Flow
"Flow" is used to specify a particular part of the code. The way that flows are specified varies
depending on the module.
• 0x1 : This flow shows all the Subnet Management (SM) discovery, assignment routing and routing
processing.
• 0x2: This flow shows all the Subnet Management Agent (SA) related processing.
• 0x4 : This flow shows the trap related processing.
• 0x8: This flow shows the redundancy related processing.
• 0x10: This flow shows the Related Multipack Protocol (RMPP) related processing.
• 0x20: This flow shows the partition management related processing.
• 0x1000: This flow shows the internal state machine (may create more flow for more granularity for
path, mcast, …).
• 0x2000: This flow shows the user configuration management related processing.
• 0x4000: This flow triggers the Subnet Manager to take a snap shot of the current logging
information for the trace.
For example, use:
• 0x4001 to take a snapshot of the SM logging information.
• 0x4002 to take a snapshot of the SA information.
• 0x8000: This flow triggers the MAD packet to be displayed.
For example, use:
• 0x8001 to display SM MAD packets and SM related processing.
• 0x8002 to display MAD packets and SA related processing.
