<a name="wp345071"> </a><p class="pBody">
To set your preferences for the behavior of the Cisco DCNM-SAN, choose <b class="cBold">File &gt; Preferences</b> from the 
Cisco DCNM-SAN menu bar. You see the Preferences dialog box with the following tabs for setting 
different components of the application:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp345072"> </a><li class="pSmartList1">General

<a name="wp345074"> </a><li class="pSmartList1">Map
</li>
</ul></div>
<a name="wp345076"> </a><p class="pBody">
The default General preferences for Cisco DCNM-SAN are as follows:

</p>

logical name. The default setting for this value is Logical Name.
</li>
<a name="wp345080"> </a><li class="pSmartList1"><b style="font-weight: normal" class="cBold">Show WorldWideName (WWN) Vendor</b>&#8212;Displays the world wide name vendor name in any table 
or listing displayed by Cisco DCNM-SAN. Check the <span style="font-weight: bold">Prepend Name</span> check box to display the name 
in front of the IP address of the switch. Check the <span style="font-weight: bold">Replacing Vendor Bytes</span> check box to display 
the name instead of the IP address. The default is the Prepend Name option.
</li>
<a name="wp345082"> </a><li class="pSmartList1"><b style="font-weight: normal" class="cBold">Show End Device Using</b>&#8212;Displays end devices in the Fabric pane using alias or pWWN alias. The

<a name="wp345088"> </a><li class="pSmartList1"><b style="font-weight: normal" class="cBold">Telnet Path</b>&#8212;Displays the path for the telnet.exe file on your system. The default is <b style="font-weight: normal" class="cBold">telnet.exe</b>, but 
you need to browse for the correct location.
</li>
<a name="wp345089"> </a><p class="pBodyAutonumRel">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> If you browse for a path or enter a path and you have a space in the pathname (for example, 
<b style="font-weight: normal" class="cBold">c:\program files\telnet.exe)</b>, then the path will not work. To get the path to work, you must 
manually place quotes around it (for example, <b style="font-weight: normal" class="cBold">&quot;c:\program files\telnet.exe&quot;</b>).

that you want to see. (This feature is useful for large fabrics that cannot be displayed entirely within 
the Fabric pane.) Bring up the overview window by clicking the <span style="font-weight: bold">Show/Hide Overview Window</span> 
button. It overlays the fabric window and remains there until you click the <span style="font-weight: bold">Show/Hide Overview 
Window</span> button again. If you enable this preference, you can detach the overview window and move
