Introducing the Network Tracking Database (NetDB) v1.11 with improved third-party device support and Neighbor Discovery protocols CDP/LLDP/FDP. Now available as a VM Appliance.
NetDB keeps track of devices on your network and the status of your switch ports over time. You can map devices to your switch ports, locate ports configured for a VLAN and recover unused switchports and static addresses. NetDB has been designed for use by network teams as well as security teams, helpdesk and the end users of any medium to large network, ultimately reducing support issues. It has been tested with almost every Cisco Ethernet switch, is written in Perl and works on most linux and BSD distributions. It's designed for large campus networks and datacenters, but should work in any environment.
