Characterizing the Existing Network
Characterizing the network is Step 2 of the design methodology. In this section, you learn to identify a network’s major features, tools to analyze existing network traffic, and tools for auditing and monitoring network traffic.

Steps in Gathering Information
When arriving at a site that has an existing network, you need to obtain all the existing documentation. Sometimes no documented information exists. You should be prepared to use tools to obtain information and get access to log in to the network devices to obtain information.
Here are the steps for gathering information:

When gathering exiting documentation, you look for site information such as site names, site addresses, site contacts, site hours of operation, and building and room access. Network infrastructure information includes locations and types of servers and network devices, data center and closet locations, LAN wiring, WAN technologies and circuit speeds, and power used. Logical network information includes IP addressing, routing protocols, network management, and security access lists used. You need to find out whether voice or video is being used on the network.
