Much thanks to Jay and Anson. I have it working and polling the ports. I
just have a problem with the descriptions.

snmpwalk shows the data lined up like this:
IF-MIB::ifAlias.1 = STRING: 3640 Router

So I tried alias for ifdesc it blanks out the area in which it should be
placing the alias name.

So SNMP sees the names for the Alias OID, but they are blank when
cfgmaker runs. I see the snpo lines for eth/type/name/descry but no
alias which sounds like that's where my problem is.

I don't know about Dell for sure.  One of --ifref=nr or --ifref=name 
should work out of the box.

Scroll down in the referenced link to the Configuration section.  The 
choices for ifref and the advantages of each are given.  Note that this 
controls how MRTG communicates with the monitored device and not how the

results will be displayed.  --ifdesc controls how it is displayed.  They

can be different.

The goal of --ifref is to identify a descriptor that:

1.  Uniquely defines each interface
2.  Is not likely to change
