The pro for me is that I don't have to deal too much with STP when it comes to access layer switches with duel fiber runs connecting to each core. Configuration performed on both switches: 1st: conf t stackwise-virtual domain 2 end. This is shown in the configuration, even if it the default. BTW, the 9410 does not support VSS (Stackwise Virtual) yet but since you are using 9407, you are. This is expected behavior. To configure SWV on Cisco 9500, first we need to enable the functionality and assign a domain to the switch: ! stackwise-virtual domain 100 ! Domains need to match on all the switches participating in SWV! For SWV to be work, we need to assign the proper configuration to a minimum of two interfaces, but it is. Both the Stack Wise virtual switches are. How does new StackWise Virtual technology compare to Cisco 6K/4K VSS technology? A The initial phase of StackWise Virtual capabilities offers consistent capabilities as a Cisco Catalyst 6K/4K VSS solution. Both VPC and VSS are used basically to support multi-chassis ether-channel that means we can create a port-channel whose one end is device A, however, another end is physically connected to 2 different physical switches which logically appears to be one switch.
