VLAN assignment in different usage scenarios

On the S5306, LS-S5352C-EI  EI, S5310EI, S5300HI, and S6300, if both the subnet VLAN and the MAC VLAN with a mask are configured, the MAC VLAN with a mask is first matched regardless of whether the vlan precedence command is used.

Access

Accepts an untagged frame and adds a tag with the default VLAN ID to the frame.

Accepts the tagged frame if the frame's VLAN ID matches the default VLAN ID.

Discards the tagged frame if the frame's VLAN ID differs from the default VLAN ID.

After the PVID tag is stripped, the frame is transmitted.

An access port can belong to only one VLAN. The access interface is directly connected to a computer.

Trunk

Adds a tag with the default VLAN ID to the untagged frame and then transmits it if the default VLAN ID is permitted by the port

Adds a tag with the default VLAN ID to the untagged frame and then discards it if the default VLAN ID is denied by the port.

Accepts the tagged frame if the frame's VLAN ID is permitted by the port.

Discards the tagged frame if the frame's VLAN ID is denied by the port.

If the frame's VLAN ID matches the default VLAN ID and the VLAN ID is permitted by the port, the device removes the tag and transmits the frame.

If the frame's VLAN ID differs from the default VLAN ID, but the VLAN ID is still permitted by the port, the switch will directly transmit the frame.

A trunk port allows packets of multiple VLANs to pass through. It usually connects network devices.

Hybrid

If the frame's VLAN ID is permitted by the port, the frame is transmitted. The port can be configured whether to transmit frames with tags.

A hybrid port allows packets of multiple VLANs to pass through. It can be used to connect network devices or network devices and user devices.

QinQ

QinQ ports are enabled with the IEEE 802.1QinQ protocol. A QinQ port can add double VLAN tags to a data frame, that is, a QinQ port can add a tag to a single-tagged frame. Therefore, a QinQ port supports a maximum of 4094 x 4094 VLAN tags, which meets the requirement on the number of VLANs. For details, see QinQ Overview.

he S5328C-SI  and S5300LI do not support VLAN aggregation.
