2. • IPMI stands for intelligent platform management interface,
designed by the Intel, IPMI is now at revision 2.0.
• This standard accepted by DELL, IBM, INTEL and Others
• Through IPMI can monitor and control the BMC(Board
Management Controller) and Server
• In-Band Management
• - Communication over KCS
• -Out-of-Band Management
• IPMB, ICMB, PCI SMBus, LAN, Serial/Modem

11. SECURITY •
•
Define Users
Define privileges
(IPMI •
•
Encrypt communication with BMC
Version 2.0: RMCP/RMCP+: based on RAKP
messages (HMAC like protocol)
2.0) • Serial-Over-Lan is encrypted with RMCP+ only
13. IPV6 Support
• The current support for the IPMITool is
restricted to the IPV4 address
communication for the out-of-band. Our
plans are there to support he IPV6 protocol
as well. Development is in progress..
• This would be the major contribution to
the open source community as support for
the IPV6 Protocol.
