in the fabric. On a successful commit, the configuration change is applied throughout the fabric and the

Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# ivr commit

Configured database—The database is manually configured by the user.
Active database—The database is currently enforced by the fabric.
Pending database—If you modify the configuration, you need to commit or discard the configured
database changes to the pending database. The fabric remains locked during this period. Changes to
the pending database are not reflected in the active database until you commit the changes to CFS.
No other user can make any configuration changes to this feature.
A copy of the configuration database becomes the pending database along with the first active
change.
