DPVM Database Not Distributed
Symptom DPVM databases are not distributed.
DPVM Autolearn Not Working
The DPVM autolearn feature allows you to automatically populate the DPVM configuration database
with all devices currently in the fabric. This feature is best used when you first turn on DPVM in a stable
fabric. Once the devices are learned, you disable autolearning to populate the configuration database
with these autolearned entries.
When you add a new device, it is a best practice to manually add that device to the DPVM configuration
database. If you turn on autolearning for a new device, you may add other devices that you did not intend
to add.
Symptom DPVM autolearn does not work or is not getting enabled.
Note When DPVM distribution is enabled, you must do an explicit commit for DPVM activate and autolearn
to take effect.

distribution is not enabled. Set the Global field to enable
in Fabric Manager and then click Apply Changes or use

Active Database tab in Fabric Manager or use the show
dpvm database CLI command to verify that DPVM is not
enabled. Select the Actions tab and set the Action field to
activate in Fabric Manager and then click Apply Changes
or use the dpvm activate and dpvm commit CLI
commands to create the DPVM active database.
