In case anyone finds this via google, I have figured out I can (via the web gui) upload the config file to a server, make the changes to the VLAN's, then Download the config to the switch (as startup-config).  I can then run "reload" and it will re-read the config.  it did make my switch unresponsive for a min or so while it was doing a warm reset.
I need to change our 'main' vlan from 10 to 30 (to better match up with another office). I have six PowerConnect  7024 switches in a virtual chassis, and all but a couple ports need to change. (a few servers on VLAN 20) My thought (since there are not yet any production systems on there) is to set the whole Interface Range (gi1/0/1-gi6/0/24) to "switchport access vlan 30" and then manually switch the few ports that should be on VLAN 20 manually. however, the switches IP address is set on Interface VLAN 10, won't that disconnect my SSH session?   Is there a way (like with the j-class switches) to type the changes in, then type commit?   Thanks
is there a "commit" function for the configuration? (like the j-class)
