MCTP over SMBus/I2C (MCTP over SMBus/I2C)

MCTP over SMBus/I²C Protocol Analyzer settings. SMBus and I²C share the same bus and the same MCTP binding, so one Protocol Analyzer mode covers both. For Channel UI differences by product family, see Settings.

Settings

Settings:
- Decode Address: Configure which bus addresses are treated as MCTP endpoints. Open Address Configuration to add/remove rows. If the list is empty, the decoder uses MCTP specification defaults.
  - Address Configuration: + Add / Remove rows of Address and Type. Types include Static I2C (no MCTP decode), MCTP (I3C), MCTP (I2C). New-row Default Type: MCTP (I3C).
- SPDM Startup Setting: Fallback Signature / Hash / Ext counts used to parse SPDM bodies before algorithm negotiation latches sizes. Wrong values can mis-parse early SPDM messages.
  - Signature (S): Signature field length in bytes (0–512). Default: 256.
  - HashCnt (H): Hash count (1–15). Default: 2.
  - Ext-AsymCnt (A): Extended asymmetric count (0–15). Default: 1.
  - Ext-HashCnt (E): Extended hash count (0–15). Default: 1. Open Address Configuration under Decode Address to choose which bus addresses are decoded as MCTP endpoints:
+ Add / Remove: Add or remove address rows. If the list is empty, the decoder uses MCTP specification defaults.
Address: Bus address for that row.
Type: Static I2C (no MCTP decode), MCTP (I3C), MCTP (I2C). New-row Default Type: MCTP (I3C).
