Simple Network Management Protocol-SNMP

THE SMI \nThe SMI specifies the allowable data types in the MIB, and it spells out the ways data can be represented. Also, it defines a hierarchical naming structure that ensures unique, unambiguous \nnames for managed objects, which are the components of a MIB. Compared with the objects \nthat general purpose programmers use to build applications, SNMP-managed objects are very \nsimple and stripped down. MIB objects typically have six or so attributes. For instance, an \nobject usually has a name, such as iflnErrorsortcpAttemptFails; an object identifier in dotted \ndecimal form, such as 1.3.6.1.2.1.2.2.1.14; a syntax field, which selects one of several possible \ndata types such as Integer, IPAddress, or Counter; an access field, which selects among "notaccessible;&s; "read-only;&s; "read-write;&s; and "write-only"; a status field consisting of either \n"mandatory;&s;"optional;&s;"deprecated;&s; or "obsolete"; and a text description of the object.
