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 vendors' responsibility to follow the standards. The standards are: • FibreAlliance (FA) MIB: Brocade supports version 3.0. • Fabric Element (FE) MIB: accepted by the Internet Engineering Task Force (IETF). Brocade supports FE_RCF2837.mib under the MIB-II branch in Fabric OS v4.x, 3.2.0, and v3.1.x and the experimental version, FE_EXP.mib, in Fabric OS v2.6.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 "Loading Brocade MIBs" on page 1-5 for more information. Once loaded, the MAX-ACCESS provides access levels between the agent and management station. The access levels are as follows: • not-accessible You cannot read or write to this variable. • read-create Specifies a tabular object that can be read, modified, or created as a new row in a table. • read-only - Public You can only monitor information. • read-write - Private You can read or modify this variable.
