I think that requires incoming traffic to have an 802.1q tag of vlan 30 to work.. > However, I was unable to find an IOS way, does one exist? switchport voice vlan 30 But that still requires incoming traffic to have a vlan 30 tag. > I'm attempting move machines from one subnet to another, and rather > than do this one at a time, 2 vlans would be ideal. Why not one vlan & two subnets? If you're starting out with, say interface vlan 20 ip address 192.168.20.1 255.255.255.0 ip helper-address 192.168.100.10 change it to interface vlan 20 ip address 192.168.30.1 255.255.255.0 ip address 192.168.20.1 255.255.255.0 secondary ip helper-address 192.168.100.10 Fix the DHCP server to give out 192.168.30.xxx addresses, reconfigure the machines with static addresses to use the new subnet & when they're all moved over + all the old leases have expired, remove the secondary address.
