What it is
LanTopoLog discovers, maps and monitors physical network topology on a local network. It uses agentless SNMP discovery and presents a searchable, editable map; the maker says it works with any switch model. Its Switch Port Mapper links physical ports to attached devices’ MAC and IP addresses. Monitoring includes traffic, invalid packets and dropped packets, with threshold alerts sent by email, Telegram or Syslog. Reports export to PDF and Draw.io/Diagrams.net. Browser access and remote control are supported, but publishing requires an external web server. The product is listed for Linux, Windows and web use, though Linux has limited functionality. LanTopoLog 2 costs 50.00 USD once for one local network; the license covers up to three bound switches and cannot be renewed. Discovery may miss connections. After some time, the unregistered version disables web publishing, VLAN IDs, traffic charts and search, and shows demo data. A free plan and trial are listed.

Strong points and limits
Strong points
- Agentless SNMP topology discovery
- Editable, searchable topology map
- Alerts via email, Telegram or Syslog
- PDF and Draw.io/Diagrams.net report exports
Limits
- Linux version has limited functionality
- Discovery may leave some connections undiscovered
- Web publishing requires an external server
- LanTopoLog 2 license cannot be renewed
Who it suits
LanTopoLog may suit administrators who need local-network topology discovery, device mapping and traffic monitoring. Its Linux limitations and external web-server requirement matter for teams planning those deployment paths.
Verdict
LanTopoLog combines topology mapping with port identification, monitoring and report exports. The listed one-time license is 50.00 USD, but discovery is not fully reliable and some Linux features are missing.
