1#
说明：VSS核心交换机与2960之间的通信正常。
（4）测试2960与VSS核心交换机之间的连通性：
2960#ping 100.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 100.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
2960#
说明：2960与VSS核心交换机之间的通信正常。
注：当VSS中Active交换机出现故障之后，Standby交换机在接替Active工作时，接入交换机与核心交换机之间的通信可能出现毫秒级的中断，如果使用ICMP作ping测试，会出现1个丢包，也有时会不丢包，因为中断是毫秒级的。
