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.
