VSS知识点

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
	6509-2配置
	VSS-sw2(config)#switch virtual  domain 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_num Read switch_num from rommon is 1
	6509-2配置
	VSS-sw2#switch read switch_num Read switch_num from rommon is 2
第五步、 配置VSL；	VSS-sw1#conf t VSS-sw1(config)#interface portchannel 1 VSS-sw1(config-if)#switch virtual link 1 VSS-sw1(config-if)#no shut
	6509-2配置
	VSS-sw2#conf t 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
	6509-2配置
	VSS-sw2(config)#interface range tenGigabitEthernet 5/4 - 5 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 … [OK]
	6509-2配置
	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 startupconfig and reload the switch. Do you want to proceed? [yes/no]: yes Converting interface names Building configuration... [OK] Saving converted configurations to bootflash… [OK]
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 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#   6509-2配置
	System detected Virtual Switch configuration... Interface TenGigabitEthernet2/5/4 is member of PortChannel 2 Interface TenGigabitEthernet2/5/5 is member of PortChannel 2 00:00:26: %VSL_BRINGUP-6- MODULE_UP: VSL module in slot 5 switch 2 brought up Initializing as Virtual Switch standby   00:01:43: %CRYPTO-6-ISAKMP_ON_OFF: ISAKMP is OFF 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.

Page 27 of 80 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. . . Building configuration... [OK]
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)# interface port-channel 20 vss(config-if)# no shutdown vss(config-if)# exit 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-if)# bfd interval 100 min_rx 100 multiplier 50 vss(config-if)# no shutdown vss(config-if)# exit 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-vs-domain)# exit 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#conf t Enter configuration commands, one per line. End with CNTL/Z. vss(config)#switch virtual domain 100 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#conf t Enter configuration commands, one per line. End with CNTL/Z. vss(config)#wr
