Device Alias Databases; Creating Device Aliases - Cisco Nexus 5000 Series Configuration Manual

Distributing Device Alias Services
Zone-Based Aliases
Configuration is contained within the zone server
database and is not available to other features.

Device Alias Databases

The device alias feature uses two databases to accept and implement device alias configurations.
• Effective database—The database currently used by the fabric.
• Pending database—Your subsequent device alias configuration changes are stored in the pending database.
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.

Creating Device Aliases

You can create a device alias in the pending database.
