10.7.6.1 MCTP Commands Support
Table 10-81 lists the MCTP commands supported by I211.
10.7.6.1.1 Error Conditions
In some cases , the I210 may not be ready to react to a received MCTP command. In these cases, a
response with ERROR_NOT_READY (0x04) completion code. is returned. In this case, it is
recommended to wait 300 ms before retrying the command.

0x01 Set Endpoint ID
Assigns an EID to the endpoint at the given physical
address.
N/A Yes
0x02 Get Endpoint ID
Returns the EID presently assigned to an endpoint. Also
returns information about what type the endpoint is and
its level of use of static EIDs. See Section 10.7.6.1.2 for
details.
