Cisco VSS configuration Commands

Cisco's VSS is similar to H3C's IRF

Step together	6509-1 Configuration
First step, initialize Catalyst 6509 switch	vss-sw1#conf T
	6509-2 Configuration
	vss-sw2#conf T
Step Two, Configure the VSS Domain ID;	VSS-SW1 (config) #switch virtual domain Domain ID + config would take Effect only After the EXEC command ' switch Convert mode virtual ' is issued
	6509-2 Configuration
	Vss-sw2 (config) #switch virtual domain
The third step, Set switch ID;	VSS-SW1 (config-vs-domain) #switch 1
	6509-2 Configuration
	VSS-SW2 (config-vs-domain) #switch 2
Fourth Step, Verify switch ID;	vss-sw1#Switch Read Switch_num Read Switch_num from Rommon is 1
	6509-2 Configuration
	vss-sw2#Switch Read Switch_num Read Switch_num from Rommon is 2
Fifth Step, Configuring 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 Configuration
	vss-sw2#conf T Vss-sw2 (config) #interface Portchannel 2 VSS-SW2 (config-if) #switch Virtual link 2 VSS-SW2 (config-if) #no shut
Physical interfaces are zoned into port groups	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 Configuration
	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
Sixth Step, VSS Mode Conversion	vss-sw1# switch convert mode  virtual this command would convert all 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 building configuration ... [ok] saving converted configurations to bootflash ... [ok]  
	6509-2 configuration
	vss-sw2# switch Convert mode   Virtual this command would 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 building configuration ... [ok] saving converted configurations to bootflash ... [ok]  
Seventh Step, Restarting the switch	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 is now online VSS > vss>en vss# 6509-2 Configuration
	system detected Virtual Switch interface TENGIGABITETHERNET2/5/4 is member of Portchannel 2 interface Tengigabitethernet2/5/5 is member of Portchannel 2 <SNIP> 00:00:26:%vsl_bringup-6- module_up:vsl MODULE in slot 5 switch 2 brought up initializing as Virtual Switch standby &NBSP; 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
Eighth Step, Verifying the VSS Configuration	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
Nineth Step, Master and Standby Configuration synchronization	&NBSP; vss# Switch Accept Mode virtual this command would bring in all VSL configurations from the standby switch and populate it into the running configuration. white Paper all contents is Copyright  1992–2008 Cisco Systems, Inc.

[yes/no]: Yes building configuration ... [ok] &NBSP;
Tenth step, Configuring VSL Failure	(There are two ways:) 1, PAGP 2, BFD
PAGP , it seems that the following access to 4500 above. There was no success in doing the experiment anyway.	vss (config) # Interface Port-channel VSS (config-if) # shutdown VSS (config-if) # Exit vss (config) # switch Virtual domain VSS (config-vs-domain) # dual-active Detection PAgP VSS (config-vs-domain) # dual-active Detection PAGP Trust Channel-group VSS (config-vs-domain) # Exit vss (config) # Interface Port-channel 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 VSS (config-vs-domain) #dual-active detection PAgP VSS (config-vs-domain) #dual-active Trust Channel-group VSS (Config-vs-domain) #
BFD configuration, The experiment was successful.	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 Min_rx-multiplier 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 Min_rx-multiplier VSS (config-if) # no shutdown VSS (config-if) # Exit vss (config) # switch Virtual domain 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 2 55.255.255.0 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
Set priority for two switches	vss#conf t enter configuration commands, one per line. End with cntl/z. vss (config) # switch virtual domain vss (config-vs-domain) # switch 1 priority *jul 7 08:59:11.913:%vslp-sw1_spstby-5-rrp_rt_cfg_change:configured priority value change would take the effect after Config was saved and switch is reloaded. vss (config-vs-domain) # switch 2 priority vss (Config-vs-domain) #^z vss#
11th Step, Save Configuration	vss#conf T Enter configuration commands, one per line. End with cntl/z. VSS (config) #WR
