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. The new 9400 only supports StackWise Virtual, which is the same as VSS. VSS on a 9400/9500/9600 only up to TWO units. All line cards in both chassis still continue forwarding. The stack cable can be only up to 3 meters (or 5 meters ) so it is not possible to keep the stack and move a switch in the other server room. Rene. The Cisco StackWise Virtual feature includes the following enhancements in this release: The feature is now supported on the following hardware: Cisco Catalyst 9400 Series Supervisor 1XL 25G Module (C9400-SUP- 1XL -Y) Cisco Catalyst 9400 Series 10 Slot Chassis (C9410R) Supervisor is NOT SUPPORTED (for now). Restartthestandbyswitch. Stackwise Virtual is similar to what other manufacturers call "Stacking-over-Ethernet" or "front-panel stacking" because it uses the Ethernet interfaces on the front of the switch and uses standard optics for connection. For example, Cisco's StackWise Virtual allows you to create a virtual switch with up to eight. There is a outage of 1sec/1Ping. This is similar to the Virtual switching system (VSS) in the traditional 4500,6500 series. check all the hardware and supervisor the same as active. Unlike 3750 stacking, which uses special copper cables, 6500 VSS is done using 10 gig ports which can use the various 10 gig transceivers for those ports (copper or gig). Eso sí, solo dos dispositivos máximo pueden ser parte de un dominio VSS. Stacking transforms standalone switches into single logical unit or group, with this group of switches showing the characteristics of a single switch. Up to 25. It already seemed wonderful to me if the Catalyst 9300 supports stackwise and / or VSS. To update the MAC address on the StackWise virtual domain, execute the command “stack-mac update force. You can configure a StackWise Virtual link on a supported port. vss is old school, depending on the use case, stack cable could do, or if its at the distro / core then nexus vpc would be the newer tech to use. . Some of benefits garnered through Cisco VSS and Juniper VC technology are as under –. StackWise, VSS, and vPC . However, VSS can offer more ports per virtual switch, as each VSS member can have up to 576 ports. Thankfully I was in a maintenance window and. we do in all our regions , core 6509 VSS dist 4500X VSS and even access are VSS 4507 or stackwise 9k and in DC we 7k VPC , we have to remain up at all costs at each layer so for us its important, then you have the extra throughput , single management of core , loop free as you said , no requirement for FHRP , less management. What is the benefit of StackWise virtual? It is simple: The StackWise cables make it easy to virtualize two Cisco Catalyst switches. Stackwise Virtual is a Cisco virtualization technology that allows for two Catalyst 9500 switches to virtually form a single switch, not unlike VSS with other Catalyst platforms. Free CCNP ENCOR 350-401 Flashcard/Labs: ExSim: NetSim: In Cisco StackWise Virtual, the Cisco StackWise Virtual active switch runs the Layer 2 and Layer 3 protocols and features and manages the ports on both the switches. Cisco StackWise Virtual solution supports ISSU. The difference is that the feature known as MEC is found on the Catalyst 6500 VSS switches.
