• VLAN function. It specifies the port behaviour when processing the tag 802.1q,
where the options are edge, trunk, untag, native, QinQ Core or QinQ Access.
Edge: The 802.1 frames will be transmitted with the same 802.1q configuration they
had when they are received by the switch, that is, if the received frame included a
tag, it will be transmitted with a tag, and if the received frame did not include a tag,
it will be transmitted without a tag.
In PVLAN operating, the interfaces with Edge function operate always untagged
(without tag).
Trunk: All the frames will in all cases be transmitted with a tag. It is the specific
mode for connection with other switching devices, so as preserve the VLAN
information between switches.
Tag: The 802.1 frames will be transmitted with a tag, regardless of the fact that they
have a tag or not when they are received by the equipment.
Untag: The 802.1 frames will be transmitted without a tag, regardless of the fact
that they have a tag or not when they are received by the equipment.
Native: The native mode is equivalent to Trunk mode, except that the frames
belonging to the VLAN that matches the configured VID are transmitted without tag.
This mode of operation is equivalent to Native VLAN of Cisco, with the consideration
that the native VLAN is port-to-port defined by means of the VID parameter.
