When the port WWN (pWWN) of a device must be specified to configure features (for example, zoning, DPVM, or port security) in a Cisco Nexus 5000 Series switch, you must assign the correct device name each time you configure these features. An inaccurate device name may cause unexpected results. You can circumvent this problem if you define a user-friendly name for a pWWN and use this name in all the configuration commands as required. These user-friendly names are referred to as device aliases.

•Device Alias Features
•Device Alias Requirements
•Zone Aliases Versus Device Aliases
Device Alias Features
Device aliases have the following features:
•The device alias information is independent of the VSAN configuration.
•The device alias configuration and distribution is independent of the zone server and the zone server database.
•You can import legacy zone alias configurations without losing data.
•The device alias application uses the Cisco Fabric Services (CFS) infrastructure to enable efficient database management and distribution. Device aliases use the coordinated distribution mode and the fabric-wide distribution scope (see Chapter 21, "Using Cisco Fabric Services").
•Basic and enhanced modes. See the "Device Alias Modes" section.
•Device aliases used to configure zones, IVR zones, or port security features are displayed automatically with their respective pWWNs in the showcommand output.
Device Alias Requirements
Device aliases have the following requirements:
•You can only assign device aliases to pWWNs.
•There must be a one-to-one relationship between the pWWN and the device alias that maps to it.
•A device alias name is restricted to 64 alphanumeric characters and may include one or more of the following characters:
–a to z and A to Z
–Device alias names must begin with an alphabetic character (a to z or A to Z).
