Sample files
Real tools. Safe examples.

An actual Packet Echo topology export with anonymised device labels. Inspect the editable SVG and its legend separating confirmed, observed, inferred and assumed links.
Pick the right starting point
What are you trying to learn?
What is on this network?
Start with the Packet Echo network scanner. Scan only the scope you are authorised to inspect, then review responding hosts and open ports. A scan is a point-in-time observation, so keep its context with your report.
Explore discoveryWhich switch port is this?
Use Discovery to hear LLDP or CDP from the switch you are plugged into. For the rest of the switch, the read-only SNMP workspace maps MAC addresses to ports; review the evidence before treating an inferred link as confirmed.
Explore LLDP and SNMPWhat happened in the capture?
Open it in Packet Lens. Review the overview, focus on a device or conversation, then inspect the packets behind a finding. A capture only sees the traffic available at its capture point.
