This will display the same dialog box as for adding subnets, described above, with the Start and End fields completed with the information you originally supplied. Modify the fields as necessary and select OK to update the range.

To remove ranges from being detected, select the ranges and click Delete.

The ranges will remain in the map but will be unchanged by the Network Discovery process. See “Deleting Items from the Map” on page 204 for details of how to remove devices permanently from the map.

The Retry/Timeout information section of this dialog box allows you to control how long 3Com Network Director waits for a response from a device for the different protocols it uses during discovery and how many times it will retry if it fails to get a response. See “Key Concepts” on page 92 for how the different protocols are used. The use defaults option is checked by default so that the global settings will be used from the Options dialog box. If you uncheck this, the retry/timeout fields become enabled so that you can modify them for this specific subnet. You may wish to change these values from the global default if the subnet you are
