All switching is done in layer2! Layer3 switch 'features' (functionality) is was the vendor put in the box. Depending on the amount of $ you're going to spent, you can have switches that can act as routers. > > I see the HP Procurve 2626 (I don't need 50 ports yet) for ~$600 on > the web ... while I can pick up the Dell PowerConnect 3324 is ~$500 > ... > > How do I compare the two?

The mpps is normally what the switch can do in total / back-plan back-bone or whatever the vendor want to call it. > > Based on the #s for throughput, I can't see a big advantage of HP > over Dell to warrant the extra cost, but I see nothing on Dell > about the Layer2/3 stuff ... but not sure what that gives either > ... If you're going to calculate a $ pr. port cost-benefit, then you have to make sure the rest of your setup is balanced accordingly (why spent time on $ pr. port if the nic in the rest of the setup is cheap) > > Price wise, both the HP and Dell versions look reasonable, and I > think the Dell is easier for me to get in Panama (I know there is a > local office for them there) ... There's a lot more to network boxes (router, bridge, switch et al.) than just price and capacity, e.g. management, (I)OS, firmware, support. best of luck. respectfully /per per@xterm.dk > > I've had one + for Dell ... does anyone have any caveats against > them?
