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.
The following example displays a failed device alias status:
switch# show device-alias status
Fabric Distribution: Disabled
Database:- Device Aliases 25
Status of the last CFS operation issued from this switch:
==========================================================
