GNS3 to Real Network via USB.2.RJ45

Belkin adapters working just fine
-- trunking between switches and also when connected into routers

Cost: 2x $3.49

802.1q and VLANS in Linux are just ok.

sudo apt install vlan

modprobe 8021q

ip link enx00051b00c31f 10

ifconfig enx00051b00c31f.10

-- if you need also routing -- sudo nano /etc/sysctl.conf

ipv4.forwarding = 1

-- to make the interfaces for VLANs permanent edit /etc/network or use NetworkManager -- Add New and bridge a VLAN to physical interface directly

-- NOTE: not possible to connect it to IOU directly if running in VM, docker is solution or PHY int bridged to VM's interface

-- Docker also can be used as lightweight PC -- google for Docker as Ubuntu based Virtual machine
