Description
This command is used to display the historical statistics count for the packets sent and received by
the switch.There are two kinds of statistics offered, 15-minute based and 1-day based. For
statistics based on 15 minutes, there are five counting slots for the historical statistic count.
Suppose that the system has been up for more than 75 mins, then slot 1 refers to the time since
15 minutes ago until now, and slot 2 refers to the time since 30 minutes ago until 15 minutes ago.
For statistics based on a day, there are two counting slots for the historical statistic count. The
counter for a slot represents statistics count of occurrence in that time slot.
