AAA Server Distribution

</h1>
<a name="wp1079006"> </a><p class="pBody">
Configuration for RADIUS and TACACS+ AAA on an MDS switch can be distributed using the Cisco 
Fabric Services (CFS). The distribution is disabled by default (see the <span style="font-style: italic">System Management 
Configuration Guide, Cisco DCNM for SAN</span>). 

</p>
<a name="wp1079007"> </a><p class="pBody">
After enabling the distribution, the first server or global configuration starts an implicit session. All 
server configuration commands entered thereafter are stored in a temporary database and applied to all 
switches in the fabric (including the originating one) when you explicitly commit the database. The 
various server and global parameters are distributed, except the server and global keys. These keys are 
unique secrets to a switch and should not be shared with other switches.

</p>
<a name="wp1079008"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> Server group configurations are not distributed.

</p>
<a name="wp1079246"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> For an MDS switch to participate in AAA server configuration distribution, it must be running Cisco 
MDS SAN-OS Release 2.0(1b) or later, or Cisco NX-OS Release 4.1(1).
