Hi. I currently have 4 sets of stacked 3750's (two switches in each stack) and due to a move in our datacenter, they are now all physically in the same place. I'd like to combine them all into a single 8 switch stack. From the documentation I've been reading, if I take an existing switch as the master and start adding more switches into the stack, the master will overwrite their existing config (port speeds/duplex, VLAN assignments, etc.) If this the case? or will the master detect that "hey, this new switch is already configured, I'll just assign it new port numbers and leave the VLANs and port speed/ duplex settings as is" and just assign them new port #'s and leave everything else alone. We only have a few VLAN's in use, and most ports are at gig/full duplex, so I could just manually re-configure the few ports that are not, but the less downtime the better.
Thanks so much! Josh
