OK, but if I have to write the script, why wouldn't I just write the 
script my way and automate it over ssh which already works instead of 
learning some new language and having to install some new agent 
everywhere to run it?

It's next to impossible to get or set a duplex setting via snmp. And 
non-trivial to figure out what switch port is connected to what device - 
OpenNMS does a reasonable job but if you activate all of its checks it 
can kill things that have full bgp routes.

It's messy any way you look at it.  We have a few different types of 
hardware and have to spend some time tuning the base install for new 
ones but that's something manageable.
