A StackWise Virtual link also transports system data, such as NetFlow export data and SNMP data, from the Cisco StackWise Virtual standby switch to the Cisco StackWise Virtual active switch. (risk is single supervisor running for now until failed one replaced) - depends on criticality of the business choose how many supervisor required. Each switch had created a second provisioning switch and the interfaces wouldn't take the stackwise command while in provisioning mode. this is because a 9k4-5-6 is mostly used in aggregation or core layers, where multiple devices' purpose is mostly to provide redundancy, not connectivity (port density). The upgraded Sup will NOT fully boot the line cards until AFTER the active, lower revision, Sup goes offline to reboot. The Differentiation between both the feature set is tabled below –. In a single StackWise Virtual domain, one of the switches will be active and one will be on standby. A VSS pair is connected by a VSL (virtual switch link). I am replacing these with Cat9ks that support StackWise Virtual. For more information, see the Configuring Cisco StackWise Virtual chapter in this guide. There's no support for more than two switches in either technology. 16.

ISSU is supported in dual SUP HA and StackWise Virtual system. What type of switches are you planning to use for access and what type for core? HTH Cisco VSS. Stackwise/Stackwise Virtual are only for appliances running IOS-XE. VSS (IOS or IOS-XE) is generally stable but is highly dependent on. There is no differece (OLD wine in new Bottle) in terms of operation. Usually with traditional VSS, when one sup fails the sup in the other chassis will take over and not the second sup in the same chassis. we have done several VSS replacements and also SVL recently. It also explains how to troubleshoot common issues and upgrade the software. However, VSS can offer more ports per virtual switch, as each VSS member can have up to 576 ports. e. 带来的好处: -单一的控制管理平面 -分布式数据转发平面,, 增加流量带宽 -高网络可用性 -简化网络架构 配置Stackwise. The logical side of VSS simplifies the network topology. StackWise Virtual offers capabilities similar to Cisco Catalyst 6K/4K VSS in its initial phase.
