We have discovered only 21 devices and have 3266 ports. We will have over 2,000 devices.

I want to ignore ports where ifDescr is null or whitespace. Currently, I have:

$config['bad_if_regexp'][] = array("/^$/","","/\A\s*+\z/");

This is _not_ working, or at least it is not working for EXISTING, DISCOVERED ports.

Please show me the way!

I want to be able to remove the ifDescr from the network gear and have it stop being monitored and vice-versa (add an ifDescr and have it start being monitored).

Thanks! I'm sure I just have something messed up in the regex.
