fabric-wide basis.

Information About Device Aliases

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 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

• The device alias application uses the Cisco Fabric Services (CFS) infrastructure to enable efficient
• Basic and enhanced modes.
• Device aliases used to configure zones, IVR zones, or port security features are displayed automatically
