7.3 Topology Discovery
The table on the “LLDP” tab page shows you the collected LLDP information
for neighboring devices. This information enables the network management
station to map the structure of your network.
Activating “Display FDB entries” below the table allows you to add entries for
devices without active LLDP support to the table. In this case, the device also
includes information from its FDB (forwarding database).
If several devices are connected to one port, for example via a hub, the table
will contain one line for each connected device.
When devices both with and without an active topology discovery function
are connected to a port, the topology table hides the devices without active
topology discovery.
When only devices without active topology recognition are connected to a
port, the table will contain one line for this port to represent all devices. This
line contains the number of connected devices.
You can find the MAC addresses of devices, which the topology table hides
for clarity's sake, in the address table (FDB), (see on page 61 “Filters for
MAC addresses”).
