CHAPTER 3. IPMI INTERFACES

Request 0 1 2-n Response

Bits 0-3 - Channel Number

Bits 4-7 - reserved Parameter Selector. This selects the entry in the table that you want to set.

The data for the parameter. You must look up the entry in table 3.16 for the exact contents, it depends on which entry you are setting.

Completion code. Standard completion codes, plus: 80h - Parameter not supported

  • 0

    81h - Attempt to set the “set in progress’ value (parm 0) when the parameter is not in

the free (set complete) state. 82h - Attempt to write a read-only parameter.

Table 3.15 shows the command used to get LAN parameters.

Bits 0-3 - Channel Number Bits 4-6 - reserved Bit 7 - If 1, only get parameter revision Parameter Selector. This selects the entry in the table that you want to get. Set Selector. Some parameters are in an array, this tells which array element to set. Set to zero if the parameter does not have a set selector. Block Selector. Some parameters have two levels of arrays (an array inside of the array). The Set Selector is the first level array specifier, this is the second level. No standard LAN parameters use this, although OEM ones might. Set to zero if the parameter does not have a block selector.

Completion code. Standard codes, plus: 80h - parameter not supported Parameter revision. Format is: Bits 0-3 - Oldest revision parameter is backward compatible with Bits 4-7 - Current parameter revision Parameter data. This will not be present if bit 7 of byte 0 of the response is set to 1. The contents of this depends on the particular parameter being fetched, see table 3.16 for the parameters.

The LAN Configuration Table

The LAN Configuration table has an unusual locking mechanism (although it is usual for IPMI). Parameter zero is a lock. If you set the value to one, it will only succeed if the value is zero. Thus, to lock the table, you
