Hi, being new to this switch monitoring thing please bear with me. I have a
Cisco 2908XL switch (8 port 10/100) and have configured mrtg to run on an nt
box....
my graphs end up being flat or with minimal traffic.... :(
with 0 - 30 bytes being the average..... now i know it's bigger than that
here is my default cfgmaker file(i went back to it after my fooling around
didn't produce any results):

i have been reading up on SNMP and was wondering which OID MRTG looks at and
does it figure it out just by subtracting the old form the new???
any help would be appreciated
thanks in advance,
