Table 34 Get AuthCode command request and response data
Data fieldIPMI request
data byte
number
[7:6] - Authentication type / Integrity algorithm number1
00b = IPMI v1.5 AuthCode algorithms
01b = IPMI v2.0/RMCP+ algorithm number
For [7:6] = 00b, IPMI v1.5 AuthCode number:
[5:4] - Reserved
[3:0] - Hash type
0h = Reserved
1h = MD2
2h = MD5
3h = Reserved
4h = Reserved (change from IPMI v1.5). This results in an error completion code.
5h = OEM proprietary
All other = Reserved
For [7:6] = 01b, IPMI v2.0/RMCP+ Integrity algorithm number
5:0] - Integrity algorithm number. The user password is used as the starting key for the Integrity
algorithm, instead of session-dependent keys such as the session integrity key. The “none” Integrity
number (0) is illegal and results in an error completion code.
Channel number2
[7:4] - Reserved
[3:0] - Channel number
User ID. (Software will typically have to use the get user name command to look up the user ID
from a user name).

For IPMI v1.5 AuthCode number:
AuthCode =2:17
For IPMI v2.0 Integrity algorithm number
Resultant hash, per selected Integrity algorithm. Up to 20 bytes. An implementation can elect to return
a variable length field based on the size of the hash for the given integrity algorithm, or can return a
fixed field where the hash data is followed by 00h bytes as needed to pad the data to 20 bytes.

Set channel access command
This command is available to the MC.
This command is used to configure whether channels are enabled or disabled, whether alerting is
enabled or disabled for a channel, and to set which system modes channels are available under.
This configuration is saved in non-volatile storage associated with the MC. The choice of factory
default setting for the non-volatile parameters is left to the implementer or system integrator.
