Cisco Catalyst 6000 Discovery
When discovering a Cisco Unified Communications Manager, Operations Manager discovers the trunk cards on a
Cisco Catalyst device as gateways. If the Cisco Catalyst device is not being monitored in Operations Manager, the
trunk cards will appear as grayed-out gateways in the service-level view until the Cisco Catalyst device is added
and monitored by Operations Manager. When the Cisco Catalyst device 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.
Troubleshooting Discovery Issues
If you can ping the device from the Operations Manager server and yet device discovery 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>
sm_snmpwalk.exe is located under C:\Program Files\CSCOpx\objects\smarts\bin folder on the Operations
Manager server. For detailed command syntax, use the following command:
sm_snmpwalk.exe --help
Device Import Options
Device import can be achieved through the options detailed in the following subsections.
Discovery-Based Import
To add devices automatically into Operations Manager, go to Administration > Device Management > Device
Configuration > DCR Device Selection. From the Device Selection page, select Automatic (the default device
selection setting for Operations Manager).
Synchronizing with the DCR
Operations Manager uses CiscoWorks Common Services as its application framework. The DCR, a function of
CiscoWorks Common Services, 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 with
compatible versions.
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.
To set up CiscoWorks LAN Management Solution (LMS) as DCR Master and Operations Manager as DCR Slave,
do the following:
Step 1. Make sure that the hostnames of both machines are DNS/hostname resolvable (check the entries in
c:\WINNT\system32\drivers\etc\hosts).
