> I have a 200+ port switch with the interfaces almost constantly going up/down due to additions/removals of host.  Do I need to recreate the config file every time a change is made, or can I just uncomment every port in the config?  My thought was that if I uncomment everything, mrtg will puke (it commented it out for some reason).

If you use Cisco CATALYST 2900XL or 3500XL switches, there are bug in older
IOSes. After unplugging interface he goes "administratively down".
Only "operational down" is correct. It's repaired in IOS before about 6 months.
You must upgrade IOS.
