L2Discover是一款用于发现交换网络第二层拓扑结构的应用程序。主要目标是实现一个简单的桌面应用程序，作为第二层Ping和Traceroute工具来映射当前网络拓扑。它利用了Cisco Discovery Protocol、Spanning Tree Protocol和Filtering Address Base等信息源。

Goals:
The aim of L2Discover is to discover the second layer topology of a switched network.
The main goal was to implement a simple desktop application that can be used as a layer 2
ping and traceroute to map the current network topology.

Features.

As the information source of the topology the following sources have been used:

Cisco Discovery Protocol
If your equipment does not support this protocol the tool will not be able to generate the porper map.

Spanning Tree Protocol (Rapid Spanning Tree Protocol)
This information is used to find the redundant links.

Filtering Address Base
It is used to locate the unmanagable devices on the network.
If situated on a port there are several MAC addresses and the port is not part of the STP or CDP topology then it is highly probable that there is an unmanaged switch or hub.
