CDM Mapping for Network Device

This topic provides information on mapping for network devices.

Network Device nodes in the Discovery model are mapped to the Common Data Model as shown in this automatically-generated diagram:

This diagram illustrates how the Network Device nodes in the Discovery model are mapped to the Common Data Model.

The CIs created are described in this topic.

Load balancers are mapped as Network Devices. The mapping is described in CDM Mapping for Load Balancer nodes.

Data models

CMDB version differences

The default mapping works with CMDB versions 7.5, 7.6, and 7.6.03 and later. The data model in each is slightly different.

  • BMC_Impact relationships are not normally created with CMDB 7.6.03 and later, since the CMDB automatically maintains them itself. See the information about impact relationships for more details.
  • A number of attributes are not present in CMDB 7.5, as noted below.
 Click here for reference information on impact and the data models.

Different versions of the CMDB have subtly different data models. Syncmappings can support multiple data models with datamodel declarations. CMDB data models are assigned simple integer values:

Data modelCMDB versionsEffect

6

7.6.03 and later

HasImpact and ImpactDirection attributes are set as appropriate

5

7.6.03 and later

Only to be used with legacy SIM version 7.4. BMC_Impact relationships with Name “ImpactOnly” are created

4

7.6.03 and later

No impact details are set by BMC Atrium Discovery. They may be set by Impact Normalization in the CMDB

3

7.6 before 7.6.03

BMC_Impact relationships with name “IMPACT” are created

2

7.5

BMC_Impact relationships with name “IMPACT” are created

BMC_ComputerSystem

The root Network Device node is mapped to a root BMC_ComputerSystem CI with the following attributes:

Relationships

Relationships are created to represent the connection between edge switches and hosts. Switch-to-switch connections are not mapped.

BMC_NetworkPort, BMC_LANEndpoint and BMC_IPEndpoint

Each Network Interface node connected to the root Network Device in the Discovery model is mapped to a BMC_NetworkPort, and its MAC address is mapped to a BMC_LANEndpoint.

Where Discovery has been able to connect a Network Device to a Host, a BMC_Dependency relationship is created between the two BMC_ComputerSystem CIs representing the host and the network device.

Differences from earlier BMC Atrium Discovery versions

BMC_NetworkPort was not created for Network Device nodes in versions prior to 9.0.

BMC_LANEndpoint

MAC addresses in the Discovery data model are stored in the conventional form with colons separating each pair of hexadecimal digits; in the CDM, MAC addresses are stored as just the hexadecimal digits, with no separating colons.
