Configure a MAC Address-Based VLAN
MAC address-based VLANs, also called MAC VLANs, are classified according to the source MAC addresses of the packets. After a MAC VLAN is configured, if the port receives an Untag packet and the source MAC address of the packet matches a MAC VLAN entry, the system adds a VLAN tag for the packet, in which the VLAN ID matches the VLAN ID in the MAC VLAN entry.
After the physical location of the user is changed, if the MAC address of the user is not changed, the VLAN to which the user port belongs need not be re-configured.
