Configuring 10-Gbps FC Mode

</h1>
<a name="wp1159777"> </a><p class="pBody">
The 48-port 8-Gbps Advanced Fibre Channel module (DS-X9248-256K9) and the 32-port 8-Gbps 
Advanced Fibre Channel module (DS-X9232-256K9)can switch between two speed modes&#8212;the 1-, 2-, 
4-, 8-Gbps or 10-Gbps. By default, the modules are online in the 1-, 2-, 4-, and 8-Gbps modes when they 
are loaded for the first time. There are two ways to change the ports to the 10-Gbps speed mode: 

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1159778"> </a><li class="pSmartList1">Using the <b class="cBold">10G-speed mode </b>command, which is the recommended method.
</li>
<a name="wp1159779"> </a><li class="pSmartList1">Using the generic speed configuration <b class="cBold">switchport speed</b> command which has certain constraints. 
</li>
</ul></div>
<a name="wp1176812"> </a><p class="pBody">
The following conditions apply when the ports in the module can be configured to 10-Gbps speed mode:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1157691"> </a><li class="pSmartList1">The ports in the module can be configured to 10-Gbps speed only when the DS-13SLT-FAB3 module 
bandwidth is 256-G. Any other combination of fabric modules will not let the ports come up in 
10-Gbps. 
</li>
<a name="wp1157706"> </a><li class="pSmartList1">When in 10-Gbps mode, the ports in the module that are not 10-Gbps capable are disabled and will 
be in out-of-service state. 
</li>
<a name="wp1157721"> </a><li class="pSmartList1">The ports function only in full rate mode. They cannot be moved to shared rate mode. 
</li>
<a name="wp1157730"> </a><li class="pSmartList1">The ports cannot be configured in any other speed. 
</li>
<a name="wp1157739"> </a><li class="pSmartList1">Ports that are capable of 10-Gbps that are disabled or out-of-service cannot be put back in service 
using the <b class="cBold">no out-of-service</b> command. To put these ports back in service, all ports in the module 
first have to be moved to the out-of-service state. Then they can be brought back to the in service 
state. 
</li>
<a name="wp1179204"> </a><li class="pSmartList1">Local switching must be disabled, otherwise, ports cannot be configured in dedicated mode. 
</li>
</ul></div>
<a name="wp1157707"> </a><p class="pBody">
Only certain ports on the 48-port and 32-port 8-Gbps Advanced Fibre Channel modules are 10-Gbps 
capable. When running in 10-Gbps mode, the non-10-Gbps ports cannot be operational. They have to be 
either in shut state or out-of-service state.

Detailed Steps 
</h2>
<a name="wp1192433"> </a><p class="pBody">
To configure the interface mode using DCNM-SAN, follow these steps:

</p>
<div class="pSmartList1"><ol type="1" class="pSmartList1">
<a name="wp1192434"> </a><li class="pSmartList1">Expand<span style="font-weight: bold"> Switches&#160;&gt;&#160;FC Interfaces&#160;&gt;</span>&#160;<span style="font-weight: bold">Physical</span>. 
</li>
<a name="wp1192435"> </a><p class="pListBodyLevel1">
You see the interface configuration in the Information pane.

</p>
<a name="wp1192436"> </a><li class="pSmartList1">Click the <span style="font-weight: bold">General</span> tab. 
</li>
<a name="wp1192437"> </a><li class="pSmartList1">Click <span style="font-weight: bold">Mode Admin</span>. Set the desired interface mode from the Admin drop-down menu. 
</li>
<a name="wp1192438"> </a><li class="pSmartList1">(Optional) Set other configuration parameters using the other tabs.
</li>
<a name="wp1192439"> </a><li class="pSmartList1">Click <span style="font-weight: bold">Apply Changes </span>icon.
