MCTP Control Protocol Support
Computers & ServersMCTP Control Messages
What is MCTP Control?
MCTP Control Messages form the base management layer of the DMTF Management Component Transport Protocol. These messages handle endpoint discovery, endpoint ID (EID) assignment, routing table management, and message integrity verification across all MCTP transport bindings (SMBus, Ethernet, PCIe VDM). The MCTP control protocol is essential for establishing the management communication fabric in servers and data center platforms, enabling the BMC to discover and communicate with all managed components. Engineers debugging platform management issues need to decode MCTP control messages to verify that EID assignment, routing, and discovery are completing correctly.

How to Analyze MCTP Control with Acute Instruments
Connect your Acute logic analyzer to the MCTP transport interface (SMBus, Ethernet, or PCIe sideband signals).
Attach a ground lead to the target board's ground reference.
In the Acute software, select the MCTP Control protocol decoder and assign the transport signals to the correct input channels.
Configure the decoder for the specific transport binding being used.
Capture and view decoded MCTP control messages showing command codes, completion codes, EID assignments, and routing table entries.
