HP-UX AAA Server A.08.00.01 Administrator's Guide

23 Simple Network Management Protocol (SNMP) Support
Simple Network Management Protocol (SNMP) 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 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. 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 35:
“MIB Objects” (page 557) for more information.
IMPORTANT: The SNMP application sub-agent supports only IPv4 clients. In a mixed
environment (comprising of IPv4 and IPv6 clients), the sub-agent can return information
on the IPv4 clients only. Information on the IPv6 clients will not be returned.
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:
1. 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 AgentX protocol.
2. 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.
3. 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
