CDM Mapping for SNMP Managed Device

This topic provides information about mapping for SNMP managed devices. The CIs created are described in this topic.

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.

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 model	CMDB versions	Effect
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.

BMC_ComputerSystem

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

Attribute	Details
Name	SNMPManagedDevice name attribute. The configured name of the SNMP managed device or SNMPManagedDevice name : computersystem name if the target is Remedyforce.

BMC_HostedSystemComponents	SYSTEMOS	BMC_ComputerSystem	BMC_OperatingSystem

BMC_NetworkPort, BMC_IPEndpoint and BMC_LANEndpoint

Each NetworkInterface node connected to the root SNMPManagedDevice in the BMC Helix Discovery model is mapped to a BMC_NetworkPort, and its MAC address is mapped to a BMC_LANEndpoint.

BMC_NetworkPort

Attribute	Details
Name	NetworkInterface interface_name
ShortDescription	NetworkInterface interface_name
Description	NetworkInterface name"
AutoSense	Yes (0) or No (1) or null if not known
FullDuplex	Yes (0) or No (1) or null if not known

Item	"Network interface card"

BMC_NetworkPort relationships

Relationship	Name	Source	Destination
BMC_HostedSystemComponents	SYSTEMHARDWARE	BMC_ComputerSystem	BMC_NetworkPort

BMC_LANEndpoint

MAC addresses in the BMC Helix 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.

Attribute	Details
Name	NetworkInterface mac_addr
NameFormat	"MAC"
ShortDescription	NetworkInterface mac_addr
Description	"MAC address on hostname"
Address	MAC address (no separating colons)
MACAddress	MAC address (no separating colons)

BMC_IPEndpoint

Each IPAddress node related to the root SNMP Managed Device node is mapped to a BMC_IPEndpoint CI:

Address	IP Address ip_addr
AddressType	IPv4 (1) or IPv6 (2)
DNSHostName	IP Address fqdns (first item in list)
ProtocolType	IPv4 (2) or IPv6 (3)
