Network interface and address models
Network addresses are captured by BMC Discovery products as access points (inherited from BMC_AccessPoint ). Hence, they must always be associated with their parent instance of the computer through the BMC_HostedAccessPoint relationship. Also, a network address must have a relationship to the network interface for which it is configured. This relationship is modeled by using a BMC_Dependency relationship in which the network interface is the antecedent (source) and the network address is the dependent (destination).
For more information on modeling network addresses, including an illustration of the relationships used in the model, see Network-topology-models.
Logical identity of the BMC_NetworkPort class
Like any child instance of BMC_ComputerSystem, a network port is identified by the Name attribute in conjunction with the SystemName attribute that represents the name of the parent instance of the computer. Therefore, the Name attribute represents the local name of the CI in the context of the computer that is hosting it, as described in the following table:
Attribute | Usage |
|---|---|
Name | Identifies the network address that is suffixed by an index. The index uniquely identifies a MAC address for situations where multiple identical MAC addresses are configured within the same system. The index is generally the index of the MAC address entry in the SNMP MIB. |
NameFormat | Specifies the heuristic method used to generate the Name value. For instance, in many cases, network interfaces are best discovered and identified by using SNMP information. |
PhysicalIndex | Specifies the index, which must be a valid SNMP index related to the SNMP IF Table of the computer. |
SystemName | Identifies the name of the system, which must be the same as the parent instance of the BMC_ComputerSystem Name attribute. This attribute is automatically populated from the related CI when a weak relationship is created between the computer system and the operating system. |
Additional attributes of the BMC_NetworkPort class
The following table describes additional attributes of the BMC_NetworkPort class:
Attribute | Description |
|---|---|
AutoSense | The Boolean value that indicates whether the port can automatically determine the speed or other communications characteristics of the connected network media. |
Description | The description for the component. |
FullDuplex | The Boolean value that indicates whether the port is operating in full duplex mode (carrying signals in both directions). |
LinkTechnology | The enumeration of the types of link technologies, with values such as Unknown, Other, Ethernet, IB, FC, FDDI, ATM, Token ring, Frame relay, Infrared, Bluetooth, or Wireless LAN. |
ManufacturerName | The company that manufactured the component. |
MaxSpeed | The maximum bandwidth of the port in bits/second. |
NetworkAddresses | The list of strings specifying the network addresses for the port. |
PermanentAddress | The network address hard-coded into the port. This address can be changed by a firmware upgrade or software reconfiguration. If it is changed, update this field. If no hard-coded address exists for the network port, leave this attribute blank. |
PhysicalDescription | The physical description or location for the port, such as slot3/port4. |
PortType | The enumeration of the types of ports, with values such as Ethernet, FDDI, Token Ring, WAN, or Unknown. |
ShortDescription | A caption for the component. |
SerialNumber | The serial number of the component. |
SpeedConfigured | The maximum bandwidth of the port in bits/second. |
