Introduction to SNMP 1 called Management Information Bases (MIBs). When an agent supports a standard MIB, it agrees to provide and make available the variables listed in the MIB. A MIB is a hierarchical tree of groups and variables. Operators at a network management station enter a command with supported groups and variables from the MIB. NMS Read status information with GetRequest command or Set a variable to a value with SetRequest command Agent (Use MIB to identify variable) Managed Device MIB Variable a Variable b Variable c Variable d Variable e Variable f Variable g - Actual Variable (object) (x)y (x)y (x)y (x)y (x)y Figure 1-2 Retrieving or Setting Values Using MIBs Standard MIBs Standard MIBs are those created and approved by IETF and other Internet standards bodies and are readily available for use with SNMP network management stations. The standard MIBs provide a baseline of common operations across a wide variety of managed devices. Chapter 2 describes the standard MIBs used by the various McDATA products. Standard MIBs supported by McDATA products are: • MIB-II (Internet MIB) as described in RFC 1213: supported by all switches and directors. • Fibre Alliance (FCMGMT) MIB, version 3.1: supported by EFC Server, Sphereon 4500 Fabric Switch, Sphereon™ 3216 Fabric Switch, Sphereon 3232 Fabric Switch, Intrepid™ 6064 Director, Intrepid 6140 Director, ES-3016, ES-3032, and ED-6064. 1-4 E/OS SNMP Support Manual
