2018年12月13日 · To configure the STP protocol to run on the switch, enter the following: The options are: stp — Classic STP provides a single path between any two endpoints, eliminating and preventing networking loops. rstp — RSTP detects network topologies to provide faster convergence of the spanning tree. This option is enabled by default.

Cisco introduced several enhancements to the standard STP operation that were later incorporated in Rapid Spanning Tree Protocol (RSTP) defined as IEEE 802.1w. We will focus on Spanning Tree Protocol (STP) configuration and verification commands in this tutorial, as implemented on Cisco switches.

This chapter describes how to configure the Spanning Tree Protocol (STP) on port-based VLANs on the Catalyst 2960 and 2960-S switches.

Spanning Tree Protocol (STP) is a Layer 2 link management protocol that provides path redundancy while preventing loops in the network. For a Layer 2 Ethernet network to function properly, only one active path can exist between any two stations. Multiple active paths among end stations cause loops in the network.

2022年12月6日 · 与众多协议的发展过程一样，生成树协议也是随着网络的发展而不断更新的，从最初的 IEEE 802.1D中定义的STP到IEEE 802.1W中定义的快速 生成树协议 RSTP（Rapid Spanning Tree Protocol），再到最新的IEEE 802.1S中定义的多生成树协议MSTP（Multiple Spanning Tree Protocol）。 解决二层环路以下问题： 端口状态为Down，不处理BPDU报文，也不转发用户流量。 过渡状态，开始生成树计算，端口可以接收和发送BPDU，但不转发用户流量 …

The Spanning Tree Protocol (STP) is defined by IEEE standard 802.1D-1988. The STP generates a single spanning tree inside a network. Such mode proved to be useful for supporting applications and protocols in which frames are delivered out of sequence or as duplicates.

When you configure STP or RSTP, you specify the extended system identifier. The default spanning-tree protocol for devices that support Enhanced Layer 2 Software (ELS) is Rapid Spanning Tree Protocol (RSTP). RSTP provides faster convergence times than the original Spanning Tree Protocol (STP).

2016年1月4日 · Spanning Tree Protocol (STP) is a Layer 2 protocol that runs on switches. It was first introduced as CST (Common Spanning Protocol) then IEEE introduced its advanced version as STP with specification IEEE 802.1D. The main purpose of STP is to ensure that switches do not create loops when they have redundant paths in a network. Concepts:

Configuring STP By default, RSTP is enabled on all switch ports.This section provides a procedure for configuring STP (Table 3).To configure other modes, see "Configuring RSTP" on page 8 or
