How to have a more accurate topology of devices?

Follow

D-View 7 uses both the LLDP (Link Layer Discovery Protocol) and FDB (Forwarding Database) table information to determine the relationship of devices when drawing topology.  The information from the LLDP is more reliable for the topology so if the LLDP is disabled on devices, D-View 7 will rely on information from the FDB table and therefore the topology may not be very accurate.

In most cases, LLDP is disabled in devices.  Hence, we suggest you to enable LLDP in most of devices to make sure the topology can be more accurate.
