Editing VLAN (section)

==Membership==
VLAN membership can be established either statically or dynamically.

Static VLANs are also referred to as port-based VLANs. Static VLAN assignments are created by assigning ports to a VLAN.  As a device enters the network, the device automatically assumes the VLAN of the port. If the user changes ports and needs access to the same VLAN, the network administrator must manually make a port-to-VLAN assignment for the new connection.

Dynamic VLANs are created using software or by protocol.  With a [[VLAN Management Policy Server]] (VMPS), an administrator can assign switch ports to VLANs dynamically based on information such as the source MAC address of the device connected to the port or the username used to log onto that device.  As a device enters the network, the switch queries a database for the VLAN membership of the port that device is connected to. Protocol methods include [[Multiple VLAN Registration Protocol]] (MVRP) and the somewhat obsolete [[GARP VLAN Registration Protocol]] (GVRP).
