SNMP is a protocol used to communicate management information between network management applications and HP BladeSystem Onboard Administrator. The Onboard Administrator supports SNMP Version 1 and several groups from the standard MIB-II MIB. Additional information about the enclosure infrastructure is available in the HP Rack Information MIB. The Rack Information MIB (CPQRACK-MIB) is part of the Insight Management MIBs and is found on the Management CD in the ProLiant Essentials Foundation Pack.
The SNMP Settings screen enables you to enter system information and community strings and designate the management stations that can receive SNMP traps from the Onboard Administrator. If you select Enable SNMP, then the Onboard Administrator responds to SNMP requests over UDP port 162. Port 162 is the standard UDP port used to send and retrieve SNMP messages.
In the System Information subcategory, information about the Onboard Administrator SNMP system can be enabled and configured.
The Enable SNMP checkbox is not selected by default. When enabled, the Onboard Administrator can be polled for status and basic information. Only when you enable the Write Community string can a SNMP client clear SNMP alerts and status. Clear the Enable SNMP checkbox to disable SNMP access to the Onboard Administrator.
|System Location||0 to 20 characters including all printable characters and the space||The SNMP location of the enclosure, typically used to identify the physical or topographical location of the Onboard Administrator.|
|System Contact||0 to 20 characters including all printable characters and the space||The name of the system contact, used to identify an individual or group of individuals who are to be contacted in the event of any status change in the HP BladeSystem Onboard Administrator.|
|Read Community||0 to 20 characters including all printable characters and the space||The Read Community string allows the client to read information but not to manipulate the alerts or status of the HP BladeSystem Onboard Administrator through SNMP. The default community name is “public” and will allow a user to receive notification traps and alerts, but not to change or manipulate the status.|
|Write Community||0 to 20 characters including all printable characters and the space||The Write Community string allows the client to manipulate alerts of HP BladeSystem Onboard Administrator status through SNMP. You can remotely clear alerts and mark them as “viewed” or otherwise through their SNMP management client through the SNMP agents. The default value for the Write Community string is public.|
After editing any field in this subcategory, click Apply to save the changes.
In the SNMP Alert Destinations subcategory, the IP addresses and community strings for the SNMP management clients are configured so that any alert or trap from the Onboard Administrator is sent to the appropriate system with the appropriate community string.
|IP Address||###.###.###.### where ### ranges from 0 to 255||The management station IP address|
|Community String||0 to 20 characters including all printable characters and the space||A text string that acts as a password. It is used to authenticate messages that are sent between HP SIM and Onboard Administrator.|
Adding SNMP alert destinations
Use the IP Address field to enter the IP address for management clients to which the traps are to be sent. Directly below the IP Address field, in the Community String field, enter the appropriate community string. After you enter the IP address and community string, click Add. You can add a maximum of eight SNMP alert destinations.
Removing SNMP alert destinations
Select the IP address from the list containing the trap destinations and click Remove.
Click Send Test Alert to send a test SNMP trap to all of the configured trap destinations. You must enable SNMP to use this function.
