This is one of those curious half-breed thingys that were popular for a year or so before the prices of switches fell through the floor. It's essentially a 10Base-T hub and a 100Base-TX hub in the same box, a relatively simple switch at each port connects "partitions" you the 10 or 100 mbps portion. They're odd little beasts, you can sniff traffic on them, but only traffic at the same speed you're running at. If you have two 100Base machines yakking away and try to sniff them from a 10Base machine, you won't see anything. These were typically sold as "Dual Speed" hubs, thus the "DS" in the product id. -- Where am I, and what am I doing in this handbasket? Wes Peters wes@softweyr.com
