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
