hostname 6F-CORE-SW

(2)将核心交换机 6F-CORE-SW01上与 6F-CORE-SW02相连的接口TenGigabitEthernet5/4和TenGigabitEthernet5/5配置为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

说明:将核心交换机 6F-CORE-SW01上与 6F-CORE-SW02相连的接口TenGigabitEthernet5/4和TenGigabitEthernet5/5配置为EtherChannel ,为配置VSL 作准备。

(3)配置VSS 域名与VSS 主机号:

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

说明:这里没有配置抢占,因为找不到抢占这个命令(因为active 交换几只是在控制层面起作用,实际的数据还是各自进行转发所以哪台做active 无所谓)配置VSS 的域名为100,范围为1-255,两台交换机必须相同;配置VSS 的主机号码为1,必须一台为1,另一台为2;并配置VSS 优先级为200,默认为100,数字越大,优先级越高,便能成为主VSS 交换机。

,

(4)配置VSL 链路:

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

说明:将两台交换机互连的EtherChannel 配置为VSL 。

(5)将交换机的工作模式改为VSS 模式(确定之后,交换机将自动重启): 6F-CORE-SW01#write

Building configuration...

[OK]

6F-CORE-SW01#

6F-CORE-SW01#switch convert mode virtual

(6)查看当前交换机的工作模式:

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#

说明:交换机当前已经工作在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。

,

(7)查看当前交换机的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#

说明:本地交换机的角色为Active ,即具有控制权限的主交换机。

(8)查看当前交换机的VSL 链路状态:

6F-CORE-SW01#show switch virtual link

VSL Status : DOWN

VSL Uptime : -

VSL SCP Ping : -

VSL ICC Ping : -

VSL Control Link : -

,

6F-CORE-SW01#

说明:因为还没有配置第二台交换机,所以本地交换机当前的VSL 链路状态为DOWN 。

二:配置核心交换机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)将核心交换机 6F-CORE-SW02上与 6F-CORE-SW01相连的接口TenGigabitEthernet5/4和TenGigabitEthernet5/5配置为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

说明:将核心交换机 6F-CORE-SW02上与 6F-CORE-SW01相连的接口

,

TenGigabitEthernet5/4和TenGigabitEthernet5/5配置为EtherChannel ,为配置VSL 作准备,请注意双方的EtherChannel 号码不要配置相同。

(3)配置VSS 域名与VSS 主机号:

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

说明:配置VSS 的域名为100,范围为1-255,两台交换机必须相同;配置VSS 的主机号码为2,必须一台为1,另一台为2。

(4)配置VSL 链路:

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

说明:将两台交换机互连的EtherChannel 配置为VSL 。

(5)将交换机的工作模式改为VSS 模式(确定之后,交换机将自动重启): 6F-CORE-SW02#wr

,

Building configuration...

[OK]

6F-CORE-SW02#

6F-CORE-SW02#switch convert mode virtual

之后会出现一个选项:选yes

启动完成后:核心sw02:进入standby 状态

说明:由于对端交换机 6F-CORE-SW01的VSS 优先级高于本交换机,所以对方交换机已经工作在了VSS 的Active 状态,而本地交换机 6F-CORE-SW02只能工作在Standby 状态;只有工作在Active 模式的交换机才具有配置和管理双方交换机的权限,而工作在Standby 状态的交换机则永远停留在用户模式(提示符为>),enable 模式是被阻塞而不能进入的。

并且需要注意,当两台交换机通过VSS 合并成单台交换机之后,主机名则沿用Active 交换机的主机名。

(1)查看核心交换机 6F-CORE-SW01的EtherChannel 状态:

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#

说明:核心交换机 6F-CORE-SW01当前的EtherChannel 并未工作在正常状态,所以下面需要解决此问题。

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, 6F-CORE-SW01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 6F-CORE-SW02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 6F-CORE-SW01的TenGigabitEthernet1/5/4和TenGigabitEthernet1/5/5还正常存在,而Standby 交换机 6F-CORE-SW02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 6F-CORE-SW02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。(也有些型号的设备不需要做这一步vsl 就up 了)

(3)手工添加交换机 6F-CORE-SW02上应有的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#

说明:虽然是配置 6F-CORE-SW02的EtherChannel 和VSL ,但还是在VSS 的Active 交换机上配置的,因为 6F-CORE-SW02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 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#

说明:交换机 6F-CORE-SW01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 。

查看交换机当前的SSO 状态:

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
