Hi there, I'm new to mrtg and SNMP also. I've been watching the list for about
a week and a half.

Here's what I've gotten on your first question. 
MIBs = Management Information Base and is a text file in hierarchical tree
format listing the Management Information fields that can be
monitored/set/reset, etc.

OID = Object Identifier which is the numeric sequence or path down the tree to
the value you want to monitor.

If you get ahold of the GETIF program (link below) and give it your Ascend's
address, then go to the MBrowser tab, Click the Walk button, you'll see the MIB
text description of the tree's leaf, and below that the OID. You'll also be
able to look at values and probably depending on your equipment, there is a
description about the value you're looking at. 

The SNMP FAQ in case you haven't found it:

http://www.snmp.com/FAQs/snmp-faq-part1.txt
http://www.snmp.com/FAQs/snmp-faq-part2.txt

As for the Ascend Max 6000, I can't help you specifically, but try this--
from your mrtg/run directory:

perl cfgmaker public@"your Ascend's IP address here" >>ascend.cfg

Don't include the quotes. I tried it, and after looking it over, I found the
port I wanted to monitor, then pasted that block into my mrtg.cfg file. (I also
ran GETIF to examine the MIB and OIDs, but I don't recall the link. Found it! 
GETIF 2.2 is at:  http://www.geocities.com/SiliconValley/Hills/8260/ )

I don't understand these things yet, but at least it's working!  <grin>
