To configure VLANs inside a virtualized environment which device is used?

A virtual switch is used to configure VLANs inside a virtualization environment. It sits inside the hypervisor and connects all the virtual NICs of the virtual machines. VLAN IDs are assigned on the port groups or uplinks of this virtual switch, so frames from a VM can be tagged with the appropriate VLAN (802.1Q) and only reach the VMs or networks that belong to that same VLAN. This creates separate broadcast domains for the VMs without needing physical switches for each segment. The virtual switch is the central point for managing intra-host network segmentation. A physical switch handles VLANs in the broader data center network, and a router (or Layer 3 device) would be used if you need to route traffic between VLANs, but the VLAN configuration within the virtualized host itself is done on the virtual switch. A virtual NIC is simply the VM’s network interface and relies on the virtual switch for any VLAN tagging and separation.
