How does autoAsset discover the network?
The Codima Discovery Engine associated with the autoAsset starts the discovery from a seed-device, which must be SNMP-capable. The Codima Discovery Engine will inspect the ARP table, Routing and Forwarding Tables for the seed-device to see who is communicating with whom and then start to interrogate those devices. As it finds the next switch or router it starts to see more devices and the discovery process works in a recursive manner until it sees all active devices. As ARP tables get flushed after 5 minutes by default, the Discovery Engine can force those tables to be populated by using a controlled ping scan of the network and that way also discover connected devices that have not been recently active. We strongly recommend using a router as the seed-device as this will have the most reliable and extensive ARP table and typically will have most devices on the network in its ARP table. The Discovery Engine then goes on to interrogate the devices using a number of protocols including S
