How does the discovery process work? How does the discovery process work?
The Discovery Engine uses a variety of techniques to discover devices, such as inspection of ARP tables, Routing and Forwarding tables and controlled scanning techniques. This overcomes a limitation of many existing approaches, which need to know what to discover in order to draw a network. Once discovered, devices are queried using SNMP for MIB 2 and current vendor MIBs. WMI is also supported. The autoMap™ has a Device database covering most current and many old generation equipment types. The protocols used in the process include SNMP, ICMP, xDP (Cisco, Cabletron and Extreme Discovery Protocols), NetBIOS, and STP, the discovery process is an active function. To obtain WMI information autoMap™ must be run from a Domain Administrator account. You should enable as many SNMP Agents as possible prior to running the discovery, and consider the firewall configuration on your network and the impact on the discovery process.
