About Device Aliases

When the port WWN of a device must be specified to configure different features (zoning, QoS, port
security) in a Cisco MDS 9000 Family switch, you must assign the right 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 port WWN and use this name in all the
configuration commands as required. These user friendly names are referred to as device aliases in this
chapter.
All switches in the Cisco MDS 9000 Family support Distributed Device Alias Services (device alias) on
a per VSAN basis and on a fabric-wide basis. Device alias distribution allows you to move host bus
adapters (HBAs) between VSANs without manually reentering alias names.
