I like to determine the daily bandwidth used by devices connected to the port of the switch. The config utility gives me the port statistics. I think the numbers are cumulative. I know that I can get the daily usage by clearing the data every day first. I was wondering if there is any further control provided by the utility? or other software that allows me to specify the statistic collection period?  For example, I just need the usage between 6 pm to 12 pm on a particular day?
