There is no reason you can't use VLAN 1, but Cisco suggests avoiding it. I do not think this is your problem, but I can't understand what you are asking or what your problem is, so I can't know for sure. Here is a link to the vlan 1 stuff from

If you are not running Vlan's leaving it default is ok. If you want to vlan your traffic it is best to use a completely different vlan. All interfaces on the switch are configured as vlan1 by default. Maky your life alot simpler and set up a new vlan as the other user suggested and apply that vlan to the interfaces you want segmented.
