| 2 | Describe an MCTP endpoint. It is an MCTP communication terminus. An MCTP |
| 3 | endpoint is a terminus or origin of MCTP packets or messages. The combined |
| 4 | functionality within a physical device that communicates using the MCTP |
| 5 | transport protocol and handles MCTP control commands. This includes |
| 6 | MCTP-capable management controllers and managed devices. |

| 12 | A locally defined identifier to distinguish each independent MCTP |
| 13 | network within a platform. The network IDs are used by the MCTP stack |
| 14 | to index separate MCTP Networks. This along with EID is used by upper |
| 15 | layer protocols to address the destination endpoint. |

| 20 | The logical address used to route MCTP messages to a specific MCTP |
| 21 | endpoint. A numeric handle (logical address) that uniquely identifies |
| 22 | a particular MCTP endpoint within a system for MCTP communication and |
| Patrick Williams | a134741 | 2022-12-06 10:56:22 -0600 | [diff] [blame^] | 23 | message routing purposes. Endpoint IDs are unique among MCTP endpoints |
| 24 | that comprise an MCTP communication network within a system. MCTP EIDs |
| 25 | are only unique within a particular MCTP network. That is, they can be |
| 26 | duplicated or overlap from one MCTP network to the next. This is also |
| 27 | referred to as "endpoint ID" and abbreviated as "EID". |

| 32 | List of MCTP message types supported by the MCTP endpoint. MCTP |
| 33 | message type is an enumeration that identifies the type of the |
| 34 | communication payload in an MCTP message. The well defined message |
| 35 | types are MCTP Control(0x00), PLDM(0x01), NC-SI over MCTP(0x02), |
| 36 | Ethernet over MCTP(0x03), NVM Express Management Messages over |
| 37 | MCTP(0x04) and SPDM over MCTP(0x05). There are ranges for vendor |
| 38 | defined message types. All the message types are specified in the |
| Patrick Williams | a134741 | 2022-12-06 10:56:22 -0600 | [diff] [blame^] | 39 | DSP0239 specification. A device that supports a given message type may |
| 40 | not support that message type equally across all buses that connect to |
| 41 | the device. |
