For 802.1Q VLAN, every port could be tag port or untag port.
Tag port will always send tagged packets and is used for switch-to-switch
cascading. It is a VLAN trunk connection because there could be more than one
VLAN working through it. And its role is a “Trunk” for 802.1Q VLAN groups
operation between switches.
Untag port will always send untagged packets and is used for switch to users
connection. And its role is a “Access” connection for users.
You can define ports as “Trunk” or “Access” according to their connection
devices.
If a port is defined as “Hybrid”, it is a tag port basically. But it will act as an
untag port for packets working in VLAN defined in “Untag VID”. So, it is called a
hybrid port.
For example, set Port 5 as “Hybrid” and its Untag VID as 10. Port 5 will act as a
tag port for all packets except packets for VLAN 10. Port 5 will act as an untag
port for packets working for VLAN 10.
