Product Structure
The two major components of HP SNMP/XL that you will use are:
* The SNMP stack.
* SNMPUTIL.
The SNMP Stack
The SNMP stack runs as a system process and is the backbone of HP
SNMP/XL. Its main functions are:
* To provide the interface to the network via the UDP (User Datagram
Protocol) interface.
* To perform the ASN.1 encoding/decoding for both incoming and
outgoing PDUs (Protocol Data Units).
* To provide event message services.
* To access MIB data for the agent.
The SNMP stack interfaces to the connectionless mode transport service
(UDP subsystem) via NetIPC. Other subsystems that are used include the
MPE/XL ports subsystem and the MPE/XL process management subsystem.
SNMPUTIL
The SNMPUTIL is a program file that provides the following functions:
* Manually startup and shutdown the SNMP stack.
* Generate SNMP requests and format responses back to the user.
* Generate SNMP traps.
* Access diagnostics information.
* Enable tracing.
* Enable logging.
* Obtain version reporting.
* Obtain subsystem status.
You may use SNMPUTIL to manually startup or shutdown SNMP. (Normally,
SNMP is started and stopped automatically when the transport is started
or stopped.) SNMPUTIL is then responsible for creating the SNMP process
on startup and sending a shutdown message to the stack process for
shutdown, in order to start and stop the SNMP stack. See chapter 3 for
more information on using SNMPUTIL.
