CISCO 6500 VSS 配置全过程.doc

VSS Configure1.定义domain-ID范围1-255On Switch 1: podx-vss-sw1#conf t Enter configuration commands, one per line. End with CNTL/Z. podx-vss-sw1(config)#switch virtual domain x Domain ID 1 config will take effect only after the exec command switch convert mode virtual is issued podx-vss-sw1(config-vs-domain)#switch 1 podx-vss-sw1(config-vs-domain)# On Switch 2:podx-vss-sw2#conf t Enter configuration commands, one per line. End with CNTL/Z. podx-vss-sw2(config)#switch virtual domain x Domain ID 1 config will take effect only after the exec command switch convert mode virtual is issued podx-vss-sw2(config-vs-domain)#switch 2 podx-vss-sw2(config-vs-domain)#2.定义优先级-越大越优先On Switch 1:pod1-vss-sw1(config-vs-domain)#switch 1 priority 110 pod1-vss-sw1(config-vs-domain)#switch 2 priority 100 On Switch 2:pod1-vss-sw2(config-vs-domain)#switch 1 priority 110 pod1-vss-sw2(config-vs-domain)#switch 2 priority 100 3.配置Virtual Switch Link (VSL)-最多8个10GE口捆绑(必须用10GE口） 控制面板通过VSL实现两个机箱的CPU到CPU的通讯，数据面板通过VSL扩展本机箱的交换矩阵到远端。On Switch 1: pod1-vss-sw1(config)#interface port-channel 1 pod1-vss-sw1(config)#no shut pod1-vss-sw1(config-if)#switch virtual link 1 pod1-vss-sw1(config-if)#exit pod1-vss-sw1(config)#interface range tenGigabitEthernet 1/4 - 5 pod1-vss-sw1(config-if-range)#no shut pod1-vss-sw1(config-if-range)#channel-group 1 mode on pod1-vss-sw1(config-if-range)#Z On Switch 2: pod1-vss-sw2(config)#int port-channel 2 pod1-vss-sw2(config-if)#no shut pod1-vss-sw2(config-if)#switch virtual link 2 pod1-vss-sw2(config-if)#exit pod1-vss-sw2(config)#interface range tenGigabitEthernet 1/4 - 5 pod1-vss-sw2(config-if-range)#no shut pod1-vss-sw2(config-if-range)#channel-group 2 mode on pod1-vss-sw2(config-if-range)#Z 4.执行转换-转换完记得重启(重启不分先后可独立完成）,重启后端口命名变成三级编码，switch2的console不在可用，所有控制都通过switch1来做On Switch 1: pod1-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 startup-config and reload the switch. Do you want to proceed? yes/no: yes Converting interface names Building configuration. On Switch 2: pod1-vss-sw2#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 startup-config and reload the switch. Do you want to proceed? yes/no: yes Converting interface names Building configuration. 5.在SWITCH1 上对switch2的VSL作最终配置（注意这里不能用range）pod1-vss-sw1(config)#interface port-channel 2 pod1-vss-sw1(config-if)#no shut pod1-vss-sw1(config-if)#switch virtual link 2 pod1-vss-sw1(config-if)#exit pod1-vss-sw1(config)#interface tenGigabitEthernet 2/1/4 pod1-vss-sw1(config-if)#channel-group 2 mode on pod1-vss-sw1(config-if)#exit pod1-vss-sw1(config)#interface tenGigabitEthernet 2/1/5 pod1-vss-sw1(config-if)#channel-group 2 mode on 6.到此为止两台65已经一台了，可以改名并保存配置podx-vss-sw1#conf t Enter configuration commands, one per line. End with CNTL/Z. podx-vss-sw1(config)#hostname podx-vss podx-vss(config)#Z podx-vss# 00:13:40: %SYS-5-CONFIG_I: Configured from console by console podx-vss# podx-vss#wr Building configuration. 00:16:23: %PFINIT-SP-5-CONFIG_SYNC: Syncing the startup configuration to the standby Router. OK podx-vss# 至此VSS配置全部完成！7.查看VSS 状态1） pod1-vss#sh module switch 1 Switch Number: 1 Role: Virtual Switch Active - - Mod Ports Card Type Model Serial No. - - - - - 1 5 Supervisor Engine 720 10GE (Active) WS-S720-10G SAD104707A7 2 4 CEF720 4 port 10-Gigabit Ethernet WS-X6704-10GE SAL1104F8T3 3 48 CEF720 48 port 10/100/1000mb Ethernet WS-X6748-GE-TX SAD074102UP 2）pod1-vss#sh module switch 2 Switch Number: 2 Role: Virtual Switch Standby - - Mod Ports Card Type Model Serial No. 1 5 Supervisor Engine 720 10GE (Hot) WS-S720-10G SAD1047078E 2 4 CEF720 4 port 10-Gigabit Ethernet WS-X6704-10GE SAL1103EERS 3 48 CEF720 48 port 10/100/1000mb Ethernet WS-X6748-GE-TX SAD074206UM 3）pod1-vss#sh run switch 1 Building configuration.
