The command has optional values (in the range of 1 to 4) that define the level of detail (see table 7).

Table 7. Values defining detail of the queuing statistics

Optional Value Implication on Command Output

0Statistic gathering is switched off

1Display amount of packets passed (did not have to wait), queued (arrived ear- lier than rate permitted) and discarded (due to overflowing queue)

2Also collects byte counts for the catego- ries listed above

3Also keeps track of the peek queue lengths ever reached since the last con- figuration change or reload

4Adds delay time monitoring

Note The debug features offered by SmartWare require the CPU resources of your SmartNode. Therefore do not enable statistic gathering or other debug fea- tures if it is not necessary. Disable any debug feature after use with the no form of the command.

You can enable queue statistics for all queues of a link scheduler by placing the debug queue statistics com- mand in the profile header. Queue statistics are reset whenever the configuration is changed or SmartWare is reloaded.
