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. A pair of Catalyst 9500 switches on the other hand using StackWise Virtual, or VSS are much more resistant to such outages or failures. In response to Joe Ank. Fast Hello dual-active detection is supported only on supervisor module ports. Stackwise Virtual の概要. Eso sí, solo dos dispositivos máximo pueden ser parte de un dominio VSS. StackWise Virtual link is the link that connects the switches over Ethernet. 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. LACP is standard and used pretty much by all vendors. Just deployed a pair of these (Catalyst 9500-40-X-A) for a small core at my work about 11 days ago. There are two Virtual Stackwise Links of 10G as part of the SVL domain 1. Step 5: end. It enables stack fabric communication over network ports to. So, the same thing but a different name. Better link utilization, loop-free topology for L2 connectivity. The VSS – Cisco Virtual Switching System is a clustering technology that pools two Cisco Catalyst 4500-E Series Switches with Cisco Catalyst Supervisor Engine 7-E or 7-LE or two Catalyst 4500-X Series Switches into a single virtual switch. Introduction. The defaultvalueisone. We would like to show you a description here but the site won’t allow us. Please give brief explain of the both feature comparison in deep. VIP Alumni. The StackWise-480 is an old technology of Cisco switches stacking, which needs stack cables and kits. I had a weird behavior with my switches. As far as timeframe, the best I can say is that it is planned for end of July at this point, but that is subject to change as roadmap items always are. Bias-Free Language. Interesting to note that before the VSS conversion process proceeds two stand-alone switches are connected together using the same port-channel number. In a single StackWise Virtual domain, one of the switches will be active and one will be on standby. dual-active detection pagp Example: Step10 Device(config-stackwise-virtual)#dual-active detectionpagp Enablesdual-activedetectiontrustmodeon channel-groupwiththeconfiguredID. Used for redundancy / failover. € Traffic going through SWITCH-2 starts going through SWITCH-1 if downstream network is connected via a multi chassis. This white paper talks in detail about the benefits. HTH. Cisco's documentation is not very clear on this.
