This appendix describes the Simple Network Management Protocol (SNMP)
capabilities that MSA2000 Family storage systems support. This includes standard
MIB-II, the Fibre Alliance SNMP Management Information Base (MIB) version 2.2
objects, and enterprise traps.
Topics covered in this appendix are:
"Introduction" on page 227
"Standard MIB-II Behavior" on page 228
"Enterprise Traps" on page 228
"FA MIB 2.2 SNMP Behavior" on page 229
"External Details for Certain FA MIB 2.2 Objects" on page 238
"Configuring SNMP Event Notification in SMU" on page 241
"SNMP Management" on page 241
"Enterprise Trap MIB" on page 242
"FA MIB 2.2 and 4.0 Differences" on page 245
MSA2000 Family storage systems can report their status through SNMP. SNMP
provides basic discovery using MIB-II, more detailed status with the FA MIB 2.2,
and asynchronous notification using enterprise traps.
SNMP is a widely used network monitoring and control protocol. It is an
application layer protocol that facilitates the exchange of management information
between network devices. It is part of the Transmission Control Protocol/Internet
Protocol (TCP/IP) protocol suite.
SNMP enables network administrators to manage network performance, find and
solve network problems, and plan for network growth. Data is passed from SNMP
agents reporting activity on each network device to the workstation console used to
oversee the network. The agents return information contained in a Management
Information Base (MIB), which is a data structure that defines what is obtainable
from the device and what can be controlled (turned on and off, etc.).
