CHAPTER 3. IPMI INTERFACES
bits 0-6 - Channel medium type. Valid values are: 00h - reserved 01h - IPMB (I2C) 02h - ICMB version 1.0 03h - ICMB version 0.9 04h - 802.3 (Ethernet) 05h - Async serial/modem (RS-232) 06h - Other LAN 07h - PCI SMBus 08h - SMBus Versions 1.0/1.1 09h - SMBus Version 2.0 0Ah - reserved for USB 1.x 0Bh - reserved for USB 2.x 0Ch - System Interface 60h-7Fh - OEM All other values are reserved.
bit 7 - reserved bits 0-4 - Channel protocol type. Valid values are:
00h - reserved 01h - IPMB-1.0, used for acsIPMB, serial/modem basic mode, and LAN. 02h - ICMB-1.0, see section 3.6 03h - reserved 04h - IPMI over SMBus 05h - KCS, see section 3.2.2 06h - SMIC, see section 3.2.1 07h - BT from IPMI v1.0, see section 3.2.3 08h - BT from IPMI v1.5, see section 3.2.3 09h - Terminal mode, see section 3.10.3 1Ch-1Fh - OEM All other values are reserved.
bits 5-7 - reserved This field describes session information about the channel. See section 3.8 for details
on sessions. bits 0-5 - The number of sessions that have been activated on a given channel. This is only valid if the channel has session support. bits 6-7 - Session support, values are: 00b - channel does not support sessions. 01b - channel is single-session. 10b - channel is multi-session. 11b - channel is sessions based, but may switch between single and multiple
sessions. Vendor ID, used to specify the IANA number for the organization that defined the
protocol. This should always be the IPMI IANA, which is 7154 (decimal), or F2H, 1Bh, and 00H for these bytes.
