Device Discovery Process

When you attach the Network Assistant to a network, it immediately begins searching for servers, routers, printers, and switches. This search occurs whenever the Network Assistant gains link pulse regardless of the current menu.

During the discovery process (5-20 seconds, depending on network), the Network Assistant processes only the discovery response frames and broadcast frames. When the discovery process has finished, the Network Assistant goes into promiscuous mode. In this mode, it processes all frames and reports all stations that talk on the network.

Identifying Routers

The Network Assistant also transmits RIP requests and ICMP router requests as part of its router discovery process. These discovery packets request router information, allowing the Network Assistant to locate routers that have little traffic and are not sending routing updates.
