4.3.2 MAC VLAN
Overview
MAC VLAN technology is the way to classify VLANs according to the MAC addresses of Hosts. MAC VLAN
only takes effect on ingress untagged data. When the port receives an untag packet, the device, with the matching
key words of the packets’ source MAC address, will search MAC VLAN entries to obtain the terminal’s binding
VLAN. In this way, packets of the designated terminal will be forwarded in the designated VLAN. Thus, the user
terminal and VLAN will be bound accurately and flexibly.
Benefits of MAC VLAN
A MAC address corresponds to a single VLAN ID. For the device in a MAC VLAN, if its MAC address is bound
to VLAN, the device can be connected to another member port in this VLAN and still takes its member role effect
without changing the configuration of VLAN members.
Implementation of MAC VLAN
The packet in MAC VLAN is processed in the following way:
1. When receiving an untagged packet, the switch will check whether the corresponding MAC VLAN has been
created. If the corresponding MAC VLAN has been created, the switch will add a corresponding MAC VLAN tag
to it. If no MAC 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 based 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 MAC address of a Host is classified into 802.1Q VLAN, please set its connected port of switch to be a
member of this 802.1Q VLAN so as to ensure the packets forwarded normally.
