Using Top-N Reports Chapter 52 Using Top-N Reports Table 52-1 Valid Top-N Statistic Types Statistic Type broadcast bytes errors multicast overflow packets utilization Definition Number of input/output broadcast packets Number of input/output bytes Number of input errors Number of input/output multicast packets Number of buffer overflows Number of input/output packets Utilization Note When calculating the port utilization, Top-N reports bundles the Tx and Rx lines into the same counter and also looks at the full-duplex bandwidth when calculating the percentage of utilization. For example, a Gigabit Ethernet port would be 2000-Mbps full duplex. Understanding Top-N Reports Operation When you enter the collect top command, processing begins and the system prompt reappears immediately. When processing completes, the reports are not displayed immediately on the screen; the reports are saved for later viewing. The Top-N reports notify you when the reports are complete by sending a syslog message to the screen. To view the completed reports, enter the show top counters interface report command. Only completed reports are displayed. For reports that are not completed, there is a short description of the process information. To terminate a Top-N reports process, enter the clear top counters interface report command. Pressing Ctrl-C does not terminate Top-N reports processes. The completed reports remain available for viewing until you remove them by entering the clear top counters interface report {all | report_num} command.
