What are the benefits of Packet Tracer?

Packet Tracer offers an effective, interactive environment for learning networking concepts and protocols. Most importantly, Packet Tracer helps students and instructors create their own virtual “network worlds” for exploration, experimentation, and explanation of networking concepts and technologies.

What are the information that can be obtained from a packet capture?

Packets are captured and examined to help diagnose and solve network problems such as: Identifying security threats. Troubleshooting undesirable network behaviors. Identifying network congestion.

How many packets are in the trace?
