（2）將核心交換機(jī) 6F-CORE-SW01上與 6F-CORE-SW02相連的接口TenGigabitEthernet5/4和TenGigabitEthernet5/5配置為EtherChannel ：

6F-CORE-SW01(config)#interface range tenGigabitEthernet 5/4 - 5

6F-CORE-SW01(config-if-range)#channel-group 1 mode on

6F-CORE-SW01(config-if-range)#no shutdown

Range command terminated because it failed on TenGigabitEthernet5/4

6F-CORE-SW01(config-if-range)#exit

說明：將核心交換機(jī) 6F-CORE-SW01上與 6F-CORE-SW02相連的接口TenGigabitEthernet5/4和TenGigabitEthernet5/5配置為EtherChannel ，為配置VSL 作準(zhǔn)備。

（3）配置VSS 域名與VSS 主機(jī)號(hào)：

6F-CORE-SW01(config)#switch virtual domain 100

Domain ID 100 config will take effect only

after the exec command 'switch convert mode virtual' is issued

6F-CORE-SW01(config-vs-domain)#switch 1

6F-CORE-SW01(config-vs-domain)#switch 1 priority 200

6F-CORE-SW01(config-vs-domain)#exit

說明：這里沒有配置搶占，因?yàn)檎也坏綋屨歼@個(gè)命令（因?yàn)閍ctive 交換幾只是在控制層面起作用，實(shí)際的數(shù)據(jù)還是各自進(jìn)行轉(zhuǎn)發(fā)所以哪臺(tái)做active 無(wú)所謂）配置VSS 的域名為100，范圍為1-255，兩臺(tái)交換機(jī)必須相同；配置VSS 的主機(jī)號(hào)碼為1，必須一臺(tái)為1，另一臺(tái)為2；并配置VSS 優(yōu)先級(jí)為200，默認(rèn)為100，數(shù)字越大，優(yōu)先級(jí)越高，便能成為主VSS 交換機(jī)。

（4）配置VSL 鏈路：

6F-CORE-SW01(config)#interface port-channel 1

6F-CORE-SW01(config-if)#switch virtual link 1

6F-CORE-SW01(config-if)#no shutdown

6F-CORE-SW01(config-if)#exit

6F-CORE-SW01(config)#exit

說明：將兩臺(tái)交換機(jī)互連的EtherChannel 配置為VSL 。

（5）將交換機(jī)的工作模式改為VSS 模式（確定之后，交換機(jī)將自動(dòng)重啟）： 6F-CORE-SW01#write

Building configuration...

[OK]

6F-CORE-SW01#

6F-CORE-SW01#switch convert mode virtual

（6）查看當(dāng)前交換機(jī)的工作模式：

6F-CORE-SW01#show switch virtual

Switch mode : Virtual Switch

Virtual switch domain number : 100

Local switch number : 1

Local switch operational role: Virtual Switch Active

6F-CORE-SW01#

說明：交換機(jī)當(dāng)前已經(jīng)工作在VSS 模式，并顯示域名為100，本地交換機(jī)號(hào)碼為1，本地交換機(jī)的角色為Active ，即具有控制權(quán)限的主交換機(jī)。

（7）查看當(dāng)前交換機(jī)的VSS 角色：

6F-CORE-SW01#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

Active configured preempt timer(switch 1): 5 minutes

In dual-active recovery mode: No

6F-CORE-SW01#

說明：本地交換機(jī)的角色為Active ，即具有控制權(quán)限的主交換機(jī)。

（8）查看當(dāng)前交換機(jī)的VSL 鏈路狀態(tài)：

6F-CORE-SW01#show switch virtual link

VSL Status : DOWN

VSL Uptime : -

VSL SCP Ping : -

VSL ICC Ping : -

VSL Control Link : -

6F-CORE-SW01#

說明：因?yàn)檫€沒有配置第二臺(tái)交換機(jī)，所以本地交換機(jī)當(dāng)前的VSL 鏈路狀態(tài)為DOWN 。

二:配置核心交換機(jī)SW02

en

conf t

no ip domain lookup

line con 0

exec-timeout 0 0

logging synchronous

exit

username et password et6f

enable secret et6f

hostname 6FF-CORE-SW02

（2）將核心交換機(jī) 6F-CORE-SW02上與 6F-CORE-SW01相連的接口TenGigabitEthernet5/4和TenGigabitEthernet5/5配置為EtherChannel ： 6F-CORE-SW02(config)#int range tenGigabitEthernet 5/4 - 5

