1. Does the dude software come with a pack of MIB files?
Yes, there is a MIB library in The Dude, but it is not all-inclusive. You can manually add new MIB's to The Dude for your specific hardware. There is an MIB import function available. You can find this under Files in the menu.
2. Where can I get MIB files ?
Google is still your friend. There are several repositories for MIB files, as well as many manufacturers making the MIB files available. Try
http://www.mibsearch.com for a searchable database of MIBs.
3. How do I use the MIB file to extract the information ?
MIB files are commented (most of the time) to detail what functions are available. If you are not that familiar with the structure of MIBs, try
http://en.wikipedia.org/wiki/Management ... ation_Base for an overview. Unfortunately, this is not an instant gratification topic. Look at us talking when there's science to be done.
