Description:

Netdisco is a Web-based network management tool. Users can locate
the switch port of an end-user system by IP or MAC address. Data
is stored using a SQL database. Cisco Discovery Protocol (CDP)
optionally provides automatic discovery of the network topology.
The network is inventoried by both device model and operating
system (like IOS). It uses router ARP tables and L2 switch MAC
forwarding tables to locate nodes on physical ports and track them
by their IP addresses. For each node, a time stamped history of
the ports it has visited and the IP addresses it has used is
maintained. It gets all its data, including CDP topology
information, with SNMP polls and DNS queries. Security features
include a wire-side Wireless Access Point (AP) locator.
