Under MSTP, a spanning tree can be defined for individual VLANs or for groups of VLANs. Furthermore, the administrator can define alternate paths within a spanning tree. Switches are first assigned to an MST region, then VLANs are mapped against or assigned to this MST.

2014年8月15日 · Spanning Tree Protocol (STP) 是一款 Layer 2 的 Protocol，一般在 Switch 上執行，主要目的是防止 Switch 在接駁時產生 Switching Loop。 STP 是在學習網絡知識中一個重要的課題，必需深入了解其運作原理和操作流程。

2024年11月26日 · The Meraki documentation provides an overview of Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol(RSTP) configuration ensuring network stability and preventing loops.

2025年3月21日 · This tutorial explains the Spanning Tree Protocol in detail. Learn how to configure, test, and verify STP through a packet tracer example.

Spanning Tree Protocol (STP) ensures a loop-free topology in a local area network (LAN) made up of switches. It is desirable to have redundant links in a switched LAN so that a single link failure cannot interrupt normal operation of the network.

2025年2月16日 · STP 的主要目的是防止网络中出现环路，通过选举一个根网桥（Root Bridge），以及在其他网桥之间计算出无环的路径来实现。 根网桥是整个生成树的核心，其他网桥根据到根网桥的路径成本来选择根端口和指定端口。 配置过程如下（以华为 S3700 系列交换机为例）： 进入全局配置模式： sysname Switch. 开启 STP 功能： stp enable. 可选配置，修改根网桥优先级（默认优先级为 32768，数值越小优先级越高）： stp priority 4096. 拓扑图示例： 假 …

2022年9月21日 · The Switch is a network device that is used to segment the networks into different subnetworks called subnets or LAN segments. It is responsible for filtering and forwarding the packets between LAN segments based on MAC address. Switches have many ports, and when data arrives at any port, the desti

This chapter describes how to configure the Spanning Tree Protocol (STP) on port-based VLANs on the Catalyst 2960 and 2960-S switches. The switch can use either the per-VLAN spanning-tree plus (PVST+) protocol based on the IEEE 802.1D standard and …

4 天之前 · Key Terms in STP Bridge: A network device (switch) that connects multiple LAN segments. Bridge ID: A unique identifier for each switch, combining the priority (2 bytes) and MAC address (6 bytes). Root Bridge: The switch with the lowest Bridge ID, serving as the central reference for path calculations. BPDU (Bridge Protocol Data Unit): Messages exchanged between switches to share network ...

Spanning Tree Protocol, or STP is an important part of Layer 2 networking. STP is virtually ubiquitous in switches of all types, including both managed and unmanaged devices from a multitude of vendors. Over the years, various newer versions of the protocol have been introduced, further refining, perfecting, and accelerating…
