How to build network diagram automatically

Starting from the version 3.3, LANState supports the SNMP protocol and can automatically draw network diagram with connections between devices labeled by switch port numbers. Starting from the version 7.0, LANState supports the LLDP protocol.

How to build a network diagram using LANState:

1. SNMP should be enabled on your switches. The program should be allowed in the firewall so it could work with SNMP protocol.

2. Run the Network Map Creation Wizard.

3. Scan network by IP address range. SNMP devices must be inside the scanned IP range.
