CDM Mapping for SNMPManagedDevice

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

The CIs created are described below.

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.

BMC_ComputerSystem

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

Attribute	Details
Name	SNMPManagedDevice `name` attribute. The configured name of the SNMP managed device
ShortDescription	SNMPManagedDevice `name`
Description	SNMPManagedDevice `name`
CapabilityList	List of device capabilities
HostName	SNMPManagedDevice `name`
LastScanDate	SNMPManagedDevice `last_update_success` – the date and time the device was last scanned
ManufacturerName	SNMPManagedDevice `vendor`
Model	SNMPManagedDevice `model`
PrimaryCapability	`Switch`, `Router`, or other network device enumeration value
SerialNumber	SNMPManagedDevice `serial`
SystemOID	SNMPManagedDevice `sysobjectid`
Category	"`Network`"
Type	"`Switch`" or "`Router`"
Item	"`Data switch`" or "`Access router`"

BMC_OperatingSystem

The root SNMPManagedDevice node is also mapped to a BMC_OperatingSystem CI:

Attribute	Details
Name	"`os_vendor os_type os_version`"
ShortDescription	"`os_type os_version`"
Description	"`os_vendor os_type os_version`"
ManufacturerName	SNMPManagedDevice `os_vendor`
MarketVersion	SNMPManagedDevice `os_version`
Model	SNMPManagedDevice `os_type`
OSType	`Other` (0)
VersionNumber	SNMPManagedDevice `os_version`
Category	"`Software`"
Type	"`Operating System Software`"
Item	"`Network Operating System`"

BMC_OperatingSystem relationships

Relationship	Name	Source	Destination
`BMC_HostedSystemComponents`	`SYSTEMOS`	`BMC_ComputerSystem`	`BMC_OperatingSystem`
`BMC_Impact`	`IMPACT`	`BMC_OperatingSystem`	`BMC_ComputerSystem`

BMC_NetworkPort, BMC_IPEndpoint and BMC_LANEndpoint

Each NetworkInterface node connected to the root SNMPManagedDevice in the 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
LinkTechnology	Ethernet (2)
ManufacturerName	NetworkInterface `manufacturer`
PermanentAddress	NetworkInterface `mac_addr`
PortType	Ethernet (2)
Speed	NetworkInterface `raw_speed`
Category	"`Hardware`"
Type	"`Card`"
Item	"`Network interface card`"

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.

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)
ProtocolType	Ethernet (14)
Category	"`Network`"
Type	"`Address`"
Item	"`MAC Address`"

BMC_IPEndpoint

Each IPAddress related to the root SNMPManagedDevice is mapped to a BMC_IPEndpoint CI:

Attribute	Details
Name	IPAddress `ip_addr`
NameFormat	"`IP`"
ShortDescription	IPAddress `ip_addr`
Description	IPAddress `name`
Address	IPAddress `ip_addr`
AddressType	IPv4 (1) or IPv6 (2)
DNSHostName	IPAddress `fqdns` (first item in list)
ProtocolType	IPv4 (2) or IPv6 (3)
SubnetMask	IPAddress `netmask`
ManagementAddress	Yes (1) if the IP address was used to scan the host; No (0) if not. (Not in CMDB 7.5.)
Category	"`Network`"
Type	"`Address`"
Item	"`IP Address`"

NetworkPort and Endpoint relationships

Relationship	Name	Source	Destination
`BMC_HostedSystemComponents`	`SYSTEMHARDWARE`	`BMC_ComputerSystem`	`BMC_NetworkPort`
`BMC_HostedAccessPoint`	`HOSTEDACCESSPOINT`	`BMC_ComputerSystem`	`BMC_IPEndpoint`
`BMC_HostedAccessPoint`	`HOSTEDACCESSPOINT`	`BMC_ComputerSystem`	`BMC_LANEndpoint`
`BMC_Dependency`	`ENDPOINTPORT`	`BMC_NetworkPort`	`BMC_LANEndpoint`
`BMC_Impact`	`IMPACT`	`BMC_ComputerSystem` (network device)	`BMC_ComputerSystem` (host)

BMC_IPConnectivitySubnet

Discovery Subnet is mapped to BMC_IPConnectivitySubnet:

Attribute	Details
Name	Subnet `ip_address_range`
ShortDescription	Subnet `ip_address_range`
Description	Subnet `ip_address_range`
AddressType	IPv4 (1) or IPv6 (2)
PrefixLength	IPAddress `prefix_length`
SubnetMask	IPAddress `netmask`
SubnetNumber	Subnet `ip_address_range`
Category	"`Network`"
Type	"`Subnet`"
Item	"`TCP/IP`"
