There are two device repository databases located in Operations Manager:
●
Operations Manager device inventory: To view, select Administration > Device Management > Device
Configuration > Modify/Delete.
●
The DCR inventory: To view, select Administration > Device Management > Device Configuration >
Device Credentials.
When you delete a device, it can be removed from either inventory. How Operations Manager is configured with
the DCR determines from which inventory a device is deleted. For Operations Manager/DCR configurations, see
the
“Synchronizing with the DCR” section
.
When a device is deleted, the inventory that it is removed from depends on the Operations Manager and DCR
configuration:
●
Standalone mode: The device is removed from both the Operations Manager and the DCR inventory.
●
Master mode: The device is removed from both the Operations Manager and the DCR inventory.
●
Slave mode: The device is removed only from the Operations Manager inventory.
After a device is in the DCR, you can select it to be monitored by Operations Manager. Operations Manager
performs inventory collection periodically, polling for relevant information from the devices.
Network Discovery Options
There are two network discovery options: Cisco Discovery Protocol-based discovery and ping-based discovery.
This section describes both options.
Cisco Discovery Protocol-Based Discovery
Operations Manager device discovery is based on Cisco Discovery Protocol, route table, and Address Resolution
Protocol (ARP) table using a seed device. Operations Manager uses Cisco Discovery Protocol neighbors, ARP
table, and route table entries to discover the network from the seed device.
Logical Cluster Discovery
Operations Manager device discovery is based on using Cisco Unified Communications Manager as a seed
device. Operations Manager uses logical registration relationships to discover the clusterwide devices from the
seed device.
When using Cisco Unified Communications Manager as the seed device, the following types of devices are
discovered:
●
Other Cisco Unified Communications Managers in the network
●
Cisco Unity
●
MGCP voice gateways
●
H.323 voice gateways
●
Gatekeepers
●
