HPI MIB for SAF-HPI B-01-01. When using this MIB it is strongly recommended to use the SNMPv3 protocol due to security concerns. Additionally if fine grain access configuration is desired, for example to manage access to individual columnar objects, the SNMP configuration should use VACM (View Based Access Control Model - RFC 2275). This MIB defines the HPI instrumentation based on 'Service Availability Forum Hardware Platform Interface' (SAI-HPI-B.01.01). This MIB module defines a set of objects that allow the management of entities on a variety of hardware platforms. The abstractions presented in this MIB are derived from the Service Availability Forum Hardware Platform Interface specification version SAI-HPI-B.01.01. The MIB views a hardware platform as a collections of physical entities that can be managed individually. A logical collection of entities comprises a management domain. Each entity has a common set of attributes reflected in the entity table. Entities may have additional categorical attributes that may exist in one or more of the hotswap table, control table, sensor table, watchdog table, inventory control table and config table. The hotswap table defines management attributes for an entity that supports hotswap, generally referred to as a FRU. The controls table defines variables for reading and setting controls associated with an entity. The sensors table defines variables for reading sensors associated with an entity as well as controlling event generation for that sensor. The watchdog table defines variables for reading watchdog associated with an entitry. The inventory control defines variables for reading inventory resources and changing the settings.
