Call Home Database Merger Guidelines
</h2>
<a name="wp1136614"> </a><p class="pBody">
When merging two Call Home databases, follow these guidelines:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1100580"> </a><li class="pSmartList1">Be aware that the merged database contains the following information:
</li>
<div class="pSmartList2"><ul class="pSmartList2">
<a name="wp1100581"> </a><li class="pSmartList2">A superset of all the destination profiles from the dominant and subordinate switches that take part in the merge protocol.</li>
<a name="wp1100582"> </a><li class="pSmartList2">The e-mail addresses and alert groups for the destination profiles.</li>
<a name="wp1100583"> </a><li class="pSmartList2">Other configuration information (for example, message throttling, periodic inventory) from the switch that existed in the dominant switch before the merge. </li>
</ul></div>
<a name="wp1100584"> </a><li class="pSmartList1">Verify that two destination profiles do not have the same name (even if they have different 
configuration information) on the subordinate and dominant switches. If they do contain the same 
name, the merge operation will fail. You must then modify or delete the conflicting destination 
profile on the required switch.
</li>
</ul></div>

See the <a href="cfs15.html">&quot;CFS Merge Support&quot; topic</a> for detailed concepts.

Call Home Configuration Guidelines
</h2>
<a name="wp1192041"> </a><p class="pBody">
When configuring Call Home, follow these guidelines:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1136320"> </a><li class="pSmartList1">An e-mail server and at least one destination profile (predefined or user-defined) must be 
configured. The destination profile(s) used depends on whether the receiving entity is a pager, 
e-mail, or automated service such as Cisco Smart Call Home.
</li>
<a name="wp1136321"> </a><li class="pSmartList1">Switches can forward events (SNMP traps/informs) up to 10 destinations.
</li>
<a name="wp1136323"> </a><li class="pSmartList1">The contact name (SNMP server contact), phone, and street address information must be configured 
before Call Home is enabled. This configuration is required to determine the origin of messages 
received.
</li>
<a name="wp1136324"> </a><li class="pSmartList1">The Cisco MDS 9000 Family switch and the Cisco Nexus 5000 Series switch must have IP 
connectivity to an e-mail server.
</li>
<a name="wp1136325"> </a><li class="pSmartList1">If Cisco Smart Call Home is used, an active service contract must cover the device being configured.
</li>
