Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

The Open System Services (OSS) environment inherits these Guardian-environment defines and
also uses the RESCONF files.
For information about using the resolver in applications, see the TCP/IP Programming Manual or
the Open System Services Library Calls Reference Manual for OSS socket-library applications. For
information about the use of defines and name-resolution files in the OSS environment, see the
Open System Services Management and Operations Guide.
SNMP Support
SNMP support is provided on the NonStop system with CIP, similar to the SNMP support on
NonStop systems without CIP, with a few exceptions mentioned below. Using SNMP on the NonStop
host system, you can integrate your SNMP-based management application to manage and monitor
the NonStop system. In addition, SNMP support is provided on the CLIMs, but only within the
dedicated service LAN. This support is used by HP management applications, such as OSM, to
monitor the CLIMs.
SNMP on the NonStop Host System
The NonStop SNMP support in CIP is similar to SNMP support in the NonStop TCP/IP and TCP/IPv6
environments. For the CIP subsystem, the SNMP agent, EMS Trap Subagent, NonStop NET/MASTER
Trap subagent, Host Resources subagent and TRAP Multiplexer subagent and Manager are
supported. However, the TCP/IP subagent (TCPIPSA) and Ethernet subagent (ETHSA) are not
supported for CIP subsystem. For configuring the supported SNMP components on NonStop refer
to SNMP Configuration and Management Manual.
CLIM SNMP Support
SNMPv1 support is provided on the CLIM, but only on the dedicated service LAN. It provides an
extensible agent for responding to SNMP queries for management information. CIP supports
configuring the SNMP agent (snmpd) on the CLIM using the climconfig interface. The SNMP agent
supports many existing networking, storage, and server MIBs that are qualified for Debian TE.
These are used by the NonStop management applications, such as OSM, to monitor the CLIMs.
NOTE: SNMP trapdests must be configured on each CLIM for it to be able to send the SNMP
traps to the NonStop host.
When the eth0 is configured/modified by the user using config ip -add eth0 ip-address
or climconfig interface -modify eth0 ip-address, the climconfig tool updates the
/etc/defaults/snmpd configuration file with the new listening address as the dedicated service
LAN IP.
The SNMP agent on the CLIM has public as trap community string. Public is the default
community string to be used when sending traps. The SNMP agent on the CLIM has public for
read-only and read-write as community names. These are the read-only and read-write communities
that are used to access the agent.
CLIM SNMP Agents
CLIM SNMP agents monitor CLIM hardware presence and status and environmental status. CLIM
SNMP agents also monitor attached SAS enclosures hardware presence and status and
environmental status.
The OSM server issues SNMP calls to obtain the information and status. The OSM server also
creates an SNMPTMUX process to listen to traps generated by CLIM SNMP agents.
IP CLIM
The IP CLIM provides the physical interface to the network and performs the IP protocol processing.
It can be configured with either five copper or three copper and two fiber Ethernet interfaces for
