Incorrect interface bandwidth measurement

Hi,

I am reading SNMP  Objects ifHCOutOctets(Counter64) and ifHCInOctets ( Counter64 ) from switch interfaces every 60 secs and then Transformation Average Delta Per Second along with script $1*8 to get interface bandwidth in bits/sec. The problem is that this is giving me exaggerated values in full load condition - consider 11 or 12 Mbps on a 10 Mbps channel. Please help in sorting this issue.

Regards,
Deep

You can check raw values in history of a DCI and do the calculation manually, but I am afraid that's just the data that this switch provides.
