IEEE 802.1Q describes concepts called the shared VLAN (SVL) and independent VLAN (IVL). These define how bridges store MAC addresses in their bridging tables. SVL constrains a MAC address to only one VLAN.

SVL-based devices build a giant bridge table, but allow a MAC address to appear only once in the table, gardless of how many VLANs exist.
