VLAN ID for a Hyper-V VM
VLAN ID (Virtual Local Area Network Identifier) is a number (1–4094) that tags network traffic so switches know which virtual network the packet belongs to.
Quick Explanation
VLANs allow you to separate a physical network into multiple logical networks.
Each VLAN has a unique VLAN ID.
Devices in the same VLAN can communicate with each other, even if connected to different switch ports.
Devices in different VLANs cannot communicate unless a router or L3 switch routes between them.
