I am replacing a Linksys switch with a 3750 on my backbone network. I did little to no configuration on that switch. Now that I am replacing it I have question regarding VLAN 1 on the new switch. It will be a flat L2 switch on backbone network which connects my FW's to my core 3750.
Is it best practice to move all the ports out of VLAN 1 into another vlan? IE: say my backbone is 10.35.66.0/24, could I just create a VLAN local to that switch (say VLAN 660) and move all the ports in to that vlan? If I add another switch to the backbone can I create the same vlan local to that switch and again move all the ports off VLAN1 (IE VLAN 660 on switch 2)?
The routing for that network is done via the physical interface on the L3 3750 so that vlan wouldn't exist on the L3 3750.
Can someone help me wrap my head around it?
Here is a crude diagram, the switch in question is the L2 3750.
