WebLearning. 设备会根据收到的用户流量构建MAC地址表,但不转发用户流量。 ... RSTP的状态规范把原来的5种状态缩减为3种。根据端口是否转发用户流量和学习MAC地址来划分: 如果不转发用户流量也不学习MAC地址,那么端口状态就是Discarding状态。 ... WebApr 13, 2024 · The states are discarding, learning, and forwarding. Unlike STP, which has five port states, RSTP simplifies the state transitions and eliminates the blocking and listening states.
Introduction of Spanning Tree Protocol (STP) - GeeksforGeeks
Rapid Spanning Tree Protocol (RSTP; IEEE 802.1w) can be seen as an evolution of the 802.1D standard more than a revolution. The 802.1D terminology remains primarily the same. Most parameters have been left unchanged so users familiar with 802.1D can rapidly configure the new protocol comfortably. See more This document provides information about the enhancements added by RSTP to the previous 802.1D standard. The 802.1D Spanning Tree Protocol (STP) standard was designed at a … See more This table shows the support of RSTP in Catalyst switches, and the minimum software required for that support. See more Few changes have been introduced by RSTP to the BPDU format. Only two flags, Topology Change (TC) and TC Acknowledgment (TCA), are defined in 802.1D. However, … See more The 802.1D is defined in these five different port states: 1. disabled 2. listening 3. learning 4. blocking 5. forwarding See the … See more WebNov 13, 2024 · Rapid Spanning Tree Protocol (RSTP), originally defined in IEEE 802.1w and later merged into IEEE 802.1D, facilitates faster spanning-tree convergence after a topology change. ... Specifies the number of seconds an interface waits before changing from spanning-tree learning and listening states to the forwarding state. Enter a value from 4 ... burt michigan map
RSTP vs STP: Spanning Tree Types and Differences - LinkedIn
WebMar 31, 2024 · In RSTP, the following flag bits are used: Bit 0 for TCN Bit 1 for Proposal Bits 2 and 3 for Port role Bit 4 for Learning Bit 5 for forwarding Bit 6 for Agreement Bit 7 for TCN: Same as RSTP. 9: In STP, the root bridge is the only one that sends BPDUs. Others then transfer BPDUs (Bridge protocol data units). All bridges in RSTP are capable of ... WebMar 6, 2024 · Sorry for the mistake, i intended to ask about learning state in rstp. 01-15-2009 07:25 PM. In that case it directly transitions from discarding to learning. (eg:newly elected … WebSpanning tree protocol (STP) is a network protocol that helps achieve a loop-free topology. The main function of STP is to allow network administrators to manipulate networks paths while preventing bridge (switch) loops. hampton house towson
