When the port WWN (pWWN) 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 correct device name each 
time you configure these features. An incorrect device name can cause unexpected results. You can avoid 
this problem if you define a user-friendly name for a port WWN and use this name in all of the 
configuration commands as required. These user-friendly names are referred to as <em class="cEmphasis">device</em> <em class="cEmphasis">aliases </em>in this 
chapter.
