spanning-tree mode rapid-pvst 是一种生成树协议（STP）的模式，它指的是快速PVST（Per-VLAN Spanning Tree）模式。在这种模式下，交换机会为每个VLAN独立运行PVST算法，以加快收敛速度。快速PVST模式旨在减少网络中出现环路的风险，同时提高网络的可靠性和性能。与传统的STP（如STP、RSTP）相比，快速PVST...
PVST：Per-VLAN Spanning Tree（每2113VLAN生成树5261），是解决在虚拟局4102域网上处理生成树的CISCO特有解决方案。Cisco在提出了Portfast，Backbonefast，Uplinkfast等一系列1653spanning－tree特性后，IEEE修改得出了802.1W标准，为和上一代PVST区分，便把有这些特性的spanning－tree称为rapid-pvst。

The Rapid PVST+ protocol is the IEEE 802.1w standard, Rapid Spanning Tree Protocol (RSTP), implemented on a per VLAN basis. Rapid PVST+ interoperates with the IEEE 802.1D standard, which mandates a single STP instance for all VLANs, rather than per VLAN. Rapid PVST+ is enabled by defau...

PVST+ is per-VLAN spanning tree (which is the default for most cisco switches). It means that you will run an spanning-tree instance per VLAN. This is useful when you need different layer 2 behaviors per VLAN, for example you can have different root bridge on different VLANs (so that ...
You generally need to run the same version of spanning tree on all of your network devices. The notable exception being that if you have RSTP and STP, RSTP will see an STP region as a single "device" and give it exactly one functional
