# Class CIM_IBSubnetManager
extends CIM_Service

An Infiniband Subnet Manager (SM) is an entity responsible for configuring and managing an IB subnet. It uses Subnet Management Agents (SMA) to access and manage individual nodes. The SM is hosted in the context of a specific computer system (i.e., hosted by an instance of UnitaryComputerSystem), as described by the HostedService association. Note that there may be multiple SMs operating in a subnet, but only the elected master is allowed to perform configuration functions.

Name | Data Type | Default Value | Qualifiers
--- | --- | --- | ---
Name | Data Type | Value
Priority | uint8 |
Description | string | Administratively assigned priority for this SM, used to establish the master. A higher number indicates a higher priority and likelihood of becoming the master. The property value can be reset by the master SM.
MappingStrings | string | MAD.IBTA | SMInfo | Priority
Write | boolean | true
State | uint16 |
Description | string | Enumerated value that indicates the Subnet Manager's State. The values are fairly self-explanatory except for "Not Active". This value indicates that the SM is available to participate in the subnet, but has not been given permission. A value "Unknown" (0) is also defined.
