ib-agent switch
Synopsis:
The ib-agent switch command and its arguments are used to configure the Subnet-Management Agent (SMA)
node strings for internal switches. A node string is a descriptive string used to identify an object.
Syntax:
ib-agent switch guid
The syntax is described in the following table:
Command Modes:
Global-configuration mode.
Privilege Level:
Unrestricted and HP Fabric 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 fabric 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 HP Fabric Clustering
System subnet.
Internally, the fabric 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.
