DPVM Database Distribution
If fabric distribution is enabled, all changes to the configuration database are stored in the DPVM
pending database. These changes include the following tasks:
•
Adding, deleting, or modifying database entries.
•
Activating, deactivating, or deleting the configuration database.
•
Enabling or disabling autolearning.
These changes are distributed to all switches in a fabric when you commit the changes. You can also
discard (abort) the changes at this point.
Tip
You can view the contents of the DPVM pending database by issuing the
show dpvm pending
command.
Disabling DPVM Database Distribution
To disable DPVM database distribution to the neighboring switches, follow these steps:
About Locking the Fabric
The first action that modifies the existing configuration creates the DPVM pending database and locks
the feature in the fabric. Once you lock the fabric, the following conditions apply:
•
No other user can make any configuration changes to this feature.
•
A copy of the configuration database becomes the DPVM pending database. Modifications from this
point on are made to the DPVM pending database. The DPVM pending database remains in effect
until you commit the modifications to the DPVM pending database or discard (abort) the changes
to the DPVM pending database.
