<div>We have taken over a group of sites that have both the PCs and Cisco phones in VLAN 1. I know this is not a good idea. As part of our conversion one option being looked at is temporarily moving the data to a new VLAN 50 and leaving the phones in VLAN 1. Testing this I see the phone is now in both VLANs. The phone and PC seem to be working fine still I think that this may not be a valid config option and I am feeling very leery about this option. Opinions would be welcome. Here is what I got:</div>
