Protocol Vlan - TP-Link TL-SL5428E User Manual

The packet in Protocol VLAN is processed in the following way:
1. When receiving an untagged packet, the switch matches the packet with the current Protocol
VLAN. If the packet is matched, the switch will add a corresponding Protocol VLAN tag to it. If
no Protocol VLAN is matched, the switch will add a tag to the packet according to the PVID of
the received port. Thus, the packet is assigned automatically to the corresponding VLAN for
transmission.
2. When receiving tagged packet, the switch will process it basing on the 802.1Q VLAN. If the
received port is the member of the VLAN to which the tagged packet belongs, the packet will
be forwarded normally. Otherwise, the packet will be discarded.
3. If the Protocol VLAN is created, please set its enabled port to be the member of
corresponding 802.1Q VLAN so as to ensure the packets forwarded normally.
