In this article I’ll explain how to configure Dual-Active Detection. . 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. When designing the uplink/downlink connections between a pair of C6509 switches configured in VSS domain and a pair of C9606 configured is SV (StackWise Virtual) domain, which option is preferable: option 1 or option 2? Note: If you aren't familiar with the SV technology, imagine having two VSS domains instead. Once completed, the two C9600 switches are available in Quad-Supervisor Stackwise Virtual setup. StackWise cable connection problems are usually caused by a loose connection, not a defect in the cable. This is an important function of VSS because it prevents both supervisors from becoming active in event of a VSL link failure. 基本情況:. They are configured with stackwise-virtual on ports Te1/0/15, Te1/0/16 and Te2/0/15, Te2/0/16. The 9300X is fast. It is a method to handle multiple signals simultaneously. the stackwise virtual name is misleading read it as VSS ---> only two devices can be put together in a SVL pair. 1. Now Cisco 9K series switches comes with the Stackwise virtual in stead of VSS ( which is same concept technically). what happens to the former active switch. Eso sí, solo dos dispositivos máximo pueden ser parte de un dominio VSS. Also,. Lately I've been configuring and deploying a lot of Cisco Catalyst 9K series switches. Used in switches such as Catalyst 9000. Its just the same as regular stacking in that you can configure cross-chassis port-channels (MECs). VSS is configuring 2 devices so that they appear as a single virtual device - Used for larger switches in a network core, provides redundancy etc VPC is configuring a single device. There's no support for more than two switches in either technology. Example: Device(config-if)#end: Returns to privileged EXEC mode. However, the StackWise Virtual technology is a new innovation that is extended based on tradi.

A The initial phase of StackWise Virtual capabilities offers consistent capabilities as a Cisco Catalyst 6K/4K VSS solution. Se interconectan a través de un portchannel configurado en los dos dispositivos que recibe el nombe de Virtual Switch Link (VSL). BB, Let me explain more details, previously we had a stackwise 2 switches and 2 ports of port-channel connected to vendor and upstream load-balance worked equally, but after changed stackwise virtual then 2 switches 2 ports of port-channel members only 1 is sending traffic and other one is none, so load-balance is not working on the port. No, this is not like VSS that you need 2 different Portchannels with 2 different numbers. Stacking (known in the Cisco vernacular as StackWise) is a different beast altogether. It already seemed wonderful to me if the Catalyst 9300 supports stackwise and / or VSS. You have to reboot the switch via redundancy force-switchover. Cisco ® Catalyst ® 9000 platform StackWise ® Virtual technology allows the clustering of two physical switches together into a single logical entity. So much for being "hitless". So, no StackWise virtual/VSS there only stacking with a short cable. It is used during VSS boot up to identify a switch within a VSS domain. Used in switches such as 3750.
