community strings already stored against it in the database
2 It will then attempt to use the community strings you provide in this pane
of the wizard

community for all devices is public, and the default write community
string depends upon the device type. If 3Com Network Director
successfully establishes the read community string then it will be able to
deduce the type of device and consequently know what the default write

If you are discovering the subnet for the first time (that is, not a
