About Device Alias Distribution

By default, device alias distribution is enabled. The device alias feature uses CFS to distribute the modifications
to all switches in a fabric.
If device alias distribution is disabled, database changes are not distributed to the switches in the fabric. The
same changes would have to be performed manually on all switches in the fabric to keep the device alias
database up-to-date. Database changes immediately take effect, so there would not be any pending database
and commit or abort operations either. If you have not committed the changes and you disable distribution,
then a commit task will fail.
