Level View until the Cisco Catalyst is added and monitored by Operations Manager.  
When the Cisco Catalyst is added to Operations Manager, the gateways associated with 
the trunk cards will be replaced with a single Cisco Catalyst icon in the Service Level 
View. 
5.3.1.6 Troubleshooting Discovery Issues 
If you can ping the device from the Operations Manager server and device discovery still 
fails, it is typically due to an SNMP problem such as a community string mismatch. Try 
to ping SNMP from the Operations Manager server.   
From the command prompt, enter the following command: 
sm_snmpwalk.exe -w -c <snmp community string> <device IP> 
 
5.3.2 Device Import Options 
5.3.2.1 Discovery-Based Import 
To add devices automatically into Operations Manager, go to Devices > Device 
Management
. From the Device Management: Summary page, click the Configure 
button next to Device Selection. From the Device Selection page, select Automatic (the 
default device selection setting for Operations Manager). 
 
5.3.2.2 Synchronizing with the DCR 
Operations Manager uses CiscoWorks Common Services 3.0 as its application 
framework. The Device and Credentials Repository (DCR), a function of CiscoWorks 
Common Services 3.0, is a common repository of devices, their attributes, and their 
credentials required to manage devices in a management domain. The DCR lets you share 
device information among various network management applications.  
For example, the device credentials can be shared between: 
  Multiple instances of Operations Manager  
  Instances of Operations Manager and any CiscoWorks applications running on 
Common Services version 3.0 or later. 
To share the device credentials, the DCR server can run in Master mode, Slave mode, or 
Standalone mode. You can change mode through the user interface or the DCR 
command-line interface.
