Can you share information on how to create two different subnets to be on the same vlan? This is only temporary to ensure that the cut-over to the network is validated. I know it is not recommended but the PACS/RIS people want to move over without any downtime.

You can have multiple subnets on the same vlan, just assign the endhosts with the ip addresses desired.

For example

192.168.1.0/24  host will be in this subnet
192.168.2.0/24 hosts will be in this subnet.

The ports can all be configured with the same vlan. Only the hosts on the same subnet will be able to talk to one another.

If you need them to talk to one another, and you have an existing l3 interface to route, just add the second subnet as a secondary ip address.

You can do it this way:

interface Vlan(number)
ip address 10.10.10.1 255.255.255.0
ip address 20.20.20.1 255.255.255.0 secondary
ip address 30.30.30.1 255.255.255.0 secondary
