Long time no speak!
I've got a 3750 that has some vlans configured on it. We're moving a complete location to our corporate office, and I'm wanting to keep them the same way that they are over there. When they come in, they'll be getting rid of a router. I was going to create a vlan for their existing subnet and give them a L2 switch. I was then going to create the vlans on the L2 switch and change their native vlan to be the vlan that I created for their subnet. On the 3750 for that one port, I would change the native vlan to the vlan for their subnet. The native vlans for all of the other ports on the 3750 would be vlan 1. I think it should work in concept.
This will work absolutely fine. The native vlan is relevant to the specific trunk port so you can have all your other trunks with native vlan 1 but the port connecting to the dell switch with a native vlan of 95.
Edit - this is assuming the Dell switch supports 802.1q trunks.
By the way, how have you been. Haven't seen you on these forums for a while.
