Supports Sessions No Yes Yes Yes Yes No No No - - No 6.10.1 User Model The BMC supports the IPMI 2.0 user model. 15 user IDs are supported. These 15 users can be assigned to any channel. The following restrictions are placed on user-related operations: 1. User names for User IDs 1 and 2 cannot be changed. These are always "" (Null/blank) and "root" respectively. 2. User 2 ("root") always has the administrator privilege level. 3. All user passwords (including passwords for 1 and 2) may be modified. User IDs 3-15 may be used freely, with the condition that user names are unique. Therefore, no other users can be named "" (Null), "root," or any other existing user name. 6.10.2 IPMB Communication Interface The IPMB communication interface uses the 100 KB/s version of an I2C bus as its physical medium. For more information on I2C specifications, see The I2C Bus and How to Use It. The IPMB implementation in the BMC is compliant with the IPMB v1.0, revision 1.0. The BMC IPMB slave address is 20h. The BMC both sends and receives IPMB messages over the IPMB interface. Non-IPMB messages received by means of the IPMB interface are discarded. Messages sent by the BMC can either be originated by the BMC, such as initialization agent operation, or by another source. One example is KCS-IPMB bridging. 6.10.3 LAN Interface The BMC implements both the IPMI 1.5 and IPMI 2.0 messaging models. These provide out-ofband local area network (LAN) communication between the BMC and the network. See the Intelligent Platform Management Interface Specification Second Generation v2.0 for details about the IPMI-over-LAN protocol. Revision 1.1 61 Intel order number G24881-004

6.10.1
User Model
The BMC supports the IPMI 2.0 user model. 15 user IDs are supported. These 15 users can be
assigned to any channel. The following restrictions are placed on user-related operations:
1.
User names for User IDs 1 and 2 cannot be changed. These are always “” (Null/blank)
and “root” respectively.
2.
User 2 (“root”) always has the administrator privilege
level.
3.
All user passwords (including passwords for 1 and 2) may be modified.
User IDs 3-15 may be used freely, with the condition that user names are unique. Therefore, no
other users can be named “” (Null), “root,” or any other existing user name.
6.10.2
IPMB Communication
Interface
The IPMB communication interface uses the 100 KB/s version of an I
2
C bus as its physical
medium. For more information on I
2
C specifications, see
The I
2
C Bus and How to Use It.
The
IPMB implementation in the BMC is compliant with the
IPMB v1.0, revision 1.0.
The BMC IPMB slave address is 20h.
The BMC both sends and receives IPMB messages over the IPMB interface. Non-IPMB
messages received by means of the IPMB interface are discarded.
Messages sent by the BMC can either be originated by the BMC, such as initialization agent
operation, or by another source. One example is KCS-IPMB bridging.
6.10.3
LAN Interface
The BMC implements both the IPMI 1.5 and IPMI 2.0 messaging models. These provide out-of-
band local area network (LAN) communication between the BMC and the network.
See the
Intelligent Platform Management Interface Specification Second Generation v2.0
for
details about the IPMI-over-LAN protocol.
