I noticed the only "L3 support" from the spec sheets of the 4000M and 8000M is IGMP snooping to control multicast traffic, and "protocol filtering" only on the 8000M. Nothing close to IP routing, however (not that you said it did, specifically, just clarifying). When the Tolly Group said they could "sustain full wire speed on all 40 ports", was that testing each one at a time or all at once? My math isn't quite warped enough to allow 40 100Mbit/FD ports to all be saturated with only a 3.8Gbit backplane, unless local switching occurs on each of the port modules, and even then the "throughput test" would have to take that into account and not try to move too much data across the backplane. You may also notice that the HP ProCurve 9304M and 9308M Routing Switches (these DO have IP/IPX routing, but they certainly aren't cheap... nice kit, BTW), bear an uncanny resemblance in both looks, specs, and a digit of their model name to the Foundry Networks BigIron 4000 and 8000, respectively. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
