BMC IP Address and external connection
The BMC IP address for a particular embedded NIC is always different from the IP address of the Server’s
operating system.
The BMC supports static and DHCP sourced IP address assignment on all of its management NICs. The IP
address source parameter must be set to “static” before the IP address, subnet mask, or gateway address can
be manually set.
If the BMC’s IP address on a LAN channel changes while a LAN session is in progress over that channel, the
BMC does not take action to close the session except through a normal session timeout. The remote client must
re-sync with the new IP address.
Secure Shell (SSH)
Secure Shell (SSH) connections, when RMM3 is present, are supported for SMASH-CLP sessions to the BMC.
BMC Users
The BMC supports the IPMI 2.0 user model including support for User ID 1. 15 user IDs are supported. These 15
users can be assigned to any channel. The following restrictions are placed on user-related operations:
 User names for User IDs 1 and 2 cannot be changed. These will always be “” (Null) and “root” respectively.
 User 2 (“root”) will always have the administrator privilege level.
 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 as “” (Null), “root,” or any other existing user name.
Table 19. Feature Comparison
Users User Name Password Status Characteristics
User 1 Null Null Disabled Only Password can be changed.
User 2 root superuser Disabled Only Password can be changed.
User 3 test1 superuser Disabled Both user name and password can be changed.
User 4 test2 superuser Disabled Both user name and password can be changed.
User 5 test3 superuser Disabled Both user name and password can be changed.
User 6-15 undefined undefined Disabled Both user name and password can be changed.
Changing the password is recommended if using user 1 or 2, and changing both user name and password if
using user 3-5.
Session Support
Maximum/Minimum session support varies by interface type:
 IPMI Over LAN – Minimum of four sessions
 Embedded WebServer (when advanced features are enabled) – Minimum of four sessions
 Media Redirection – Minimum of two sessions
 KVM – Minimum of two sessions
 Serial Channel – One session only
Remote Management Module 3 (RMM3)
The RMM3 provides the integrated BMC with an additional dedicated network interface. The dedicated interface
consumes its own LAN channel. The RMM3 supports advanced features such as KVM redirection and Media
redirection.
The web server is available on all enabled LAN channels. If a LAN channel is enabled, properly configured, and
accessible, the web server is available.
For security reasons, the null user (user 1) may not be used to access the web server. The session inactivity
timeout for the embedded web server is 30 minutes. This is not user-configurable.
