You can configure the port mode and VLAN members for a port to determine VLANs that are allowed to pass
through the port and whether packets to be forwarded by the port carry the tag field.

Port Modes Description
Port mode
Function
Access port
One access port can belong to only one VLAN and allow only frames from this VLAN to pass
through. This VLAN is called an access VLAN.
Access VLAN has attributes of both Native VLAN and Permitted VLAN
The frames sent from the Access port do not carry tags. When the access port receives an
untagged frame from a peer device, the local device determines that the frame comes from the
Access VLAN and adds the access VLAN ID to the frame.
Trunk port
One trunk port supports one native VLAN and several allowed VLANs. Native VLAN frames
forwarded by a trunk port do not carry tags while allowed VLAN frames forwarded by the trunk
port carry tags.
A trunk port belongs to all VLANs of the device by default, and can forward frames of all
VLANs. You can set the allowed VLAN range to limit VLAN frames that can be forwarded.
Note that the trunk ports on both ends of the link must be configured with the same Native
VLAN.
Hybrid port
A hybrid port supports one native VLAN and several allowed VLANs. The allowed VLANs are
divided into Tag VLAN and Untag VLAN. The frames forwarded by the hybrid port from a Tag
VLAN carry tags, and the frames forwarded by the hybrid port from an Untag VLAN do not
carry tags. The frames forwarded by the hybrid port from Native VLAN must not carry tags,
therefore Native VLAN can only belong to Untag VLAN List.
Note
Whether the hybrid mode function is supported depends on the product version.
