9.17 Topology Discovery
Devices in networks send notifications in the form of packets which are also
known as "LLDPDU" (LLDP data units). The data that is sent and received
via LLDPDU are useful for many reasons. Thus the device detects which
devices in the network are neighbors and via which ports they are connected.
The tabs of this dialog allow you to display the network and to detect the
connected devices along with their specific features.
This dialog displays the collected LLDP information for the neighboring
devices. This information enables the network management station to map
the structure of your network.
When devices both with and without an active topology discovery function
are connected to a device port, the topology table hides the devices without
active topology discovery.
When devices without active topology discovery are connected to a device
port exclusively, the table will contain one line for this port to represent all
devices. This line contains the number of connected devices.
The Forwarding Database (FDB) address table contains MAC addresses of
devices that the topology table hides for the sake of clarity.
If you use 1 port to connect several devices, for example via a hub, the table
contains 1 line for each connected device.
