Discovery
Network discovery identifies connected network participants and displays
their broadcast information. All participants found in the subnet
{if possible} are grouped accordingly.
Figure 45 - Network detection {overview}
There are two different ways of discovering network devices using
Set to Passive /
Active Mode
.
•
Active mode:
The NetXpert XG2 uses Active Resolution Protocol (ARP) to
identify devices in the network and displays the received data for each device
available. The NetXpert XG2 sends Ethernet telegrams to the network.
•
Passive mode:
The NetXpert XG2 only "listens" to the network and displays all
broadcasting devices. However, less detailed information about the discovered
devices may be available.
The NetXpert XG2 displays the MAC, IPv4, and IPv6 addresses of each discovered
device as well as the DNS {Domain Name System} and NetBIOS {Network Basic Input
Output System} name. Each device is assigned to a device type. There are 5 groups:
Router, switch, printers, servers and hosts. The NetXpert XG2, however, can only
display the
information that is output by the respective devices. Therefore, reliable assignment to
the device groups cannot always be made.
By tapping on a device group, e.g.
Hosts
, the display changes to the list display, in
which each device found in this assignment is listed individually.
The
Lists/Overview View
button makes it possible to switch between the overview and
list display.
If the device finds duplicate IP addresses in the network, these are highlighted in red.
