SNMP
SNMP is widely used and supported on a variety of servers,
workstations, bridges, routers, and hubs. SNMP support also
includes other computer system resources, such as Fibre Channel
and RAID controllers.
SNMP implementations vary from simple device information
display and collection of statistics, to complex configuration
management systems. SNMP is implemented by creating an MIB
that describes the objects to be managed. SNMP establishes
standards to access and manage various types of data regarding
attached resources within a computer network.
Management Information Base
As with any network management system, the core component of
SNMP is the database containing the information about the objects
to be managed. For SNMP this is referred to as the Management
Information Base (MIB). A MIB is written using the ASN.1
(Abstract Syntax Notation One) format as described in ISO 8825-2.
This format allows the exchange of structured data, especially
between application programs over networks, by describing data
structures in a form that is independent of machine architecture
and application software.
Every system resource to be managed is represented as an object
and the MIB is a collection of these objects. In a network
environment each system (workstation or server) maintains a copy
of the MIB containing the current status of the objects which it
defines. The MIB information is maintained by a software agent. At
the operating system level, a master agent controls the system MIB.
Adaptec supplies a subagent that contributes its own MIB to the
system MIB. This subagent also responds to requests from the
master agent for information as needed.
Note: For additional security, all of the Adaptec MIB data is
read-only. The Adaptec SNMP feature is intended only for
gathering inventory information and for processing status
and alert information.
