Command Information
Request Information
| Byte | Data Field |
|---|---|
| NetFn | App 06h |
| CMD | 54h |
| 1 | Channel Number [7:4]-reserved [3:0]-channel number 0h-Bh, Fh=channel numbers Eh=retrieve information for channel this request was issued on |
| 2 | Payload Type [7:6]-reserved [5:0]-Payload Type number Typically 00h (IPMI) The Payload Type number is used to look up the Security Algorithm support when establishing a separate session for a given payload type |
| 3 | List Index [7]-1b=list algorithms by Cipher Suite 0b=list supported algorithms [6]-reserved [5:0]-List index (00h-3Fh), 0h selects the first set of 16, 1h selects the next set of 16, and so on 00h=Get first set of algorithm numbers. The BMC returns sixteen (16) bytes at a time per index, starting from index 00h, until the list data is exhausted, at which point it will 0 bytes or <16 bytes of list data Notes: When listing numbers for supported algorithms, the BMC returns a list of the algorithm numbers for each algorithm that the BMC supports on a given channel Each algorithm is listed consecutively and only listed once. There is no requirement that the BMC return the algorithm numbers in any specific order |
Response Information
| Byte | Data Field |
|---|---|
| 1 | Completion Code |
| 2 | Channel Number Channel number that the Authentication Algorithms are being returned for. If the channel number in the request was set to Eh, this will return the channel number for the channel that the request was received on |
| (3:18) | Cipher Suite Record data bytes, Cipher Suite Record Format. Record data is 'packed', there are no pad bytes between records. It is possible that record data will span across multiple List Index values The BMC returns sixteen (16) bytes at a time per index, starting from index 00h, until the list data is exhausted, at which point it will 0 bytes or <16 bytes of list data |
