Clicking on the BMC Setting tab of session in the Viewing Window (as shown in Figure 7-1) gives you detailed information on the BMC LAN Configuration, SNMP trap configuration and serial communication port of the BMC.

In order to support the power-down state management capability under the IPMI specification, the manager has to configure the proper MAC address for each IP address.  To deliver an IP packet to a receiver, the sender needs to know the receiverˇ¦s MAC address or the gatewayˇ¦s MAC address.  ARP (Address Resolution Protocol) is used to get the MAC address from the IP address.  While the managed systemˇ¦s OS is running, the network protocol stack will take care of this function.  However, when the managed system is in a power down state, this function cannot be accomplished.  Therefore, each MAC address has to be configured manually.

The BMC and the OS running on a managed system may use different IP addresses for security reasons.  For example, the OS may use 66.201.4.73 (which can be reached by public access) while the address for BMC may be set to 192.168.1.55, which can only be reached in a private LAN.  But, LAN MAC addresses must be the exact same.  If the BMC uses a private IP address, you have to make sure that the managerˇ¦s system can communicate with the private IP address for the BMC on a managed system.

BMC LAN Configuration

This shows the IP address, LAN MAC, Gateway IP, Gateway MAC and Subnet Mask of the BMC and allows you to modify them. NOTE: please make sure that the MAC address of the LAN and the gateway for the BMC are correct before updating it by clicking the Update button.  Be careful to enter the correct values, especially for the LAN MAC.  If you enter the wrong LAN MAC, it will not be able to connect to that system any more. 

If you accidentally enter a wrong LAN MAC value, you may use the IPnMAC.exe command in the IPMI Solution/Utility subfolder on this CD to update it.  To activate IPnMAC.exe,,which is a DOS command, you must first boot your managed system to DOS, and then execute IPnMAC.exe on the managed system.

 

SNMP

This shows the SNMP trap configuration of the system needing to receive the SNMP traps generated by the BMC and allows you to modify them. To change the configuration on the BMC, type in the SNMP community name in the Community text field and the IP address and MAC address in the SNMP Trap Receivers table in the SNMP group, and then click the Update button.

The SNMP Trap may have multiple destinations. When any critical error occurs, an SNMP trap packet will be sent to all receivers in the list.  To remove an SNMP receiver, you may change both IP and MAC addresses to 0.0.0.0 and 00:00:00:00:00:00 respectively, and then click Update.

On the system receiving the SNMP traps, an SNMP trap receiver software needs to be installed and run. The managed system will send out an SNMP trap packet to receivers at the moment the event occurs.  If an SNMP trap receiver is not running, the trap packet is discarded and wonˇ¦t be queued anywhere.

RS232 / MODEM (Only available for IPMI 1.5)

This shows the configuration of the RS232 interface on the BMC.  It is used to initialize the RS232 port and the installed modem, if any.  The RS232 port is the box-header (Figure 7-2) on the BMC and is a dedicated serial port.

Baud Rate: the baud rate for serial connections (does not affect paging settings).

Modem Init String: the modem initialization string for serial connections (does not affect paging settings).
