| 2 | LUN support [7:6] - LUN 3 (11b) support 00b = no commands supported on LUN 3 (11b) 01b = commands follow base IPMI specification. Commands exist on LUN, but no special restriction of command functions. Commands follow standard Optional/Mandatory specifications. 10b = commands exist on LUN, but some commands/operations may be restricted by firewall configuration. 11b = reserved [5:4] - LUN 2 (10b) support Note that a BMC uses LUN 10b for message bridging. The message bridging capability is enabled/disabled by enabling/disabling the Send Message command 00b = no commands supported on LUN 2 (10b) 01b = commands follow base IPMI specification. Commands exist on LUN, but no special restriction of command functions. Commands follow standard Optional/Mandatory specifications. 10b = commands exist on LUN, but some commands/operations may be restricted by firewall configuration. 11b = reserved [3:2] - LUN 1 (01b) support [1:0] - LUN 0 (00b) support |
| 3:18 | There are 32 possible Network Function (NetFn) pairs. The following bytes are treated as bitfields where each bit indicates the support for a given Network Function pair. Thus, it takes 4 bytes to fully list support for NetFn values under a given LUN. Since there are four possible LUNs for a management controller, a total of 16 bytes will return the settings for all four possible LUNs. 0b = NetFn pair is not used, 1b = NetFn pair is used byte 1, bit 0 corresponds to NetFn pair 0h,1h for LUN 00b byte 1, bit 7 corresponds to NetFn pair Eh,Fh for LUN 00b byte 2, bit 0 corresponds to NetFn pair 10h,11h for LUN 00b byte 2, bit 7 corresponds to NetFn pair 1Eh, 1Fh for LUN 00b … byte 16, bit 0 corresponds to NetFn pair 30h, 31h for LUN 11b byte 16, bit 7 corresponds to NetFn pair 3Eh, 3Fh for LUN 11b |
