The two major components of HP SNMP/XL that you will use are:
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.
Access diagnostics information.
Obtain version reporting.
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 “Using SNMPUTIL” for more information on using SNMPUTIL.
