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...
第一条配置指令是将生成树模式从默认的STP切换至RSTP（快速生成树），以加速网络收敛过程。第二条配置是启动接口的portfast特性，这可以让未连接至其他交换机的端口迅速进入转发状态，无需经过初始的侦听和学习阶段。然而，为了防止在这些快速转发的端口上意外连接了其他交换机，导致可能的环路问题，需要启用b...
第一条是把交换机的生成树模式由默认的STP改成RSTP（快速生成树），第二条是将交换机的接口启动portfast，这样可以使不连交换机类的接口快速转发，但是又为了防止你在该接口接了交换机类导致环路的设备，还需要开启bpduguard，这样就可以忽略从该接口上收到的BPDU。PVST：Per-VLAN Spanning Tree（每2113...

Rapid Per VLAN Spanning Tree Plus (RPVST+) Protocol – Cisco-proprietary enhancement to the IEEE 802.1w RSTP. Similar to PVST+, it enables us to create a one spanning-tree instance per VLAN as well. Network convergence is also faster with RPVST+. Single Spanning Tree vs Multiple Spanning ...

Each Rapid PVST+ instance on a VLAN has a single root switch. You can enable and disable STP on a per-VLAN basis when you are running Rapid PVST+. PVRST uses point-to-point wiring to provide rapid convergence of the spanning tree. The spanning tree reconfiguration can ...
