There is old article on this at Configuring ethernet port in trunk mode

On a trunk port there can be multiple tagged VLAN traffic. We can access traffic of a particular VLAN on a sub-interface. To create a sub-interface we need to create sub-interface configuration file using:

  1. Enable 8021q module using: 
    modprobe 8021q
    

    lsmod | grep 802
  2. Enable module on boot by creating '/etc/modules-load.d/01-8021q.conf' with: 
    8021q
  3. To access traffic of a particular VLAN on a sub-interface, create sub-interface configuration file '/etc/sysconffig/network-scripts/ifcfg-<interface-name>.<vlan-id>'.
    Example name /etc/sysconfig/network-scripts/ifcfg-eth0.101 if interface eth0 is in trunk mode with VLAN 101 traffic coming tagged. 
    VLAN=yes
    

    TYPE=Vlan
    

    PHYSDEV=eth0
    

    VLAN_ID=101
    

    REORDER_HDR=yes
    

    GVRP=no
    

    MVRP=no
    

    HWADDR=
    

    PROXY_METHOD=none
    

    BROWSER_ONLY=no
    

    BOOTPROTO=none
    

    IPADDR=10.100.1.11
    

    PREFIX=24
    

    GATEWAY=10.100.1.1
    

    DNS1=10.100.1.2
    

    DEFROUTE=yes
    

    IPV4_FAILURE_FATAL=no
    

    IPV6_DISABLED=yes
    

    IPV6INIT=no
    

    NAME=eth0.101
    

    DEVICE=eth0.101
    

    ONBOOT=yes
    and so on as per requirement.
  4. Restart network and see if sub-interface is up and running as expected 
    nmcli networking off; nmcli networking on


Note:

  • You can use 
    nmtui
    to configure appropriate interface and learn about the configuration parameters
