Sorry, but the PowerConnect line does not have a feature like this. You would need to look at each ports configuration and see what part of that you wanted to keep or delete, or change. And then make those changes.  You can reset the whole switch by running the following commands. To reset a switch to factory defaults use the following commands:  • delete startup-config or simply del start.  • reload But this may be further than you want to go. Did you have a specific setting on the ports you were needing to change? Thanks.
I'm extremely new to Dell PowerConnect so bare with me. I work for a large education organisation and for the last 15 year we have only bought Cisco.  I'm loving the PowerConnect 8024f and 5524p, very happy with both of them, I'm just lost on how to quickly clear a port of all config and make it stock/blank again.  In Cisco IOS land I was very used to running (at config) default int gig 1/0/12, or even default int range gig 1/0/1-12, but I'm struggling to find the equal for the PowerConnects.  I'm running firmware 4.2.2.3 on the 8024f and 4.1.0.1 5524p. Thanks in advance.   If I've missed a previous post that goes over this my apologies, I'm new to the forum as well.
