Zone Implementation

</h1>
<a name="wp1072988"> </a><p class="pBody">
All switches in the Cisco MDS 9000 Family automatically support the following basic zone features (no 
additional configuration is required):

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1072989"> </a><li class="pSmartList1">Zones are contained in a VSAN. 
</li>
<a name="wp1072990"> </a><li class="pSmartList1">Hard zoning cannot be disabled.
</li>
<a name="wp1072991"> </a><li class="pSmartList1">Name server queries are soft-zoned.
</li>
<a name="wp1072992"> </a><li class="pSmartList1">Only active zone sets are distributed.
</li>
<a name="wp1072993"> </a><li class="pSmartList1">Unzoned devices cannot access each other.
</li>
<a name="wp1072994"> </a><li class="pSmartList1">A zone or zone set with the same name can exist in each VSAN.
</li>
<a name="wp1072995"> </a><li class="pSmartList1">Each VSAN has a full database and an active database.
</li>
<a name="wp1072996"> </a><li class="pSmartList1">Active zone sets cannot be changed, without activating a full zone database.
</li>
<a name="wp1072997"> </a><li class="pSmartList1">Active zone sets are preserved across switch reboots.
</li>
<a name="wp1072998"> </a><li class="pSmartList1">Changes to the full database must be explicitly saved.
</li>
<a name="wp1072999"> </a><li class="pSmartList1">Zone reactivation (a zone set is active and you activate another zone set) does not disrupt existing 
traffic.
</li>
</ul></div>
<a name="wp1073000"> </a><p class="pBody">
If required, you can additionally configure the following zone features:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1073001"> </a><li class="pSmartList1">Propagate full zone sets to all switches on a per VSAN basis.
</li>
<a name="wp1073002"> </a><li class="pSmartList1">Change the default policy for unzoned members.
</li>
<a name="wp1073003"> </a><li class="pSmartList1">Interoperate with other vendors by configuring a VSAN in the interop mode. You can also configure 
one VSAN in the interop<b class="cBold"> </b>mode and another VSAN in the basic mode in the same switch without 
disrupting each other.
</li>
<a name="wp1073004"> </a><li class="pSmartList1">Bring E ports out of isolation.
</li>
