I'm fond of one-to-one relationships between physical entities and
configuration files.

I don't like this because you end up serializing all your requests.
Especially when you've got the possibility of SNMP timeouts, you could
easily take much, much longer than you'd like to do your polling.  With
multiple independent config files, I've found that decently-sized servers
can simply run all of them in parallel and finish sooner.

How many devices for these ports? What operating system?
