Change VLAN ID without taking VMs offline

Hello,

We require NIST 800-171 compliance and one of the changes we have to make is for the VM network to be on a different VLAN than the management network. When I tried to change the VLAN ID of the VM network, it took all the VMs offline until I changed it back. What am I doing wrong? I have attached our vSwitch topology.

Thank you

Hi,

The VLAN range is 1-4094
in the image you have assigned VLAN = 0 ...that is, you have disabled the VLANs

How did you configure the vlans on the physical Switch?

How does the physical switch ports' configuration look like?

You cannot just tag VLAN traffic on one side (e.g. virtual), and expect the other side (e.g. physical) to understand/accept the traffic.
