Programming Examples
This section describes the sample managers that are provided with Manager Services.
Table 2-1
provides a summary of sample manager functions; some of the managers use
the UDP application program interface (API) to communicate over TCP/IP, while others
support both UDP and IPC.
Example Files
The sample managers are provided as a collection of source code and header files that
can be converted into executable managers by using the build script included with the
files.
Manager Logic
The source code files for the sample managers are summarized in Table 2-2. When first
installed, these files are located in the following locations:
•
In the Guardian environment: $<dsv>.ZSNMPMEX
•
In the OSS environment: /usr/tandem/snmpapps

MIB object tree specified at invocation. Uses MIB
compiler output to convert OIDs to MIB object names.
SNMPTRAP UDP Sends a Trap packet containing one or more variable
bindings specified at invocation.
SNMPMON UDP Prints the contents of Response and Trap packets