6F-CORE-SW02(config-if-range)#channel-group 2 mode on

6F-CORE-SW02(config-if-range)#no shutdown

Range command terminated because it failed on TenGigabitEthernet5/4 6F-CORE-SW02(config-if-range)#exit

說明：將核心交換機(jī) 6F-CORE-SW02上與 6F-CORE-SW01相連的接口

TenGigabitEthernet5/4和TenGigabitEthernet5/5配置為EtherChannel ，為配置VSL 作準(zhǔn)備，請(qǐng)注意雙方的EtherChannel 號(hào)碼不要配置相同。

（3）配置VSS 域名與VSS 主機(jī)號(hào)：

6F-CORE-SW02(config)#switch virtual domain 100

Domain ID 100 config will take effect only

after the exec command 'switch convert mode virtual' is issued

6F-CORE-SW02(config-vs-domain)#switch 2

6F-CORE-SW02(config-vs-domain)#exit

說明：配置VSS 的域名為100，范圍為1-255，兩臺(tái)交換機(jī)必須相同；配置VSS 的主機(jī)號(hào)碼為2，必須一臺(tái)為1，另一臺(tái)為2。

（4）配置VSL 鏈路：

6F-CORE-SW02(config)#int port-channel 2

6F-CORE-SW02(config-if)#switch virtual link 2

6F-CORE-SW02(config-if)#no shutdown

6F-CORE-SW02(config-if)#exi

6F-CORE-SW02(config)#exi

說明：將兩臺(tái)交換機(jī)互連的EtherChannel 配置為VSL 。

（5）將交換機(jī)的工作模式改為VSS 模式（確定之后，交換機(jī)將自動(dòng)重啟）： 6F-CORE-SW02#wr

Building configuration...

[OK]

6F-CORE-SW02#

6F-CORE-SW02#switch convert mode virtual

之后會(huì)出現(xiàn)一個(gè)選項(xiàng):選yes

啟動(dòng)完成后:核心sw02:進(jìn)入standby 狀態(tài)

說明：由于對(duì)端交換機(jī) 6F-CORE-SW01的VSS 優(yōu)先級(jí)高于本交換機(jī)，所以對(duì)方交換機(jī)已經(jīng)工作在了VSS 的Active 狀態(tài)，而本地交換機(jī) 6F-CORE-SW02只能工作在Standby 狀態(tài)；只有工作在Active 模式的交換機(jī)才具有配置和管理雙方交換機(jī)的權(quán)限，而工作在Standby 狀態(tài)的交換機(jī)則永遠(yuǎn)停留在用戶模式（提示符為>），enable 模式是被阻塞而不能進(jìn)入的。

并且需要注意，當(dāng)兩臺(tái)交換機(jī)通過VSS 合并成單臺(tái)交換機(jī)之后，主機(jī)名則沿用Active 交換機(jī)的主機(jī)名。

