STP Viewer: Free Software Tool for Viewing and Analyzing STP Network Protocol Data
Load capture files, inspect STP frames and BPDUs, analyze STP topology and events, and gain insights into Spanning Tree operations with this free software tool.
What is STP Viewer?
STP Viewer is a specialized software tool for network engineers and administrators to visualize and analyze the Spanning Tree Protocol (STP). It provides an intuitive graphical interface to load network packet capture files (PCAPs), inspect Bridge Protocol Data Units (BPDUs) and STP frames, study STP topology and events, identify issues and understand root cause.
Key features of STP Viewer include:
- Graphical network topology visualization showing STP root bridges, designated bridges/ports, blocking ports etc.
- Detailed decoding and inspection of BPDU frames and fields like bridge ID, port role, port state etc.
- Timeline view correlating STP events like topology changes, port role changes with network events
- Convergence analysis during events like bridge failure, link failure, topology change
- What-if scenario modeling by simulating failure/recovery of bridges, links, LAN segments
- Report generation summarizing the STP analysis
STP Viewer helps network engineers analyze and troubleshoot STP issues like suboptimal topology, frequent topology changes, undesirable blocking ports. It can also be used during pre-deployment testing and validation of STP designs. The software runs on Windows and Linux platforms and supports PCAP files from various packet capture tools.
