L2 topology and physical connectivity model
A BMC_ConnectivitySegment instance represents a group of related instances of BMC_LANEndpoint of a particular type (such as Ethernet, token ring, or fiber channel) that can intercommunicate without the assistance of bridging or routing services. The BMC_ConnectivitySegment instances are sometimes referred to as members of the same collision domain. The BMC_ConnectivitySegment class describes the characteristics of the group or segment.
Example of modeling a server and a switch
The following figure illustrates a server and a switch, with the server having one NIC directly connected to a network interface of the switch:
Key attributes of BMC_ConnectivitySegment
The following table describes key attributes of BMC_ConnectivitySegment:
Attribute | Usage |
|---|---|
Name | Identifies the connectivity segment, which uses the following information and generates a hash code as resulting value:
|
NameFormat | Specifies the heuristic method that is used to generate the Name value, which must be set to OID (object identifier). |
Additional attributes for BMC_ConnectivitySegment
The following table describes attributes that provide additional information about BMC_ConnectivitySegment:
Attribute | Description |
|---|---|
ConnectivityType | An enumeration that describes the type of technology used:
|
Count | The current number of endpoints connected to this segment. When this value equals 2, it indicates a direct connection between the two network ports interconnected by means of the segment. |
Relationships for network interfaces
The BMC_InSegment relationship is used to relate the BMC_LANEndpoint instances and the respective BMC_ConnectivitySegment instances.
