We inherited some really old Dell switches from one of our research/academic departments, but after having insufferable issues just getting a trunk up, gave up on it, reset to factory defaults, and used them as dumb flat-vlan switches for a bit. We are evaluating a number of switches for wireless upgrades and VoIP suitability, trying to generalize a PoE/Gig capable configuration rather than running every special case (APs, cameras, signage, VoIP phones, and everything else that shows up) into their own dedicated corner of the wiring closet with jumpers going everywhere. The PowerConnect 7048P was suggested and we're evaluating a stacked pair. Their general configuration is much more IOS-like (assign vlans at the interface, rather than assigning interfaces at the vlans like HP / Foundry / Brocade / others) and the initial setup looked promising, until we hit the spanning tree issue, and thus my original question. I've floated feedback / inquiries back to the sales team and the techs / consultants they brought with them. So far it's silence on the 7048P and a suggestion of the stackable Force10s as offering better interoperability with out-of-the-box Cisco PVST. They seem compatible with everything we've done testing on other than a lack of PoE+ (not that we necessarily need it for much of anything at this point, but seemed to be a future-proof option to have). I'd rather have the odd switch or two in the closet for the odd PoE+ need or two, than crash the network with a spanning tree meltdown. So the lack of PVST tolerance may well be a show-stopper for Dell networking here unless some other options materialize. We ran into similar issues with Procurves early on, but have almost retired all of those mistakes after some spanning tree issues reared their ugly heads. Of course I'd love to just stack some 3750Xs (stacking data and power) and be done with it, but we're a few truckloads of cash short of that for the access layer (although we remain staunchly Cisco layer-3 at this point). Thanks for all of the feedback and discussion on this topic!
