思科VSS配置命令
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 virtualdomain 100Domain ID 100 config will takeeffect onlyafter the exec command ‘switchconvert mode virtual’ is issued
6509-2配置
VSS-sw2(config)#switch virtualdomain 100
第三步、设置交换机Switch ID；
VSS-sw1(config-vs-domain)#switch 1
6509-2配置
VSS-sw2(config-vs-domain)#switch 2
第四步、检验交换机Switch ID；
VSS-sw1#switch read switch_numRead switch_num from rommon is 1
6509-2配置
VSS-sw2#switch read switch_numRead switch_num from rommon is 2
第五步、配置VSL；
VSS-sw1#conf tVSS-sw1(config)#interface portchannel 1VSS-sw1(config-if)#switch virtual link 1VSS-sw1(config-if)#no shut
6509-2配置
VSS-sw2#conf tVSS-sw2(config)#interface portchannel 2VSS-sw2(config-if)#switch virtual link 2VSS-sw2(config-if)#no shut
物理接口划入端口组
VSS-sw1(config)#interface rangetenGigabitEthernet 5/4 - 5VSS-sw1(config-if-range)#channelgroup 1 mode onVSS-sw1(config-if-range)#no shut
Switch-1# platform hardware vsl pfc mode pfc3c
6509-2配置
VSS-sw2(config)#interface rangetenGigabitEthernet 5/4 - 5VSS-sw2(config-if-range)#channelgroup 2 mode onVSS-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 modevirtualThis command will convert allinterface names to namingconvention “interface-typeswitch-number/slot/port”, savethe running config to startupconfigand reload the switch.Do you want to proceed? : yesConverting interface namesBuilding configuration...Saving converted configurationsto bootflash …
6509-2配置
VSS-sw2#switch convert modevirtualThis command will convert allinterface names to namingconvention “interface-typeswitch-number/slot/port”, savethe running config to startupconfigand reload the switch.Do you want to proceed? : yesConverting interface namesBuilding configuration...Saving converted configurationsto bootflash…
第七步、重启交换机
System detected Virtual Switchconfiguration...Interface TenGigabitEthernet1/5/4 is member of PortChannel 1Interface TenGigabitEthernet1/5/5 is member of PortChannel 1<snip>00:00:26: %VSL_BRINGUP-6-MODULE_UP: VSL module in slot 5switch 1 brought upInitializing as Virtual Switch Active

6509-2配置

第八步、检验VSS配置
VSS#show switch virtualSwitch mode : Virtual SwitchVirtual switch domain number : 100Local switch number : 1Local switch operational role: Virtual Switch ActivePeer switch number : 2Peer switch operational role : Virtual Switch Standby
第九步、主备配置同步
VSS#switch accept mode virtualThis command will bring in all VSL configurations from the standbyswitch and populate it into the running configuration.White PaperAll contents are Copyright1992–2008 Cisco Systems, Inc.

Page 27 of 80In addition the startup configurations will be updated with the newmerged configurations.Do you want proceed? : yesMerging the standby VSL configuration. . .Building configuration...
第十步、配置VSL Failure（有两种方式：）1、PAGP2、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 20vss(config-if)# shutdownvss(config-if)# exitvss(config)# switch virtual domain 100vss(config-vs-domain)# dual-active detection pagpvss(config-vs-domain)# dual-active detection pagp trust channel-group 20vss(config-vs-domain)# exitvss(config)# interface port-channel 20vss(config-if)# no shutdownvss(config-if)# exitvss#conf tEnter configuration commands, one per line. End with CNTL/Z.vss(config)#switch virtual domain 100vss(config-vs-domain)#dual-active detection pagpvss(config-vs-domain)#dual-active trust channel-group 20vss(config-vs-domain)#
BFD配置，试验是成功的。
vss (config)# interface gigabitethernet 1/5/3vss (config-if)# no switchportvss(config-if)# ip address 200.230.230.231 255.255.255.0vss (config-if)# bfd interval 100 min_rx 100 multiplier 50vss (config-if)# no shutdownvss(config-if)# interface gigabitethernet 2/5/3vss(config-if)# no switchportvss(config-if)# ip address 201.230.230.231 255.255.255.0vss (config-if)# bfd interval 100 min_rx 100 multiplier 50vss(config-if)# no shutdownvss(config-if)# exitvss (config)# switch virtual domain 100vss (config-vs-domain)# dual-active detection bfdvss (config-vs-domain)# dual-active pair interface g 1/9/48 interface g 2/1/48 bfdadding 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 pairvss(config-vs-domain)# exitvss(config)# exitvss# show switch virtual dual-active bfdBfd 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priorityvss#conf tEnter configuration commands, one per line. End with CNTL/Z.vss(config)#switch virtual domain 100vss(config-vs-domain)#switch 1 priority 110*Jul 7 08:59:11.913: %VSLP-SW1_SPSTBY-5-RRP_RT_CFG_CHANGE: Configuredpriority valueis different from operational value.Change will take effect after config is saved and switch is reloaded.vss(config-vs-domain)#switch 2 priority 100vss(config-vs-domain)#^Zvss#
第十一步、保存配置
vss#conf tEnter configuration commands, one per line. End with CNTL/Z.vss(config)#wr
