On the SX2000 you can use the "TYPE" command from the maintenance screen. As my aging memory recalls the command syntax is something like this:
type *.traffic.2006JUL251000
In the above example we would be dumping the traffic logs for July 25, 2006 for the 9A to 10A hour. The systax requires military time, 0000 thru 2400, inclusive.
This also assumes you have traffic reporting enabled for the time period you're interested in.