（1）查看核心交換機(jī) 6F-CORE-SW01的EtherChannel 狀態(tài)：

6F-CORE-SW01#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: 1

Number of aggregators: 1

Group Port-channel Protocol Ports

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

1 Po1(RD) - Te1/5/4(w) Te1/5/5(D)

6F-CORE-SW01#

說明：核心交換機(jī) 6F-CORE-SW01當(dāng)前的EtherChannel 并未工作在正常狀態(tài)，所以下面需要解決此問題。

說明：由于兩臺(tái)核心交換機(jī)之間配置了VSS ，所以兩臺(tái)交換機(jī)的配置信息將合并為一臺(tái)， 6F-CORE-SW01之前的接口GigabitEthernet1/2現(xiàn)在變?yōu)镚igabitEthernet1/1/2，之前的接口GigabitEthernet2/3現(xiàn)在變?yōu)镚igabitEthernet1/2/3，之前的接口TenGigabitEthernet5/4現(xiàn)在變?yōu)門enGigabitEthernet1/5/4，而 6F-CORE-SW02之前的接口GigabitEthernet1/2現(xiàn)在變?yōu)镚igabitEthernet2/1/2，之前的接口GigabitEthernet2/3現(xiàn)在變?yōu)镚igabitEthernet2/2/3，之前的接口TenGigabitEthernet5/4現(xiàn)在變?yōu)門enGigabitEthernet2/5/4；除此之外，最重要的就是之前雙方都配置好的EtherChannel ，現(xiàn)在只剩Active 交換機(jī) 6F-CORE-SW01的TenGigabitEthernet1/5/4和TenGigabitEthernet1/5/5還正常存在，而Standby 交換機(jī) 6F-CORE-SW02的EtherChannel 配置在經(jīng)過VSS 合并之后被清空，所以必須手工添加交換機(jī) 6F-CORE-SW02上應(yīng)有的EtherChannel 配置和VSL 配置，否則雙方的VSL 將不能正常工作，那么VSS 也就不能正常工作。（也有些型號(hào)的設(shè)備不需要做這一步vsl 就up 了）

（3）手工添加交換機(jī) 6F-CORE-SW02上應(yīng)有的EtherChannel 配置和VSL 配置： 6F-CORE-SW01(config)#int range tenGigabitEthernet 2/5/4 - 5

6F-CORE-SW01(config-if-range)#channel-group 2 mode on

6F-CORE-SW01(config-if-range)#no shutdown

Range command terminated because it failed on TenGigabitEthernet2/5/4 6F-CORE-SW01(config-if-range)#exit

00:10:36: ?-5-STAYDOWN: Te2/5/4 will remain down as its port-channel Po2 is admin-down

6F-CORE-SW01(config)#

6F-CORE-SW01(config)#int port-channel 2

6F-CORE-SW01(config-if)#switch virtual link 2

6F-CORE-SW01(config-if)#no shutdown

6F-CORE-SW01(config-if)#exit

6F-CORE-SW01(config)#exit

6F-CORE-SW01#

00:11:03: SYS-5-CONFIG_I: Configured from console by consolewr

6F-CORE-SW01#write

Building configuration...

00:14:16: PFINIT-SW1_SP-5-CONFIG_SYNC: Sync'ing the startup configuration to the standby Router. [OK]

6F-CORE-SW01#

說明：雖然是配置 6F-CORE-SW02的EtherChannel 和VSL ，但還是在VSS 的Active 交換機(jī)上配置的，因?yàn)?6F-CORE-SW02工作在Standby 狀態(tài)，是不能進(jìn)入enable 進(jìn)行配置和管理的。

（4）再次查看交換機(jī) 6F-CORE-SW01的工作模式：

6F-CORE-SW01#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 6F-CORE-SW01#

說明：交換機(jī) 6F-CORE-SW01當(dāng)前工作在VSS 模式，并顯示域名為100，本地交換機(jī)號(hào)碼為1，本地交換機(jī)的角色為Active ，即具有控制權(quán)限的主交換機(jī)，而對(duì)端交換機(jī)號(hào)碼為2，并且對(duì)端交換機(jī)角色為Standby 。

查看交換機(jī)當(dāng)前的SSO 狀態(tài)：

6F-CORE-SW01#

6F-CORE-SW01#show redundancy states

my state = 13 -ACTIVE

peer state = 8 -STANDBY HOT

Mode = Duplex

Unit = Primary

Unit ID = 21

Redundancy Mode (Operational) = sso
