the port. If there is no traffic going across what should otherwise be a busy port, refer to status LEDs next to the port or check the physical connections.

Traffic can be analyzed across individual ports or aggregated total across interface cards.

About Logging and Tracing

In general, two types of messages are generated: Events and Traces.

About HP Fabric Events

Event messages are generated whenever a significant event occurs in the system, and cannot be turned-off or configured by the user.

The following types of scenarios fall into the Events category:

•A Subnet Manager has been started (created)

•A new HP Fabric node is in-service

•An existing HP Fabric node is out-of-service

•A new HP Fabric multicast group is created

•A new multicast member is added to an existing multicast group

•An existing multicast group is deleted

About Tracing

Trace messages are only generated when the user has explicitly enabling tracing for debugging/trouble-shooting purposes. By default, tracing is disabled.

The trace feature has different levels of control to allow the user to dynamically select the amount and/or type of tracing information to be generated.

•Application

•Module

•Trace-Level

•Flow

Application

The number of applications may change between releases. The numbers assigned to applications may also change. Check application and module number assignments using CLI help (i.e.,?) before setting a trace level.

Module

"Module" is used to specify what module of code (library), in the selected application tracing should be configured for.

The number of modules may change between releases. The numbers assigned to modules may also change. Check module number assignments using CLI help before setting trace levels.

Trace-Level

"Trace-Level" is used to specify the verbosity of the output. You can specify different levels of verbosity to control the amount of the tracing information that is generated.

Trace levels are described in the following table:

Table 7-7 Trace Level Descriptions

Trace Level	Description
NO_DISPLAY	No tracing information will be generated. This is the default setting to ensure the best SM
	performance.
VERY_TERSE	Not currently used.
