LanTopoLog

What LanTopoLog is

LanTopoLog discovers, displays, and monitors physical network topology using automatic SNMP discovery. Its searchable, editable map shows network connections, and its Switch Port Mapper links physical switch ports to the MAC and IP addresses of attached devices. The product says it works with any switch model. Monitoring covers network traffic, invalid packets, and dropped packets, with alerts when traffic thresholds are exceeded. Alerts can be sent by email, Telegram, or to a Syslog server. Reports can be exported to PDF and Draw.io/Diagrams.net. Browser access and remote control are available, but web publishing requires an external web server because LanTopoLog cannot act as one. The software is listed for Linux, Windows, and web use; the Linux version has limited functionality. The Java version supports SNMPv3 authorization up to SHA-512 and AES-256. The maker says its portable program does not write to the operating system area or send data elsewhere. LanTopoLog 2 costs $50, paid once for one local network, with up to three bound switches; the license cannot be renewed. The unregistered version disables some features after a time and displays demo data.
