[mrtg] OID that MRTG is actually using when gathering bandwidth data - Cisco4506

[Thomas Olsen]

Hi Alex
 
This makes perfectly sense. Thanks a lot for the information. I am using OIDView, so I found the OIDs you refer to right away.
 
BTW: These values are Octets. Can I use that value directly for graphing; meaning is 1 octet the same as 1 bit/s?
 
Thanks again.
 
/Thomas
