Setting up ports for OS fingerprinting

BMC Discovery maintains a list of the port numbers that it interrogates. These ports are scanned only if the Use IP Fingerprinting to Identify OS option is enabled. For more information about this option, see Configuring discovery settings.

If you want to set up additional ports, you must enter this here (for example, if you use a nonstandard port number).

The following topics are covered in this section:
