About Autolearned Entries

</h1>
<a name="wp1073256"> </a><p class="pBody">
The DPVM database can be configured to automatically learn (autolearn) about new devices within each 
VSAN. The autolearn feature can be enabled or disabled at any time. Learned entries are created by 
populating device pWWNs and VSANs in the active DPVM database. The active DPVM database should 
already be available to enable autolearn.

</p>
<a name="wp1073257"> </a><p class="pBody">
You can delete any learned entry from the active DPVM database when you enable autolearn. These 
entries only become permanent in the active DPVM database when you disable autolearn.

</p>
<a name="wp1073260"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> Autolearning is only supported for devices connected to F ports. Devices connected to FL ports are not 
entered into the DPVM database because DPVM is not supported on FL ports.

</p>
<a name="wp1073261"> </a><p class="pBody">
The following conditions apply to learned entries:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1073262"> </a><li class="pSmartList1">If a device logs out while autolearn is enabled, that entry is automatically deleted from the active 
DPVM database.
</li>
<a name="wp1073263"> </a><li class="pSmartList1">If the same device logs multiple times into the switch through different ports, then the VSAN 
corresponding to last login is remembered.
</li>
<a name="wp1073264"> </a><li class="pSmartList1">Learned entries do not override previously configured and activated entries. 
</li>
<a name="wp1073265"> </a><li class="pSmartList1">Learning is a two-part process&#8212;Enabling autolearning followed by disabling autolearning. When 
the <b class="cBold">auto-learn</b> option is enabled, the following applies:
</li>
<div class="pSmartList2"><ul class="pSmartList2">
<a name="wp1073266"> </a><li class="pSmartList2">Learning currently logged-in devices&#8212;Occurs from the time learning is enabled. </li>
<a name="wp1073267"> </a><li class="pSmartList2">Learning new device logins&#8212; Occurs as and when new devices log in to the switch.</li>
</ul></div>
</ul></div>
