SNMP Configuration
and Management
Manual
Abstract
This manual describes how to install, start, configure, and stop the HP Simple Network
Management Protocol (SNMP) Agent and subagents. The SCF commands used by
SNMP are described. This manual also discusses the objects in the Management
Information Bases (MIBs) used by the agent and subagents. The SNMP Agent and its
subagents comply with SNMP Requests for Comment (RFCs) so that SNMP-compliant
management applications, known as SNMP managers, can manage various resources
on an HP NonStop™ host.
Product Version
SNMP Agent (T9576G06), T9576H01)
Supported Release Version Updates (RVUs)
This manual supports the G06.24 RVU and all subsequent G-series RVUs and the
H06.03 RVU and all subsequent H-series RVUs until otherwise indicated by its
replacement publication.
