Information Update 19
IP Address-Related Items
The following items are BMC updates concerning its IP address:
• The BMC IP address and the host port 1(the first one) IP address must be set to the same
value. This means that if the host is using DHCP, the BMC LAN channel must be turned off.
• Ensure that the gateway IP address is set to the correct subnet and the IP address is correct
when routing packets to the BMC. The BMC will properly respond to routed packets if only
the IP address is correct, but some packets may be lost if the gateway IP address is incorrect.
• Any host application that monitors ports 623 and 644 cannot be executed from port 1 (the
first one) of a server module. If you attempt this, the network packets will be sent to the BMC
instead of the host. Use port 2 instead.
Unsupported BMC Features and BMC Particulars
The following items describe BMC particulars and features that are not supported by the BMC on
this system.
• The IPMI Shell does not allow a user with administrator-level BMC user privileges to set and
change user privileges.
• The server module does not have an external serial connector; therefore, Terminal and Basic
mode are not supported through a serial port for out-of-band (IPMI) management.
NOTE:Console redirection can be set to the DRAC/MC module if use of its serial port is desired.
• Alerts (PET), Platform Event Filters (PEF), and DHCP are not supported as there are no alert
destination or IP Source options in the BMC setup.
• To prevent heavy ARP request traffic to the BMC, the BMC does not receive any ARP
requests as they are routed only to the host.
• The BMC sends gratuitous ARPs every 10 seconds to allow a remote host to discover the
BMC if the host’s operating system is not communicating.
• The server module’s front-panel power and KVM buttons are directly connected to the BMC.
If the BMC program becomes misconfigured or corrupt, the power button may not operate.
• Do not use the keyboard sequence to switch server modules or turn off the server module
when updating the BMC firmware. Otherwise, the update may fail. If this does occur, restart
the update.
