Running Switch TopN Reports Without the Background Keyword

If you enter the show top command without specifying the background keyword, processing begins but
the system prompt does not reappear on the screen and you cannot enter other commands while the report
is being generated.
You can terminate the Switch TopN process before it finishes by pressing Ctrl-C from the same console
or Telnet session, or by opening a separate console or Telnet session and entering the clear top
[report_num] command. After the Switch TopN Reports utility finishes processing the data, it displays
the output on the screen immediately. The output is not saved.

Running Switch TopN Reports with the Background Keyword

If you enter the show top command and specify the background keyword, processing begins and the
system prompt reappears immediately. When processing completes, Switch TopN reports do not display
immediately on the screen but are saved for later viewing.
The system notifies you when the Switch TopN reports are complete by sending a syslog message to the
screen. Enter the show top report [report_num] command to view the completed Switch TopN reports.
The system displays only those reports that are completed. For reports that are not completed, the system
displays a short description of the Switch TopN process information.
You can terminate a Switch TopN process that is invoked with the background keyword only by entering
the clear top [report_num] command. Pressing Ctrl-C does not terminate the process. Completed
Switch TopN reports remain available for viewing until you remove them by using the clear top {all |
report_num} command.
