About the Default VSAN

</h1>
<a name="wp1073726"> </a><p class="pBody">
The factory settings for switches in the Cisco MDS 9000 Family have only the default VSAN 1 enabled. 
We recommend that you do not use VSAN 1 as your production environment VSAN. If no VSANs are 
configured, all devices in the fabric are considered part of the default VSAN. By default, all ports are 
assigned to the default VSAN. 

</p>
<a name="wp1073727"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> VSAN 1 cannot be deleted, but it can be suspended.

</p>
<a name="wp1073728"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> Up to 256 VSANs can be configured in a switch. Of these, one is a default VSAN (VSAN 1), and another 
is an isolated VSAN (VSAN 4094). User-specified VSAN IDs range from 2 to 4093.
