Default FICON Port Numbering Scheme

</h1>
<a name="wp1072968"> </a><p class="pBody">
Default FICON port numbers are assigned by the Cisco MDS NX-OS software based on the module and 
the slot in the chassis. The first port in a switch always starts with a zero (0).

</p>
<a name="wp1153379"> </a><p class="pFigureCaption">
Figure&#160;25-1	Default FICON Port Number in Numbering on the Cisco MDS 9000 Family Switch

</p><div align="left"><img src="images/105217.jpg" height="308" width="576" id="wp1153381" border="0" hspace="0" vspace="0"/></div><p class="pBodyRelative">
</p>
<a name="wp1072978"> </a><p class="pBody">
The default FICON port number is assigned based on the front panel location of the port and is specific 
to the slot in which the module resides. Thirty-two (32) port numbers are assigned to each slot on all 
Cisco MDS 9000 Family switches except for the Cisco MDS 9513 Director, which has 16 port numbers 
assigned for each slot. These default numbers are assigned regardless of the module’s physical presence 
in the chassis, the port status (up or down), or the number of ports on the module (4, 12, 16, 24, or 48). 
If a module has fewer ports than the number of port numbers assigned to the slot, then the excess port 
numbers are unused. If a module has more ports than the number of port numbers assigned to the slot, 
the excess ports cannot be used for FICON traffic unless you manually assign the port numbers.

</p>
<a name="wp1072979"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> Follow the steps in <a href="ficon37.html">&quot;Assigning FICON Port Numbers to Slots&quot; topic</a> to make use of excess ports by 
manually assigning more port numbers to the slots. Before doing this, however, we recommend that you 
review the default port number assignments for Cisco MDS 9000 switches shown in <a href="ficon35.html#wp1079802">Table&#160;25-3</a> 
<a href="ficon13.html#wp1073009">Table&#160;25-1</a>, and that you read the following sections to gain a complete understanding of FICON port 
numbering: <a href="ficon16.html">&quot;About the Reserved FICON Port Numbering Scheme&quot; topic</a>, <a href="ficon32.html">&quot;FICON Port Numbering 
Guidelines&quot; topic</a>, and <a href="ficon37.html">&quot;Assigning FICON Port Numbers to Slots&quot; topic</a>.

<a name="wp1072998"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> Only Fibre Channel, PortChannel, and FCIP ports are mapped to FICON port numbers. Other types of 
interfaces do not have a corresponding port number.
