Disabling CFS Distribution on a Switch

</h1>
<a name="wp1430858"> </a><p class="pBody">
By default, CFS distribution is enabled. Applications can distribute data and configuration information 
to all CFS-capable switches in the fabric where the applications exist. This is the normal mode of 
operation.

</p>
<a name="wp1430859"> </a><p class="pBody">
You can globally disable CFS on a switch to isolate the applications using CFS from fabric-wide 
distributions while maintaining physical connectivity. 

</p>

Restrictions
</h2>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1430922"> </a><li class="pSmartList1">When CFS is globally disabled on a switch, CFS operations are restricted to the switch and all CFS 
commands continue to function as if the switch were physically isolated.
