MCTP
MCTP (Management Component Transport Protocol), defined by the DMTF (Distributed Management Task Force), is a transport-independent protocol that can run over multiple physical layers such as PCIe, I²C, I3C, SMBus, UART, and Ethernet, enabling management and monitoring of servers and embedded systems.
When MCTP runs over I²C, I3C, or SMBus, management controllers (such as BMC, EC, NIC, GPU) can exchange standardized messages across the bus for applications like device monitoring, remote management, and power & thermal control. MCTP over I²C / SMBus has been widely adopted in servers and hardware monitoring, offering multi-device support and low power consumption; while MCTP over I3C provides higher speed, lower power, and more flexible device management, further enhancing system management efficiency.
Acute Technology provides logic analyzers with decoding support for MCTP over I3C / MCTP over I²C / MCTP over SMBus.

MCTP over I3C / I2C / SMBus Decoding Setup Steps
1. Click Quick Settings or Add Protocol Decode to select a protocol for logic analyzer capture.
2. Select MCTP over I3C / MCTP over I2C / MCTP over SMBus for decoding.
3. If you use Quick Settings, the system will recommend configurations for trigger type, sampling rate, voltage threshold, and channel settings.
4. Click the icon to access the Decode Settings screen.
Decode Settings
Channel: Specify the Logic Analyzer channel number connected to each signal end on the device under test.
Destination Address Configuration: Set the device address and its corresponding protocol.
Advanced Decode Setting: Display the detailed interpretation of the raw data.
