A-2SNMPManagement Information BaseAs with any network management system, the core component ofSNMP is the database containing the information about the objectsto be managed. For SNMP this is referred to as the ManagementInformation Base (MIB). A MIB is written using the ASN.1 (AbstractSyntax Notation One) format as described in ISO 8825-2. This formatallows the exchange of structured data, especially betweenapplication programs over networks, by describing data structuresin a form that is independent of machine architecture andapplication software.Every system resource to be managed is represented as an object andthe MIB is a collection of these objects. In a network environmenteach system (workstation or server) maintains a copy of the MIBcontaining the current status of the objects which it defines. The MIBinformation is maintained by a software agent. At the operatingsystem level, a master agent controls the system MIB. Adaptecsupplies a subagent that contributes its own MIB to the system MIB.This subagent also responds to requests from the master agent forinformation as needed.Note: For additional security, all of the Adaptec MIB data isread-only. The Adaptec SNMP feature is intended only forgathering inventory information and for processing statusand alert information.Management ConsoleThe SNMP management console is usually a client workstationrunning SNMP-based management software. The console softwarecan be from any vendor who provides SNMP management consolesoftware.
