Cisco vss 配置过程第一步：VSS系统配置备份原设备配置Switch# copy running-config startup-config /保存当前配置到start-config文件里Switch# copy startup-config disk0:old-startup-config/把start-config文件备份到disk0中，以old-startup-config为文件名第二步：VSS系统配置配置VSS域及设备IDSwitch(config)# switch virtual domain 100/指定交换机1为VSS100区域内的设备Switch(config-vs-domain)# switch 1/指定VSS区域内该交换机的IDSwitch(config-vs-domain)# exit /退出配置模式第三步：VSS系统配置配置VSS逻辑端口和物理端口逻辑端口:Switch-1(config)# interface port-channel 10/启动逻辑接口 Switch-1(config-if)# switch virtual link 1/配置交换ID1使用该逻辑接口Switch-1(config-if)# no shutdown/开启逻辑接口Switch-2(config)# interface port-channel 20 /启动逻辑接口 Switch-2(config-if)# switch virtual link 2/配置交换ID2使用该逻辑接口Switch-2(config-if)# no shutdown/开启逻辑接口物理端口:Switch-1(config)# interface range tenGigabitEthernet 3/1-2/进入需要加入逻辑接口的物理接口Switch-1(config-if)# channel-group 10 mode on/物理接口绑定逻辑接口Switch-1(config-if)# no shutdown/开启物理接口Switch-2(config)# interface range tenGigabitEthernet 5/2-3/进入需要加入逻辑接口的物理接口Switch-2(config-if)# channel-group 20 mode on/物理接口绑定逻辑接口Switch-2(config-if)# no shutdown/开启物理接口第四步：VSS系统配置转换交换机至VSS模式Switch-1# platform hardware vsl pfc mode pfc3c /将PFC模式转换成PFC3CSwitch-2# platform hardware vsl pfc mode pfc3c /将PFC模式转换成PFC3CSwitch-1# switch convert mode virtual/转换交换模式为虚拟交换Switch-2# switch convert mode virtual/转换交换模式为虚拟交换之后会提示重新启动，启动后会自动协商角色第五步：VSS系统配置快速HELLO双活检测配置vss(config)# switch virtual domain 10 vss(config-vs-domain)# dual-active detection fast-hello vss(config-vs-domain)# exit vss(config)# interface fastethernet 1/2/40 vss(config-if)# dual-active fast-hello WARNING: Interface FastEthernet1/2/40 placed in restricted config mode. All extraneous configs removed!vss(config-if)# no shutdown vss# show run interface fastethernet 1/2/40 interface FastEthernet1/2/40 no switchport no ip address dual-active fast-hello end 第六步：VSS系统配置切换回单机运行模式备份VSS配置：Switch-1# copy running-config startup-config Switch-1# copy startup-config disk0:vs-startup-configSwitch-2# copy running-config startup-config Switch-2# copy startup-config disk0:vs-startup-config将设备状态改成单独模式：Switch-1# switch convert mode standaloneSwitch-2# switch convert mode standalone第七部：VSS系统运行维护检查VSS状态信息显示VSS区域，交换机ID，以及状态：Router# 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显示状态，交换ID，VSS系统中每个设备的优先级：Router# show switch virtual roleSwitch Switch Status Preempt Priority Role Session IDNumber Oper(Conf) Oper(Conf) Local Remote-LOCAL 1 UP FALSE(N) 100(100) ACTIVE 0 0REMOTE 2 UP FALSE(N) 100(100) STANDBY 8158 1991In dual-active recovery mode: No显示VSL状态：Router# show switch virtual linkVSL Status: UPVSL Uptime: 4 hours, 26 minutesVSL SCP Ping: Pass OKVSL ICC (Ping): PassVSL Control Link: Te 1/5/1第八步：VSS系统运行维护检查VSS模块状态Router# show module switch 1 | 2 | all 用来显示整个或单个VSS成员上的模块情况Router# show module switch 1 Switch Number: 1 Role: Virtual Switch Active- -Mod Ports Card Type Model Serial No.- - - - - 1 48 CEF720 48 port 10/100/1000mb Ethernet WS-X6748-GE-TX SAL1215M2YA 2 8 CEF720 8 port 10GE with DFC WS-X6708-10GE SAL1215M55F 3 1 Application Control Engine Module ACE20-MOD-K9 SAD120603SU第九步：VSS系统运行维护检查VSS系统冗余状态VSS#sh switch virtual redundancy My Switch Id = 1 Peer Switch Id = 2 Last switchover reason = none Configured Redundancy Mode = sso Operating Redundancy Mode = sso Switch 1 Slot 1 Processor Information : - Current Software state = ACTIVE Uptime in current state = 1 day, 19 hours, 30 minutes Image Version = Cisco IOS Software, s72033_rp Software (s72033_rp-ADVENTERPRISEK9_WAN_DBG-VM), Version 12.2(SIERRA_INTEG_070530) INTERIM SOFTWARE Synced to V122_32_8_11, 12.2(32.8.11)SR on rainier, Weekly 12.2(32.8.11)SX85 Technical Support: /techsupport Copyright (c) 1986-2007 by Cisco Systems, Inc.
