cfgmaker doesn't know about a specific piece of network gear, and Cisco
routers are fairly problematic, as there are a number of variations.
There are at least three different OID's that may be used, and the
instance is variable per platform (and some platforms have more than one

I have a template that grabs that information, but it has a lot of
