IB Subnet Manager MIB Cheng Yang Carl Yang Edwin Tsang August, 2004

MIB Overview Enables out-of-band management of IB Subnet Manager configuration Enables out-of-band configuring and monitoring of IB fabrics. Modeled as close as IB management model specified in the IB spec. This is an update of a previous submitted draft, dated Nov

MIB Overview Complements SMA MIB to provide management functions in the following area: –SM Management –More powerful Node and Port Management –Switch Management –Partition Management –Multicast Management –Path/MultiPath/Trace Management –Physical Topology –Service/Service Association Management –GUID Management –Notification and Traps

Major Updates from Last Version Notifications/Traps group added. Compliance statements added. GUID Information table added. SL and VL mapping table removed for lack of interest.

Subnet Manager Configuration Subnet Manager Configuration Table. –List of all the SMs on the device. Indexed by Subnet Prefix. Creating/deleting a row has the effect of adding/removing a SM. –Configuring SMs’ running parameters: Admin and Running Status Sweep Interval Response Timeout LID range Default LMC Master-Standby Polling configuration. etc..

Node and Port Management Node Information Table –List of all the nodes and their NodeInfo per subnet. Read-only table Indexed by Subnet Prefix and NodeGUID Port Information Table –List of all the ports and their PortInfo per subnet. Indexed by Subnet Prefix, NodeGUID and PortNumber –Configuring of PortInfo attributes: LinkWidth/Speed, PortState, LinkDownDefState, MKeyProtBits, etc.

Switch Management Switch Information Table. –List of all the SwitchInfo per subnet. Indexed by Subnet Prefix and NodeGUID. –Configuring of SwitchInfo paramenters: DefaultPort, DefaultPrimaryMulticastPort, DefaultNonePrimaryMulticastPort, Packet LifeTime, etc.

Partition Management Partition Table –List of Partitions, and Partition Membership per subnet. Indexed by Subnet Prefix, Partition Key and membership vector index. Partition Configuration Group –Create or delete partitions. –Add or remove partition memberships per port.

Multicast Management Multicast Group Table –List of MC Group Information per subnet Indexed by Subnet Prefix and MGID Multicast Member Table –List of MC Memberships for each MC Group. Issues with Multicast operations. –Who creates multicast groups? Implicit/explicit join?

Discovery of other SMs Subnet Manager Information Table –Discovers a list of all the SMs per subnet. Indexed by Subnet Prefix and PortGUID. –List the status of each SM.

Physical Topology/Link Link Table –List of all the Link Records per subnet, allows application to have physical topology information.

Path/MultiPath Information Path Information Request Table –Allows query of PathInfo. Path Information Result Table –Retrieve the PathInfo query result. MultiPath Information Request Table –Allows query of MultiPath Info. MultiPath Information Result Table –Retrieve the MultiPath query result.

Trace Record Trace Information Request Table –Query for the TraceInfo Trace Information Result Table –Retrieve result of TraceInfo query.

Serivce Management Service Table –List of Service Records Service Association Table –List of Service Associations –Add or delete Service Name-Service Key mapping.

Notifications/Traps 14 Generic notifications –InService/OutOfService –MCGroupCreated/Deleted –LinkStateChanged –IntegrityThreshold/BufferOverrunThreshold –FlowControlWatchdogTimerExpire –CapabilityMaskChange –SystemImageGuidChange –BadMKey/BadPKey/BadQKey/BadSwitchPKey Vendor specific notifications

Work to be done. Security Considerations. Collect more feedbacks from reviewers. Pass MIB Doctor’s examination.
