3Com Network Supervisor Discovery
When using 3Com Network Supervisor with previous
versions of the software, 3Com Network Supervisor
was unable to display the unit on the network
topology. This will prevent you from using 3Com
Network Supervisor to update the software from 1.00
or 1.01.
This has been fixed. The Switch running software
version 1.02 and above can be discovered successfully
using 3Com Network Supervisor and the correct
network topology generated.
