Simple Network Management (SNMP) Support

Simple Network Management Support provides a mechanism for a centrally located management workstation to monitor the activity of remote computers and network services. An SNMP management framework includes the following:

SNMP management workstation that requests information
Master agent that handles and responds to the requests
Application-specific subagent that translates the SNMP requests for and responses from the application
The application that is managed, in this case it is the HP-UX AAA Server

The HP-UX AAA server includes an SNMP application subagent. At startup, the server automatically activates its SNMP subagent and the subagent registers the application with the master agent. The HP-UX AAA server can exchange information with any SNMP master agent software that supports the AgentX protocol.




	NOTE: See RFC 2741 for more information about the AgentX protocol.

Information exchanged through SNMP is represented by objects in the Managed Information Base (MIB). The MIB is defined by the IETF for use with network protocols in the Internet community. The MIB includes extensions for RADIUS authentication and accounting servers which are supported by the HP-UX AAA Server. See Chapter 21 “MIB Objects” for more information.

Setting Up SNMP to Monitor the HP-UX AAA Server

Use the following steps to set-up an SNMP workstation to monitor the HP-UX AAA Server:

Install and start up an SNMP manager and master agent on the SNMP workstation. You will need to copy the SNMP configuration file, iaaaAgent.conf, to the /usr/local/share directory on the SNMP workstation. The SNMP master agent that you use must support and be configured for the agent X protocol.
After you have installed the AAA server, load the RADIUS MIB files (included with the server) into the SNMP manager according to your SNMP managers instructions.
Enter http://IP-Address:Port/aaa as the URL (or https://IP-Address:Port/aaa for HTTPS) in an Internet browser to access the Server Manager graphic interface. IP-Address is the machine that hosts the managers program. Port is the port used by the Server Manager program for communication. By default the value is 8081 (8443 for HTTPS). If you are prompted for a username and password, you should enter the values specified during installation.
Select the Server Properties link from the Navigation Tree located in the left frame of the browser and then select the Enable SNMP property.
On the Server Properties screen that appears, select Enable SNMP.
Select the Yes radio button for the property and then select the Modify button.
Select the Administration link from the Navigation Tree.
Select the Start button. If the server successfully starts, a green GO icon should appear next to the name of the server in the Status Frame (in the lower left corner of the programs interface). The AAA subagent will check the appropriate sockets and TCP ports for an active master agent. When the subagent detects the running master agent, it will register with the master agent, and you can begin to send SNMP requests from the workstation to the server.
You should follow the instructions for your SNMP manager to configure it to monitor the RADIUS information that you are interested in.
