Device Alias Databases

The device alias feature uses two databases to accept and implement device alias configurations.
•
•
If you modify the device alias configuration, you need to commit or discard the changes as the fabric
remains locked during this period.
Device alias database changes are validated with the applications. If any of the applications cannot
accept the device alias database changes, then those changes are rejected; this applies to device alias
database changes resulting from either a commit or merge operation.
