Information About Device Aliases

Cisco SAN switches support Distributed Device Alias Services (device aliases) on a fabric-wide basis.
When the port WWN (pWWN) of a device must be specified to configure features (for example, zoning,
DPVM, or port security) in a Cisco SAN 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
• You can import legacy zone alias configurations without losing data.
• The device alias application uses the Cisco Fabric Services (CFS) infrastructure to enable efficient
• Basic and enhanced modes.
