Alex, I change all the RRAs.

My switch is a FastEthernet switch, this invalid data
originated from manual reload or clear Counters.

Where is "modify its upper limits"? In the rrdcreate
graph?

I create my rrd file with this options:
DS:ds0:COUNTER:500:0:100000000 \
DS:ds1:COUNTER:500:0:100000000 \

To limit the maximum rate to 100mb. This is correct??

Thank's 
Diego.
