the configuration database.
Saving the configuration only saves the activated
entries. Learned entries are not saved.
Once activated, the configuration database can be
modified without any effect on the active
database.
Once activated, all devices that have already
logged into the VSAN are also learned and added
to the active database.
You can overwrite the configuration database with
the active database.
You can overwrite the active database with the
configured database by activating the port
security database. Forcing an activation may
violate the entries already configured in the active
database.
