RMCP+
Besides RMCP defined by DMTF, BMC also supports RMCP+
protocol defined in IPMI 2.0.


Integrity Algorithm types supported: none, HMAC-SHA1-
96, HMAC-MD5-128, MD5-128.


CBC-128.
Serial Over LAN
BMC supports 1 IPMI (Spec v2.0) specific SOL session. BMC
supports redirect data from UART interface.
Time Sync
In S400-X44E BMC design, BMC does not have a local RTC to
know what time it is. Each time the server powers on, BIOS will
use Set SEL Time command to initialize BMC time. The remote
console program interpret this time as pre-initial.
SEL
BMC supports IPMI 1.5/2.0 standard SEL operation. It can keep
to maximum 909 entries SEL log. Event happened in BIOS side
will be logged by using Add SEL Entry command. BMC will
store them in FLASH, the time stamp field will be filled by BMC.
When SEL is full, the new SEL won’t be logged but will go
through PEF as usual. If AC powers off, all SELs will remain in
NV.
