DPVM does not cause any changes to device addressing. DPVM only pertains to the VSAN membership
Note
of the device, ensuring that the host gets same VSAN membership on any port on the switch. For
example, if a port on the switch has a hardware failure, you can move the host connection to another port
on the switch and not need to update the VSAN membership manually.
DPVM is not supported on FL ports. DPVM is supported only on F ports.

corresponding to the dynamic port is deleted or suspended, the port is shut down.

Enabling DPVM

To begin configuring DPVM, you must explicitly enable DPVM on the required switches in the fabric.
By default, this feature is disabled in all switches in the Cisco MDS 9000 Family.
The configuration and verification commands for DPVM are only available when DPVM is enabled on
a switch. When you disable this feature, all related configurations are automatically discarded.

The interface through which the dynamic device connects to the Cisco MDS 9000 Family switch
must be configured as an F port.
The static port VSAN of the F port should be valid (not isolated, not suspended, and in existence).
The dynamic VSAN configured for the device in the DPVM database should be valid (not isolated,
not suspended, and in existence).
