Network scanning, LLDP and CDP neighbour discovery, read-only SNMP, diagnostics, capture analysis, topology and client reports, in one window.
Packet Haven toolkit
Network discovery, packet analysis and rack documentation for IT prosYour network.
The whole picture.
Find what is connected and which switch port it lives on. Explain what the traffic did. Turn it into documentation somebody else can use. Three tools that follow one investigation, each useful on its own.

Three tools
One network.
Three ways to see it.
A Windows toolkit for the site visit, a browser analyser for the capture, and a documentation model for the room. Use one, or carry the work from one to the next.
Packet Lens
Capture & analyse · Web browser
Open a .pcap or .pcapng in your browser, follow a device through its conversations, and see findings tied to the packets behind them.
Packet Blueprint
Map & document · Web browser
Racks to the exact unit, front and rear, power and PoE, cabling, networks and inventory, on one model stored in your own browser.
A better way to work
From “what’s on here?”
to “here’s what happened.”
- STEP 01
Discover
Packet Echo
Scan the subnet you are authorised to inspect. LLDP and CDP name the switch and port you are plugged into, and read-only SNMP shows what that switch knows.
- STEP 02
Investigate
Packet Echo · Packet Lens
Run the ordered Diagnose check, watch port counters move while a fault is happening, or open a capture and let Packet Lens rebuild the conversations behind a finding.
- STEP 03
Document
Packet Echo · Packet Blueprint
Hand over a branded Site Packet from Packet Echo, and model the room in Blueprint: racks, power, cabling and inventory the next technician can trust.
What’s inside
Everything you need to understand a network.
Every view below is a capture of the shipping software, cropped to areas without private data.
Read-only SNMP switch views
Packet Echo ProInterfaces, MAC-to-port, spanning tree and port health from one read-only connection. Observe takes a baseline and reports the change, which is the number worth acting on.
Which switch port is this jack?
Packet Echo · LLDP & CDPListen for LLDP and CDP and Packet Echo names the neighbouring switch and the exact port this machine is on. No console cable, no hunting for the patch-panel sheet.
Scan, then compare
Packet Echo · comparison in ProAddress, range or CIDR. Hostname, MAC vendor, latency and open ports, and a second scan shows what appeared and what went missing.
Watch it over time
Packet Echo · MonitorContinuous ping against one target: loss, jitter and min / avg / max, while you wait for the fault to come back.

“Why is it slow?” answered in about fifteen seconds
Packet Echo · DiagnoseAn ordered check of local link, internet path, DNS and throughput, ending in a plain-English verdict on the most likely cause.
Packet analysis, with the evidence attached
Packet Lens Web · built into Packet EchoFindings such as unanswered connections and retransmissions, ranked by impact, each one explained and one click from the packets that support it.
Topology that shows its evidence
Packet Echo · Topology StudioDiscovery can infer a link it never saw. The map says which is which, and your notes and layout survive the next rescan.
- Confirmed: both ends agree (LLDP)
- Observed: one side reported it
- Inferred: from MAC learning
- Assumed: no evidence for this path
Racks to the exact unit
Packet BlueprintOver a thousand vendor models, placed at a real unit on the front or rear face. A placement that cannot exist is refused, with the reason.
Inventory, networks and every cable
Packet BlueprintData and power links with ports, labels, types, lengths and VLANs. One device appears in the rack, the topology and the inventory because it is one object.

Where it fits
Built for the work behind the network.
For IT pros, MSPs, consultants, network engineers and small IT teams, and for anyone whose rack outgrew the spreadsheet.
Field technician
“The wall jack isn’t labelled, and the closet is three floors up.”
- Discovery listens for LLDP and CDP and names the switch and port this laptop is on.
- Diagnose runs local link, internet path, DNS and throughput in order, so you know which hop to stop blaming.
- Copy Ticket Note puts a short written summary straight into the ticket.
MSP & consultant
“New client, no documentation, and a two-hour onboarding visit.”
- Scan, then SNMP builds the device list and the switch view during the first visit.
- The Site Packet collects branded reports, CSV and JSON data, and editable topology into one ZIP.
- Blueprint models their rack to the unit, so next quarter’s visit starts from a list that matches the room.
Network engineer
“Intermittent drops, and a capture someone emailed at 2 a.m.”
- Observe takes a port-counter baseline and reports only what changed during the window.
- Packet Lens ranks findings by impact and shows the packets behind each one.
- Topology Studio keeps confirmed links visually distinct from inferred ones.
Homelabber
“The rack grew faster than the spreadsheet did.”
- Packet Blueprint is free: place every device at its exact unit, front and rear.
- Power and PoE show which circuit feeds what, and how much PoE budget is left.
- Packet Echo’s free edition scans the subnet and lists what answered and which ports are open.

Questions
Before you dive in.
Licensing, data handling and what each tool does and does not do. Something missing? Ask us.
Is Packet Lens included with Packet Echo?
Yes, in two ways. The capture analysis engine is built into the Packet Echo Windows app, and a Pro licence also gives you Packet Lens Web in the browser at no extra cost: sign in to your account and open it there. The $5 per person / month membership is for people who want the browser edition without buying Packet Echo.
How does the Packet Echo licence work?
Packet Echo Pro is $79 per person, paid once. A licence covers one technician on up to five of their own machines, and it is perpetual: yours to keep, with no recurring charge. Licensing a team? Choose how many at checkout and each person gets their own key. Validation happens offline: the app contacts us only when you activate a key or choose Check for updates, never on a timer or at startup. Every future version is included.
Does Packet Lens upload my capture?
No. The browser edition analyses the file on your machine and holds it in browser memory, so the practical size limit is the memory you have available. For larger local captures, use the Capture Analysis workspace inside Packet Echo.
Does SNMP change my switch configuration?
No. The switch workspace only reads: system information, interfaces, the bridge MAC table and spanning tree. Nothing in it writes to a device. It supports SNMP v1 and v2c, and what you see depends on what the device exposes to the community you use.
What can I export?
Packet Echo Pro produces branded HTML and PDF reports, CSV and JSON scan data, a ticket note, and topology as editable SVG or draw.io, collected into one Site Packet. Packet Blueprint exports reports, drawings, cable schedules, inventory, bill of materials and label sheets with the Lens + Blueprint membership.
Is Packet Blueprint really free?
The application is: model every rack, cable and device without an account, and take a full backup whenever you like. The membership pays for the documents you hand to somebody else: reports, drawings, schedules, labels, the client viewer and printing. Your diagrams stay in your browser either way.
Are these screenshots from the real applications?
Yes. Every product view on this site is a capture of the actual software. Identifying network details are redacted or replaced with documentation-range example data, and the Packet Lens capture is entirely synthetic.
