Understanding Mibs; Hp Mib Tree Location - HP StorageWorks 2/64 - Core Switch Reference Manual

Understanding MIBs

The MIB is a database of information monitored and managed on a device, in this case an HP
StorageWorks switch. The MIB structure can be represented by a tree hierarchy. The root splits into three
main branches: International Organization for Standardization (ISO), Consultative Committee for
International Telegraph and Telephone (CCITT), and joint ISO/CCITT. These branches have short text
strings and integers (OIDs) to identify them. Text strings describe object names, while integers allow
software to create compact, encoded representations of the names.
Each MIB variable is assigned an object identifier (OID). The OID is the sequence of numeric labels on the
nodes along a path from the root to the object. For example, as shown in
1.3.6.1.4.1.1588
The corresponding name is:
iso.org.dod.internet.private.enterprise.bsci
The other branches are part of the standard MIBs. The portions relevant to configuring SNMP on an HP
StorageWorks switch are referenced in the remainder of this manual.

Use a MIB browser to access the MIB variables; all MIB browsers perform queries and load MIBs.
Since different vendors vary the information in their private enterprise MIBs, it is necessary to verify their
information. The Fibre Channel MIB standards dictate that certain information be included in all MIBs; it is
the vendor's responsibility to follow the standards. The standards are:
• FibreAlliance (FA) MIB: HP supports version 3.0.
• Fabric Element (FE) MIB: accepted by the Internet Engineering Task Force (IETF).
HP supports FE_RCF2837.mib under the MIB-II branch in Fabric OS 4.x, 3.2.0, and 3.1.x and the
experimental version, FE_EXP.mib, in Fabric OS 2.6.x and 3.0.x. This latest version of the FE MIB
references the FRAMEWORK.MIB and, based on the MIB browser, it is necessary to load this MIB before
the FE.MIB. See
