Dynamic VSAN Configuration
Port VSAN membership on the switch is assigned on a port-by-port basis. By default each port belongs
to the default VSAN.
As of Cisco MDS SAN-OS Release 2.x, you can dynamically assign VSAN membership to ports by
assigning VSANs based on the device WWN. This method is referred to as the Dynamic Port VSAN
Membership (DPVM) feature. DPVM offers flexibility and eliminates the need to reconfigure the VSAN
to maintain fabric topology when a host or storage device connection is moved between two Cisco MDS
switches. It retains the configured VSAN regardless of where a device is connected or moved.
To assign VSANs statically, see Chapter 13, “VSAN Configuration.”

About DPVM
DPVM configurations are based on the port world wide name (pWWN). The pWWN identifies the host
or device.A DPVM database contains mapping information for each device pWWN assignment and the
corresponding VSAN. Cisco MDS SAN-OS checks the database during a device FLOGI and obtains the
required VSAN details.
