1.6The MIB Compiler

Method routine function prototypes

The subtree_TBL.C file is an object file that contains the following:

An array of integers representing the OIDs for each MIB variable

An array of OBJECT structures

An initialized SUBTREE structure

1.7SNMP Versions

The extensible SNMP software supports SNMP Version 2, based on RFCs 1901 through 1908, including:

The SNMP Version 2 structure of management information for SNMP Version 2 (SMI Version 2) and textual conventions.

The eSNMP library API (SNMP Version 2), variable binding exceptions, and error codes.

SNMP Version 1 and SNMP Version 2 requests. Both versions are handled by the master agent. SNMP Version 2 specific information from the subagent is mapped, when necessary, to SNMP Version 1 adherent data (according

to RFC 2089). For example, if a management application makes a request using SNMP Version 1 PDUs, the master agent replies using SNMP Version 1 PDUs, mapping any SNMP Version 2 SMI items received from subagents. In most cases, subagents created with a previous version of the eSNMP API do not require any code changes and do not have to be recompiled. The circumstances under which recoding or recompiling are required are described in Section 1.7.1.

1.7.1Using Existing (SNMP Version 1) MIB Modules

Existing SNMP Version 1 MIB subagent executable files should be compatible with the current SNMP Version 2 master agent without the need to recompile and relink, with the following exceptions:

Any program that relies on TCP/IP Services Version 4.1 or 4.2 kernel data structures or access functions may run but may not return valid data. Such programs should be rewritten.

Programs linked against UCX$ACCESS_SHR.EXE, UCX$IPC_SHR.EXE, or other older shareable images (except for UCX$ESNMP_SHR.EXE, which is described in the next list item) may not run even when relinked. You may need to either rewrite or both rewrite and recompile such programs. Note that the Chess example image (UCX$CHESS_SUBAGENT.EXE) has been updated and renamed TCPIP$CHESS_SUBAGENT.EXE.

For programs linked against certain versions of UCX$ESNMP_SHR.EXE:

Images associated with the following versions of TCP/IP Services will run correctly without the need to relink them:

Version 4.1 ECO 9 and later

Version 4.2 ECO 1 and later

The installation of TCP/IP Services provides a backward-compatible version of UCX$ESNMP_SHR.EXE in the SYS$SHARE directory. Do not delete this image.
