Physical setup:
A Microsoft windows server with two NICs connected to a Network switch. There is a requirement to extend multiple VLANs to the server.Steps:

Technically, All the packets passing through trunk ports must have an VlanID in the ethernet packet. the receiving switch decides where to forward the packet based on the VlanID tag. If any packet arrives without VlanID, it is considered as packet belonging to the VLAN marked as "Native VLAN". In cisco switches, "Vlan 1" is the default "Native VLAN".Cisco Switch commands:
