VSS配置

Cisco的VSS与H3C的IRF相似

步聚

6509-1配置

第一步、初始化Catalyst 6509交换机

VSS-sw1#conf t

6509-2配置

VSS-sw2#conf t

第二步、

配置VSS Domain ID；

VSS-sw1(config)#switch virtual  domain 100

Domain ID 100 config will take

effect only

after the exec command ‘switch

convert mode virtual’ is issued

VSS-sw2(config)#switch virtual  domain 100

第三步、

设置交换机Switch ID；

VSS-sw1(config-vs-domain)#switch 1

VSS-sw2(config-vs-domain)#switch 2

第四步、

检验交换机Switch ID；

VSS-sw1#switch read switch_num

Read switch_num from rommon is 1

VSS-sw2#switch read switch_num

Read switch_num from rommon is 2

第五步、

配置VSL；

VSS-sw1(config)#interface portchannel 1

VSS-sw1(config-if)#switch virtual link 1

VSS-sw1(config-if)#no shut

VSS-sw2(config)#interface portchannel 2

VSS-sw2(config-if)#switch virtual link 2

VSS-sw2(config-if)#no shut

物理接口划入端口组

VSS-sw1(config)#interface range

tenGigabitEthernet 5/4 - 5

VSS-sw1(config-if-range)#channelgroup 1 mode on

VSS-sw1(config-if-range)#no shut

Switch-1# platform hardware vsl pfc mode pfc3c

VSS-sw2(config)#interface range

VSS-sw2(config-if-range)#channelgroup 2 mode on

VSS-sw2(config-if-range)#no shut

Switch-2# platform hardware vsl pfc mode pfc3c

第六步、

VSS模式转换

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 startupconfig

and reload the switch.

Do you want to proceed? [yes/no]: yes

Converting interface names

Building configuration...

[OK]

Saving converted configurations

to bootflash …

VSS-sw2#switch convert mode  virtual

to bootflash…

第七步、

重启交换机

System detected Virtual Switch

configuration...

Interface TenGigabitEthernet1/5/4 is member of PortChannel 1

Interface TenGigabitEthernet1/5/5 is member of PortChannel 1

<snip>

00:00:26: %VSL_BRINGUP-6-

MODULE_UP: VSL module in slot 5

switch 1 brought up

Initializing as Virtual Switch Active

00:08:01: SW1_SP: Card inserted in

Switch_number = 2 ,

physical slot 3,

interfaces are now online

VSS >

VSS>en

VSS#

Interface TenGigabitEthernet2/5/4 is member of PortChannel 2

Interface TenGigabitEthernet2/5/5 is member of PortChannel 2

switch 2 brought up

Initializing as Virtual Switch standby

00:01:43: %CRYPTO-6-ISAKMP_ON_OFF:

ISAKMP is OFF

VSS-sdby>

Standby console disabled

第八步、

检验VSS配置

VSS#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

第九步、

主备配置同步

VSS#switch accept mode virtual

This command will bring in all VSL configurations from the standby

switch and populate it into the running configuration.

In addition the startup configurations will be updated with the new

merged configurations.

Do you want proceed? [yes/no]: yes

Merging the standby VSL configuration. . .

第十步、

配置VSL Failure

（有两种方式：）

1、PAGP

2、BFD 

PAGP，好像说下面的接入要在4500以上。反正做试验没有成功。

vss(config)# interface port-channel 20

vss(config-if)# shutdown

vss(config-if)# exit

vss(config)# switch virtual domain 100

vss(config-vs-domain)# dual-active detection pagp

vss(config-vs-domain)# dual-active detection pagp trust channel-group 20

vss(config-vs-domain)# exit

vss(config-if)# no shutdown

vss#conf t

Enter configuration commands, one per line. End with CNTL/Z.

vss(config)#switch virtual domain 100

vss(config-vs-domain)#dual-active detection pagp

vss(config-vs-domain)#dual-active trust channel-group 20

vss(config-vs-domain)#

BFD配置，

试验是成功的。

vss (config)# interface gigabitethernet 1/5/3

vss (config-if)# no switchport

vss(config-if)# ip address 200.230.230.231 255.255.255.0

vss (config-if)# bfd interval 100 min_rx 100 multiplier 50

vss (config-if)# no shutdown

vss(config-if)# interface gigabitethernet 2/5/3

vss(config-if)# no switchport

vss(config-if)# ip address 201.230.230.231 255.255.255.0

vss (config)# switch virtual domain 100

vss (config-vs-domain)# dual-active detection bfd

vss (config-vs-domain)# dual-active pair interface g 1/9/48 interface g 2/1/48 bfd

adding a static route 200.230.230.0 255.255.255.0 Gi2/1/48 for this dual-active pair adding a static route 201.230.230.0 255.255.255.0 Gi1/9/48 for this dual-active pair

vss(config)# exit

vss# show switch virtual dual-active bfd

Bfd dual-active detection enabled: Yes Bfd dual-active interface pairs configured: interface1 Gi1/9/48 interface2 Gi2/1/48

设置两台交换机的priority

vss(config-vs-domain)#switch 1 priority 110

*Jul 7 08:59:11.913: %VSLP-SW1_SPSTBY-5-RRP_RT_CFG_CHANGE: Configured

priority value

is different from operational value.

Change will take effect after config is saved and switch is reloaded.

vss(config-vs-domain)#switch 2 priority 100

vss(config-vs-domain)#^Z

vss#

第十一步、

保存配置

vss(config)#wr
