Create the VLAN interface. For example, to create a VLAN interface named vlan10 that uses enp1s0 as its parent interface and that tags packets with VLAN ID 10, enter: # nmcli connection add type vlan con-name vlan10 ifname vlan10 vlan.parent enp1s0 vlan.id 10. Note that the VLAN must be within the range from 0 to 4094 .

An Ethernet packet normally has one VLAN tag, identifying to which VLAN it belongs to. Such a tag can be set, changed or removed in certain VLAN aware devices. A packet routed into a sub-interface gets a VLAN tag with the VLAN ID of the sub-interface. The rules at bridge ports are more complicated and device and/or vendor dependent.
There are two types of packets on a VLAN, these are tagged and untagged packets. The untagged packet is a regular packet and looks just like a packet that ...

Similarly mapped the VLAN 300 to NIC enp0s3
A VLAN is a logical network within a physical network. The VLAN interface tags packets with the VLAN ID as they pass through the interface, and removes tags of returning packets. You create a VLAN interface on top of another interface, such as an Ethernet, bond, team, or bridge device. This interface is called the parent interface.
VLAN interfaces created using ip commands at the command prompt will be lost if the system is shutdown or restarted. To configure VLAN interfaces to be persistent after a system restart, use ifcfg files. See Section 10.4.1, “Setting Up 802.1Q VLAN Tagging Using ifcfg Files”
