You will find the SNMP Object Navigator very helpful. It helps to determine which mibs is which and what it does.

Also, at some point you will have to look at the RFCs. Specifically RFC 3416 and RFC 1157.

To check the packets sent and received you can use Wireshark.

Lastly, Net::SNMP will block your application; if you need to do other tasks while Net::SNMP is waiting for a response, you can use POE::Component::Net::SNMP. This will especially help if your app has a UI.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
