HP UX 11i v2 Networking Software manual Interface ib, Link-trap, Config-if-ib submode

Command Modes: Global-configuration mode.

Privilege Level: Unrestricted and InfiniBand read-write users.

Usage Guidelines: A subnet-management agent (SMA) is the intermediary between a network manager and the network entities it manages, such as the internal InfiniBand switches and host channel adapters. The subnet management agent maps the operations between managed conceptual objects and the physical resources inside the system chassis, and routes event notifications from locally managed objects to remote entities.

Each node in the fabric has a subnet management agent (SMA) to shuttle communication requests between the node and the subnet manager. Communication between the subnet manager and the subnet management agent is done using the common management datagram (MAD) message structure. This structure entails the passing of subnet management packets (SMP).

The subnet management agent receives and transmits subnet management packets to and from the subnet manager. The subnet management packets never extend beyond their respective local InfiniBand subnet.

Internally, the InfiniBand switch is comprised of 36 switch chips. Each switch chip runs its own subnet management agent and can be viewed by the subnet manager as a unique entity. Change the node-string for a channel-adapter or switch to make it easier to identify.

Examples: The following example changes the node string of a switch.

HP-IB(config)# ib-agent switch 00:05:ad:00:00:00:13:da node-string "Switch 0, LID 2" HP-IB(config)# exit

Defaults: This command has no defaults.
