CDM Mapping for Network Device

This topic provides information on mapping for network devices. 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

Note

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.


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 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.

The BMC_UPS class exists as a hosted system component, though given the nature of UPS devices and their usual standalone nature, BMC_ComputerSystem is a more appropriate mapping. Particularly as they are IP connected and the BMC_ComputerSystem class provides additional flexibility that the BMC_UPS class does not. 

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 BMC Discovery model is mapped to a BMC_NetworkPort, and its MAC address is mapped to a BMC_LANEndpoint.

Where BMC Discovery connects 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.
