L3 topology and IP connectivity models
A subnet divides large networks into smaller, more efficient sub networks in a logical partition. A BMC_IPConnectivitySubnet instance represents a group of related BMC_IPEndpoint instances that can communicate with each other as members of a subnet. The BMC_IPConnectivitySubnet class describes the characteristics of the subnet.
Example of modeling servers and routers on a subnet
The following figure illustrates a server and a router that belong to the same subnet:
Key attributes of BMC_IPConnectivitySubnet
The following table describes key attributes of BMC_IPConnectivitySubnet class:
Attribute | Usage |
|---|---|
Name | Identifies the IP address of the entire subnet, which is formatted according to the appropriate convention as defined in the AddressType attribute. When AddressType is 1 (IPV4), the Name is built by concatenating the SubnetNumber and SubnetMask separated by a forward slash. |
NameFormat | Specify the heuristic method used to generate the Name value, which must be set to IP. |
Additional attributes for BMC_IPConnectivitySubnet
The following table describes attributes that provide additional information about BMC_IPConnectivitySubnet:
Attribute | Description |
|---|---|
AddressType | An enumeration that describes the format of the Name and SubnetNumber properties in BMC_IPConnectivitySubnet:
|
PrefixLength | A prefix length for IPv6 addresses in the IP subnet (AddressType property is 2). |
SubnetMask | The mask for the starting address of the IPv6 IP subnet (AddressType is 1). |
SubnetNumber | The IP address of the entire subnet. This value must be equal to the Name attribute. |
Relationships for components on a subnet
The BMC_InIPSubnet relationship is used to relate the BMC_IPEndpoint instances and the respective BMC_IPConnectivitySubnet instances.
