Understanding SNMP basics 1 The agent can receive queries from one or more management stations and can send traps to up to six management stations. Understanding MIBs The management information base (MIB) is a database of monitored and managed information on a device, in this case a Brocade 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 Figure 4, the Brocade SW.MIB OID is: 1.3.6.1.4.1.1588.2.1.1.1 The corresponding name is: iso.org.dod.internet.private.enterprise.bcsi.commDev.fibreChannel.fcSwitch.sw The other branches are part of the standard MIBs, and the portions relevant to configuring SNMP on a Brocade switch are referenced in the remainder of this reference. iso (1) org (3) dod (6) internet (1) directory (1) mgmt (2) experimental (3) private (4) mib-2 (1) fcmgmt (94) enterprise (1) system (1) interface (2) connSet (1) bcsi (1588) sysDescr (1) sysObjectID (2) FIGURE 4 Brocade MIB tree location Brocade SW MIB 1.3.6.1.4.1.1588.2.1.1.1 Use a MIB browser to access the MIB variables: all MIB browsers perform queries and load MIBs.
