The following devices are running with an unsupported version of
the management agent software
For 3Com devices, 3Com Network Director has a minimum supported
agent version. If 3Com Network Director detects a device running an
agent below this minimum it will log this message, since the details it
obtains from the device may not be complete, and the deduced topology
may not be accurate. You should endeavor to update such devices to at
least the minimum version.
The following devices are running with an unknown version of
the management agent software
3Com Network Director logs this message if it cannot determine the
agent software version of a device. It is most likely that the version is
below the minimum supported and the consequence will be that same as
that in the above message. It is also possible that the format used to

3Com Network Director service packs which will support the latest

below the minimum supported by 3Com Network Director.
The exact position of the following devices could not be
determined
This message generally applies to end stations. It results in the devices
being arranged at the top of their submap, unconnected to other devices.
It is possible to disable address learning on certain families of switches,
which can result in 3Com Network Director being unable to determine
the devices they are connected to. The most likely cause of this message,
